Frequently Asked Questions - Weldforce 141GL Weldclass

What type of welding wire should I use with the Weldforce 141GL?

For standard MIG welding, use 0.6–0.8 mm solid steel wire with shielding gas. For gasless (flux-cored) welding, use 0.8–1.0 mm flux-cored wire.

What gas is recommended for MIG welding?

A mix of 75% Argon / 25% CO₂ (C25) is ideal for mild steel. Pure CO₂ can be used but may produce more spatter.

How do I set the correct wire feed speed and voltage?

Refer to the chart inside the wire feed compartment. A good starting point: for 0.8 mm steel wire at 0.8 mm thickness, set voltage to 4 and wire speed to 6 (mid-range). Adjust based on weld appearance.

What is the duty cycle of this machine?

The duty cycle is 15% at 140 A (meaning weld for 1.5 minutes, then rest 8.5 minutes). At lower currents, duty cycle increases (e.g., 60% at 90 A, 100% at 70 A).

Can I weld aluminum with the Weldforce 141GL?

It is not recommended for aluminum. This machine is designed for steel and stainless steel. For aluminum, you need a spool gun (not included) and pure argon gas, but performance is limited.

How do I change the contact tip or liner?

To change the contact tip, unscrew the old tip from the torch neck. To change the liner, loosen the set screw at the torch end, pull out the old liner, and insert a new one cut to length. Refer to the manual for exact steps.

Why is the wire feeding erratically or not feeding?

Check that the drive rollers are matched to wire size (0.6, 0.8, 1.0 mm). Adjust the tension knob so the wire drives smoothly without slipping. Ensure the liner is clean and not kinked.

What does the thermal overload light mean?

The yellow Thermal Overload LED lights up when the machine has overheated. Let it cool for 15–20 minutes with the fan running before resuming work.

How do I clean and maintain the welding machine?

Regularly blow out dust from the ventilation slots with compressed air. Check and clean the wire feed rollers and liner. Inspect the torch and cable for damage. Store in a dry, clean place.

What is the power requirement for this welder?

It requires a 230 V (single phase) 15 A power supply. Ensure the outlet is properly grounded and fused. Do not use an extension cord if possible; if necessary, use a heavy-duty one (< 2.5 mm² cross-section).

Controls Explained

LCD Current & Voltage Display Meters

The voltage (V) meter will display voltage output, based on setting/position of fine/top adjustment knob. The current (A) meter will display amperage output, based on setting/position of main/bottom adjustment knob. The digital meters are very sensitive and accurate, so it is not abnormal to observe some fluctuations them.

Controls

The MIG voltage control is essentially the power in the welding arc that sets the heat. The wire speed feed simply controls the rate at which the welding wire is fed into the weld pool.

For any voltage position setting, there will be a specific corresponding 'sweet spot' in the wire feeding speed that will give the smoothest and most stable welding arc. The correct wire feeding speed for a given voltage setting is affected by welding wire type and size, shielding gas, welding material and joint type.

It is recommended to set the welding voltage as desired and then slowly adjust the wire speed until the arc is smooth and stable. When reaching this point, if the penetration/ heat input is too much/not enough, adjust the voltage setting and repeat the process.

Overload Indicator Lamp

Lights when duty cycle is exceeded and thermal protection is activated. When thermal protection is activated, welding output will be disabled until machines cools sufficiently and overload indicator lamp goes out. Also may activate with inverter circuit failure issues.

Power Supply

Electrical Connection

The Weldforce 141GL is designed to operate on a 10A 240V AC power supply.

Extension Leads

If an extension cord must be used, it should be minimum cable core size 2.0mm^2 for length of up to 10m, or minimum 2.5mm^2 for length up to 20m. Using extension leads of over 20m is not recommended.

Generator Use

This machine has a wide input power variation tolerance (\~170-265V), allowing it to operate off generator power. However, this machine is NOT designed for frequent generator use and is NOT protected against poor quality power or voltage spikes. Any damage caused by generator power supply is not covered under warranty.

If generator power must be used, generator size should be not less than 7kva. Avoid using poor, low quality generators as these have the greatest risk of power spikes etc. A suitable quality generator should have a THD (total harmonic distortion) rating of not more than 6%. Most reputable generator supplier will be able to specify the THD ratings on their product.

Operating Environment

Adequate ventilation is required to provide proper cooling for the Weldforce 141GL. Ensure that the machine is placed on a stable level surface where clean cool air can easily flow through the unit. The Weldforce 141GL has electrical components and control circuit boards which may be damaged by excessive dust and dirt, so a clean operating environment is essential.

Tips & Tricks

Duty Cycle Rating

Welding duty cycle is the percentage of actual welding time that can occur in a ten minute cycle. E.g. 15% at 140 amps - this means the welder can weld at 140 amps for 1.5 minutes and then the unit will need to be rested for 8.5 minutes. All duty cycle ratings are based on an ambient air temperature of 40°C with 50% humidity, which is the international standard for such a rating. In an environment with temperature s exceeding 40°C, the duty cycle will be less than stated. In ambient temperature less than 40°C, duty cycle performance will be higher.

Wire Jam Troubleshooting

• If wire jam occurs when the torch becomes hot, this is often because the heat causes the wire and the tip to expand (which shrinks the hole in the tip). Using a slightly oversize tip can prevent this – eg: for 0.9mm wire, use a 1.0mm tip.
• Do NOT over-tighten the drive roll tension – this will accelerate wear of the drive system, may distort the wire & will cause further wire feed problems.
  • Refer to page 13-14 for more troubleshooting tips.

Gasless MIG Welding Guide

MIG Basic Welding Techniques

Two different welding processes are covered in this section (GMAW and FCAW), with the intention of providing the very basic concepts in MIG welding, where a welding gun is hand held, and the electrode (welding wire) is fed into a weld puddle, and the arc is shielded by a gas (GMAW) or flux cored wire (FCAW).

Gasless Flux Cored Arc Welding (FCAW)

This is an electric arc welding process which fuses together the parts to be welded by heating them with an arc between a continuous flux filled electrode wire and the work. Shielding is obtained through decomposition of the flux within the tubular wire.

In the case of gasless wire, you should always 'drag' the torch (don't push).

Position of MIG Torch
(Fig 1-3)

Drag Pull

The angle of MIG torch to the weld has an effect on the width of the weld.

The welding gun should be held at an angle to the weld joint. (See Secondary Adjustment Variables below).

Hold the gun so that the welding seam is viewed at all times. Always wear the welding helmet with proper filter lenses and use the proper safety equipment.

CAUTION!!

Do not pull the welding gun back when the arc is established. This will create excessive wire extension (stick-out) and make a very poor weld.

The electrode wire is not energized until the gun trigger switch is depressed. The wire may therefore be placed on the seam or joint prior to lowering the helmet.

(Fig 1-4)

(Fig 1-5)

Vertical Fillet Welds (Fig 1-6)
10^ to 20^
Longitudinal Angle

(Fig 1-7)

Distance from the MIG Torch Nozzle to the Work Piece

The electrode wire stick out from the MIG Torch nozzle should be between 10mm to 20mm. This distance may vary depending on the type of joint that is being welded.

Travel Speed

The speed at which the molten pool travels influences the width of the weld and penetration of the welding run.

Preselected Variables

Preselected variables depend upon the type of material being welded, the thickness of the material, the welding position, the deposition rate and the mechanical properties.

These variables are:

• Type wire
• Size wire

Primary Adjustable Variables

These control the process after preselected variables have been found. They control the penetration, bead width, bead height, arc stability, deposition rate and weld soundness.

These variables are:

• Arc Voltage
  • Welding current (wire feed speed)
• Travel speed

Secondary Adjustable Variables

These variables cause changes in primary adjustable variables which in turn cause the desired change in the bead formation. They are:

1. Stick-Out (distance between the end of the contact tube (tip) and the end of the electrode wire). Maintain at about 10mm stick-out
2. Wire Feed Speed. Increase in wire feed speed increases weld current. Decrease in wire feed speed decreases weld current.

1. Nozzle Angle. This refers to the position of the welding gun in relation to the joint. The transverse angle is usually one half the included angle between plates forming the joint. The longitudinal angle is the angle between the centre line of the welding gun and a line perpendicular to the axis of the weld. The longitudinal angle is generally called the Nozzle Angle and can be either trailing (pulling) or leading (pushing).

Establishing the Arc and Making Weld Beads

Before attempting to weld on a finished piece of work, it is recommended that practice welds be made on a sample metal of the same material as that of the finished piece.

The easiest welding procedure for the beginner to experiment with MIG welding is the flat position. The equipment is capable of flat, vertical and overhead positions.

For practicing MIG welding, secure some pieces of 16 or 18 gauge (1.5mm or 2.0mm) mild steel plate (150 x 150mm). Use (0.8mm) flux cored gasless wire.

Setting of the Power Source

Power source and Current (Wire Speed) setting requires some practice by the operator, as the welding plant has two control settings that have to balance. These are the Current (Wire Speed) control and the welding Voltage Control.

The welding current is determined by the Current (Wire Speed) control, the current will increase with increased Current (Wire Speed), resulting in a shorter arc. Less Current (Wire Speed) will reduce the current and lengthen the arc. Increasing the welding voltage hardly alters the current level, but lengthens the arc. By decreasing the voltage, a shorter arc is obtained with a little change in current level.

When changing to a different electrode wire diameter, different control settings are required. A thinner electrode wire needs more Current (Wire Speed) to achieve the same current level. A satisfactory weld cannot be obtained if the Current (Wire Speed) and Voltage settings are not adjusted to suit the electrode wire diameter and the dimensions of the work piece.

If the Current (Wire Speed) is too high for the welding voltage, “stubbing” will occur as the wire dips into the molten pool and does not melt. Welding in these conditions normally produces a poor weld due to lack of fusion. If, however, the welding voltage is too high, large drops will form on the end of the wire, causing spatter. The correct setting of voltage and Current (Wire Speed) can be seen in the shape of the weld deposit and heard by a smooth regular arc sound.

Troubleshooting

The general approach to fix MIG problems is to start at the wire spool then work through to the MIG torch. There are two main areas where problems occur with MIG, Porosity and Inconsistent wire feed.

Wire feeding problems can be reduced by checking the following points.

Troubleshooting - Wire Feed
Fault	Cause
Feed roller driven by motor in the cabinet slipping.	Wire spool brake is too tight.
Wire spool unwound and tangled.	Wire spool brake is too loose.
Worn or incorrect feed roller size	Use a feed roller matched to the size you are welding.
	Replace feed roller if worn.
Wire rubbed against the misaligned guides affecting the wire feed.	Misalignment of inlet/outlet guides.
Liner blocked with swarf.	Increased amounts of swarf are produced by the wire passing through the feed roller when excessive pressure is applied to the pressure roller adjuster.
	Swarf can also be produced by the wire passing through an incorrect feed roller groove shape or size.
	Swarf is fed into the conduit liner where it accumulates thus reducing wire feed.
Incorrect or worn contact tip.	The contact tip transfers the weld current to the electrode wire. If the hole in the contact tip is too large then arcing may occur inside the contact tip resulting in the wire jamming in the contact tip.
	When using soft wire such as aluminium it may become jammed in the contact tip due to expansion of the wire when heated. A contact tip designed for soft wires should be used.
Poor work lead contact to work piece.	If the work lead has a poor electrical contact to the work piece then the connection point will heat up and result in a reduction of power at the arc.
Bent liner.	This will cause friction between the wire and the liner thus reducing wire feed.

Other weld problems can be reduced by checking the following points.

Troubleshooting - MIG Weld Quality
Fault	Cause	Remedy
Undercut.	Welding arc voltage too high.	Decrease voltage or increase the wire feed speed.
	Incorrect torch angle.	Adjust angle.
	Excessive heat input.	Increase the torch travel speed and/or decrease welding current by decreasing the voltage or decreasing the wire feed speed.
Lack of penetration.	Welding current too low.	Increase welding current by increasing wire feed speed and increasing voltage.
	Joint preparation too narrow or gap too tight.	Increase joint angle or gap.
Lack of fusion.	Voltage too low.	Increase voltage.
Excessive spatter.	Voltage too high.	Decrease voltage or increase the Current (Wire Speed) control.
	Voltage too low.	Increase the voltage or decrease Current (Wire Speed).
Irregular weld shape.	Incorrect voltage and current settings. Convex, voltage too low. Concave, voltage too high.	Adjust voltage and current by adjusting the voltage control and the Current (Wire Speed) control.
	Wire is wandering.	Replace contact tip.
	Incorrect shielding gas.	Check shielding gas.
	Insufficient or excessive heat input.	Adjust the Current (Wire Speed) control or the voltage control.
Weld cracking.	Weld bead is too small.	Decrease travel speed.
	Weld penetration narrow and deep.	Reduce current and voltage and increase MIG torch travel speed or select a lower penetration shielding gas.
	Excessive weld stresses.	Increase weld metal strength or revise design.
	Excessive voltage.	Decrease voltage.
	Cooling rate too fast.	Slow the cooling rate by preheating part to be welded or cool slowly.
Cold weld puddle.	Loose welding cable connection.	Check all welding cable connections.
	Low power supply voltage.	Contact supply authority.

Work Environment Safety

DANGER!

Remove any combustible material from the work area.

1. When possible, move the work to a location well away from combustible materials. If relocation is not possible, protect the combustibles with a cover made of fire resistant material.
2. Remove or make safe all combustible materials for a radius of 10 metres around the work area. Use a fire resistant material to cover or block all doorways, windows, cracks, and other openings.
3. Enclose the work area with portable fire resistant screens. Protect combustible walls, ceilings, floors, etc., from sparks and heat with fire resistant covers.
4. If working on a metal wall, ceiling, etc., prevent ignition of combustibles on the other side by moving the combustibles to a safe location. If relocation of combustibles is not possible, designate someone to serve as a fire watch, equipped with a fire extinguisher, during the welding process and well after the welding is completed.
5. Do not weld or cut on materials having a combustible coating or combustible internal structure, as in walls or ceilings, without an approved method for eliminating the hazard.

6. After welding, make a thorough examination for evidence of fire. Be aware that visible smoke or flame may not be present for some time after the fire has started. Do not weld or cut in atmospheres containing dangerously reactive or flammable gases, vapours, liquids, and dust. Provide adequate ventilation in work areas to prevent accumulation of flammable gases, vapours, and dust.

7. Do not apply heat to a container that has held an unknown substance or a combustible material whose contents, when heated, can produce flammable or explosive vapours. Clean and purge containers before applying heat. Vent closed containers, including castings, before preheating, welding, or cutting.

Electricity Can Kill

DANGER!

Touching live electrical parts can cause fatal shocks or severe burns. The electrode and work circuit is electrically live whenever the output is on.

The input power circuit and machine internal circuits are also live when power is on. In semi-automatic or automatic wire welding, the wire, wire reel, drive roll housing, and all metal parts touching the welding wire are electrically live. Incorrectly installed or improperly grounded equipment is a hazard.

1. Do not touch live electrical parts.
2. Wear dry, hole-free insulating gloves and body protection.
3. Insulate yourself from the work and the ground using dry insulating mats or covers.
4. Disconnect input power before installing or servicing this equipment. Lock input power, disconnect switch open, or remove line fuses so power cannot be turned on accidentally.

Arc rays from the welding process produce intense heat and strong ultraviolet rays that can burn eyes and skin. Use the following table to select the appropriate shade number for a Welding Helmet or Welding Face Shield.

1. Use a Welding Helmet or Welding Face Shield fitted with a proper shade of filter (see AS 60974-1, AS/NZS 1337.1 and AS/NZS 1338.1 Safety Standards) to protect your face and eyes when welding or watching.
2. Wear approved safety glasses. Side shields are recommended.
3. Use protective screens or barriers to protect others from flash and glare; warn others not to watch the arc.
4. Wear protective clothing made from durable, flame-resistant material (wool and leather) and foot protection.
5. Never wear contact lenses while welding.

Fumes And Gases

WARNING!

Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your health.

1. Keep your head out of the fumes. Do not breathe the fumes.

2. If inside, ventilate the area and/or use an exhaust at the arc to remove welding fumes and gases.

3. If ventilation is poor, use an approved air-supplied respirator.

4. Read the Safety Data Sheets (SDS) and the manufacturer's instruction for the metals, consumables, coatings, and cleaners.
5. Work in a confined space only if it is well ventilated, or while wearing an air-supplied respirator. Shielding gases used for welding can displace air causing injury or death. Be sure the breathing air is safe.
6. Do not weld in locations near degreasing, cleaning, or spraying operations. The heat and rays of the arc can react with vapours to form highly toxic and irritating gases.
7. Do not weld on coated metals, such as galvanized, lead, or cadmium plated steel, unless the coating is removed from the weld area, the area is well ventilated, and if necessary, while wearing an air-supplied respirator. The coatings and any metals containing these elements can give off toxic fumes if welded.

Fire & Explosive Risks

WARNING!

Sparks and spatter fly off from the welding arc. The flying sparks and hot metal, weld spatter, work piece, and hot equipment can cause fires and burns.

Accidental contact of electrode or welding wire to metal objects can cause sparks, overheating, or fire.

1. Protect yourself and others from flying sparks and hot metal.
2. Do not weld where flying sparks can strike flammable material.
3. Remove all flammables within 10m of the welding site.
4. Be alert that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas.
5. Watch for fire, and keep a fire extinguisher nearby.
6. Be aware that welding on a ceiling, floor, bulkhead, or partition can cause fire on the hidden side.

7. Do not weld on closed containers such as tanks or drums.

8. Connect the work lead/clamp to the job as close to the welding area as practical to prevent welding current from traveling long, possibly unknown paths and causing electric shock and fire hazards.

9. Do not use a welder to thaw frozen pipes.
10. Remove the stick electrode from the holder or cut off the welding wire at the contact tip when not in use.

Sparks & Hot Metal

WARNING!

Chipping and grinding causes flying metal, and as welds cool they can throw off slag.

1. Wear an AS/NZS approved face shield or safety goggles. Side shields are recommended.
2. Wear appropriate safety equipment to protect the skin and body.

Cylinders

WARNING!

Gas cylinders contain gas under high pressure. If damaged, a cylinder can explode. Since gas cylinders are normally part of the welding process, be sure to treat them carefully.

1. Protect compressed gas cylinders from excessive heat, mechanical shocks, and arcs.
2. Install and secure cylinders in an upright position by chaining them to a stationary support or equipment cylinder rack to prevent falling or tipping.
3. Keep cylinders away from any welding or other electrical circuits.
4. Never allow a welding electrode to touch any cylinder.
5. Use appropriate shielding gas, regulators, hoses, and fittings designed for the specific application; maintain them and their associated parts in good condition.
6. Turn your face away from the valve outlet when opening the cylinder valve.
