Installation

Location

Selecting the proper location can significantly increase performance, reliability and life of the arc welder.

• For best results locate the welder in an environment that is clean and dry. Dust and dirt in the welder retain moisture and increase wear of moving parts.

• Store electrodes in a clean, dry location with low humidity to preserve the flux coating.
  The receptacle used for the welder must be properly grounded and the welder must be the only load on the power supply circuit. Refer to the Circuit Amps chart on page 1 for correct circuit capacity.
  The use of an extension cord is not recommended for arc welding machines. Extension cord use will significantly degrade the performance of the welder.

Welding Guidelines

General

This welding machine utilizes a process known as Shielded Metal-Arc Welding (SMAW). This process is used to bond metals by heating them with an electric arc created between the electrode and the work piece.

Electrodes used for shielded metal arc welding have two parts. The inner core is a metal rod or wire that should be similar in composition to the base metal. The outer coating is called flux. Various types of flux exist. Each coating is used for a particular welding situation.

While the metal is molten, it can be contaminated by elements in the air. This contamination could weaken the weld. The flux coating creates a protective barrier called slag that protects the molten metal from contaminants.

When current (amperage) flows through the circuit to the electrode, an arc is formed between the end of the electrode and the work piece. The arc melts the electrode and the work piece. The melted metal of the electrode flows into the molten crater and forms a bond with the work piece as shown in Figure 6.

NOTE: Discontinue using and discard electrodes that burn down to 1 to 2 inches from the electrode holder.

STRIKING AN ARC

Attach work clamp to work piece. The jaws of the work clamp must make good contact with clean bare metal of the work piece for good welding results.

Place the bare end of the electrode in the holder. Grip the holder lightly to reduce tiring of the hand and arm.

NOTE: Always keep the jaws of the holder clean to ensure good electrical contact with the electrode.

Be careful not to touch the work

piece or welding bench with the electrode as this causes arc flashes.

The best method of striking an arc is the scratching method. Drag the electrode at an angle along the surface much like striking a match. Upon contact with the plate, lift the electrode approximately 1/16 in. off the surface or it will stick (See Figure 7).

Figure 7 - Scratching Method

NOTE: Should the electrode stick to the work piece, break it loose by quickly twisting or bending at the holder while pulling upward. If the electrode does not break loose, disengage the electrode by releasing it from the holder.

ELECTRODE TYPE AND SIZE

Two types of electrodes are recommended for this welder. The electrodes are commonly known by the AWS (American Welding Society) designation as follows:

1. E-6013 GENERAL PURPOSE

• All position, smooth deposit rod with low spatter.
• For all mild steel and general purpose work.

2. E-7014 FAST FILL

• Smooth bead and fast deposition
• Ideal for joints with poor fitup and general repair work

NOTE: E-6011 and E-7018 are not recommended for use with these welders. Recommended electrode diameter is 1/16 in. or 5/64 in.. Call [phone] for availability.

Arc Welding Basics

Four basic techniques affect weld quality. These are: amperage setting, weld angle, arc length, and travel speed. Proper use of these techniques is necessary for good weld quality.

AMPERAGE SETTING

The correct amperage involves the adjustment of the welding machine to the required amp setting. This is regulated by selecting the appropriate high or low setting. The amperage required depends on the size (diameter) of electrode used and the thickness of the work piece.

Excessive currents burn through light metals and the weld bead is flat and porous (See Figure 9). The bead appears high and irregular if the current is too low.

WELD ANGLE

Weld angle is the angle at which the electrode is held during the welding process. Using the correct angle ensures proper penetration and bead formation. Electrode angle involves two positions - travel angle and work angle (See Figure 8).

Travel Angle

Work Angle
Figure 8 - Weld Angle

Travel angle is the angle in the line of welding and may vary from 5^ to 45^ from the vertical, depending on welding conditions.

Work angle is the angle from horizontal, measured at right angles to the line of welding.

Welding Guidelines (Continued)

Figure 9 - Weld Appearance
Arc Length Too Short

For most applications, a 45^ travel angle and 45^ work angle is sufficient. For specific applications, consult an arc welding handbook.

NOTE: Right handed welders should weld from left to right. Left handed welders should weld from right to left. The electrode should always point into the weld puddle as shown.

ARC LENGTH

Arc length is the distance from the work piece to the tip of the electrode, the distance which the arc must travel. A proper arc length is essential to generate the heat needed for welding (See Figure 9). An arc that is too long produces an unstable arc, reduces penetration, increases spatter, and causes flat and wide beads. Too short an arc does not create enough heat to melt the work piece, the electrode has a tendency to stick, penetration will be poor, and uneven beads with irregular ripples result. A proper arc should be no longer than the diameter of the rod. The sound of a proper arc is a steady, crisp sizzle, similar to bacon frying.

TRAVEL SPEED

The travel speed is the rate at which the electrode is moved across the weld area (See Figure 9). When the speed is too fast, the bead is narrow and bead ripples are pointed as shown. When the speed is too slow, the weld metal piles up and the bead is high and wide. To control travel speed, watch the width of the weld bead (not the arc) when welding. The weld bead is the orange, molten metal behind the arc. The width should be approximately twice the diameter of the welding rod. Control travel speed to obtain a consistent bead width.

SLAG REMOVAL

WARNING Wear ANSI approved safety glasses (ANSI Standard Z87.1) and protective clothing when removing slag. Hot, flying debris can cause personal injury to anyone in the area.

After completing the weld, wait for the welded sections to cool. A protective coating called slag now covers the weld bead which prevents contaminants in the air from reacting with the molten metal. Once the weld cools to the point that it is no longer glowing red, the

slag can be removed. Removal is done with a chipping hammer. Lightly tap the slag with the hammer and break it loose from the weld bead. The final clean-up is done with a wire brush. When making multiple weld passes, remove the slag between each pass.

WELDING POSITIONS

Four basic welding positions can be used; flat, horizontal, vertical, and overhead. Welding in the flat position is easier than any of the others because welding speed can be increased, the molten metal has less tendency to run, better penetration can be achieved, and the work is less fatiguing.

Other positions require different techniques such as a weaving pass, circular pass, and jogging. A higher skill level is required to complete these welds.

All work should be performed in the flat position if possible. For specific applications, consult an arc welding handbook.

Welding Guidelines (Continued)

WELD PASSES

Sometimes more than one pass is necessary to fill the joint. The root pass is first, followed by filler passes and the cover pass (See Figure 10). If the pieces are thick, it may be necessary to bevel the edges that are joined at a 60^ angle. Remember to remove the slag between each pass.

Notes

Glossary of Welding Terms

AC or Alternating Current - electric current that reverses direction periodically. Sixty cycle current travels in both directions sixty times per second.

Arc Length - the distance from the end of the electrode to the point where the arc makes contact with the work surface.

Base Metal - the material to be welded.

Butt Joint - a joint between two members aligned approximately in the same plane.

Crater - a pool, or pocket, that is formed as the arc comes in contact with the base metal.

DC or Direct Current - electric current which flows only in one direction. The polarity (+ or -) determines which direction the current is flowing.

DC Reverse Polarity - occurs when the electrode holder is connected to the positive pole of the welding machine. Reverse Polarity directs more heat into melting the electrode rather than the work piece. It is used on thinner material.

DC Straight Polarity - occurs when the electrode holder is connected to the negative pole of the welding machine. With straight polarity more heat is directed to the work piece for better penetration on thicker material.

Electrode - a coated metal wire having approximately the same composition as the material being welded.

Fillet Weld - approximately a triangle in cross-section, joining two surfaces at right angles to each other in a lap, T or corner joint.

Flux - the coating on arc-welding rods and in flux-cored welding wire that is consumed in the arc to produce a shielding gas. This gas displaces air and impurities from around the weld.

Flux Cored Arc Welding (FCAW) - also called Gasless, is a welding process used with a wire-feed welding machine. The weld wire is tubular with flux material contained inside for shielding.

Gas Metal Arc Welding (GMAW) - also called MIG, is a welding process used with a wire feed welding machine. The wire is solid and an inert gas is used for shielding.

Gas Tungsten Arc Welding (GTAW) - also called TIG, is a welding process used with welding equipment with a high frequency generator. The arc is created between a non-consumable tungsten electrode and the work piece. Filler metal may or may not be used.

Lap Joint - a joint between two overlapping members in parallel planes.

Open Circuit Voltage (OCV) - the voltage between the electrode and the work clamp of the welding machine when no current is flowing (not welding). The OCV determines how quickly the arc is struck.

Overlap - occurs when the amperage is set too low. In this instance, the molten metal falls from the electrode without actually fusing into the base metal.

Porosity - gas pockets, or cavities, formed during weld solidification. They weaken the weld.

Penetration - the depth into the work piece that has been heat effected by the arc during the welding process. A good weld achieves 100% penetration meaning that the entire thickness of the work piece has been heated and resolidified. The heat effected area should be easily seen on the opposite side of the weld.

Shielded Metal Arc Welding (SMAW) - also called Stick, is a welding process with uses a consumable electrode to support the arc. Shielding is achieved by the melting of the flux coating on the electrode.

Slag - a layer of flux soot that protects the weld from oxides and other contaminants while the weld is solidifying (cooling). Slag should be removed after weld has cooled.

Spatter - metal particles thrown from the weld which cool and harden on the work surface. Spatter can be minimized by using a spatter resistant spray on the work piece before welding.

Tack Weld - weld made to hold parts in proper alignment until final welds are made.

Travel Angle - the angle of the electrode in the line of welding. It varies from 5^ to 45^ depending on welding conditions.

T Joint - made by placing the edge of one piece of metal on the surface of the other piece at approximately a 90^ angle.

Undercut - a condition that results when welding amperage is too high. The excessive amperage leaves a groove in the base metal along both sides of the bead which reduces the strength of the weld.

Weld Pool or Puddle - a volume of molten metal in a weld prior to its solidification as weld metal.

Weld Bead - a narrow layer or layers of metal deposited on the base metal as the electrode melts. Weld bead width is typically twice the diameter of the electrode.

Work Angle - the angle of the electrode from horizontal, measured at right angles to the line of welding.
