Frequently Asked Questions - IWR-120 Ozito

What is the duty cycle of the Ozito IWR-120?

The duty cycle is based on a 10-minute period. At 120A (maximum), it is 20% meaning you can weld for 2 minutes then must cool for 8 minutes. At 69A it is 60% (6 min welding), and at 54A it is 100% (10 min continuous). The cooling fan runs even when the welder is off to aid cooling.

How do I strike an arc with this welder?

Lower the electrode slowly and strike the tip against the workpiece like striking a match. Once the arc starts, maintain a gap equal to the electrode diameter (e.g., 2.0mm electrode = 2.0mm gap). Use proper protective gear and ensure good electrical contact.

Why does my welder shut off during use?

This is likely due to the thermal overload protection. If the Thermal Overload LED is on, the welder has overheated. Do not turn it off; the internal fan will cool it down. Cooling may take up to 10 minutes. This is normal in heavy use and does not indicate a fault.

What electrodes should I use and what current setting?

Use arc welding electrodes (MMA) with diameters 1.6-3.2mm. For 2mm electrodes, set current 30-60A; for 2.5mm, 50-80A; for 3.2mm, 90-120A. Adjust based on steel thickness and electrode type. Always store electrodes dry.

How do I set the welding current?

Turn the Welding Current Control knob on the front panel. The digital display shows the selected current. Increase for thicker material or larger electrodes; decrease for thinner material or smaller electrodes.

What safety precautions must I take?

Always wear a welding mask with proper glass filter, protective clothing (leather apron, gloves), and avoid skin exposure to UV rays. Ensure good ventilation, remove flammable materials, and use a residual current device (RCD) rated 30mA or less. Disconnect power before changing electrodes.

How do I connect the cables?

Attach the arc electrode holder to the positive (+) terminal and the earth clamp to the negative (-) terminal. Insert and rotate clockwise until firm. Ensure good metal-to-metal contact at the earth clamp on a clean area.

Why is my arc spluttering or the electrode sticking?

Spluttering often indicates an arc that is too long. Shorten the arc length. Sticking may be due to low current or incorrect electrode angle. Increase current slightly and maintain a 5-15 degree angle in the direction of travel. Ensure electrodes are dry.

How do I maintain the welder?

Keep the welder clean and dry. Check cables for damage before each use. Store electrodes in a dry place. The cooling fan should operate freely. For repairs, contact qualified personnel. Do not open the housing.

What is covered under the 3-year warranty?

The 3-year replacement warranty covers defects in materials or workmanship. It does not cover consumable parts (welding tips, torch nozzles, welding wire, etc.), damage from abuse, incorrect voltage, or unauthorized modifications. Keep your Bunnings receipt.

Electrodes

Always store the electrodes in a dry place protecting them from moisture. Should electrodes become damp or moist, bake them in an oven at 200 - 250°C for 2 hours. Unless the electrodes are vacuum packed, basic coated electrodes will always require such baking prior to use.

Metal arc welding electrodes consist of a core wire surrounded by a flux coating. The flux coating is applied to the core wire by an extrusion process. The coating on arc welding electrodes has a number of purposes:

• To provide a gaseous shield for the weld metal, and preserve it from contamination by the atmosphere whilst in a mol ten state.
- To give a steady arc by having 'arc stabilisers' present, which provide a bridge for current to flow across.
• To remove oxygen from the weld metal with 'deoxidised'.
• To provide a cleansing action on the work piece and a protective slag cover over the weld metal to prevent the formation of oxides while the metal is solidifying. The slag also helps to produce a bead of the desired contour.
• To introduce alloys into the weld deposits in special type electrodes.

Arc Length

To strike the arc, the electrode should be gently scraped on the work until the arc is established. A simple rule for the proper arc length; it should be the shortest arc that gives a good surface to the weld. A very long arc produces a crackling or spluttering noise and the weld metal comes across in large, irregular blobs and gives a rough surface finish to the weld. A short arc is essential if a high quality weld is to be obtained but a excessively short arc will cause sticking of the electrode and result in poor quality welds. For down hand welding is to have an arc length no greater than the diameter of the electrode.

Electrode Angle

The angle that the electrode makes with the work is important to ensure a smooth, even transfer of metal. When welding in down hand, fillet, horizontal or overhead the angle of the electrode is generally between 5 and 15 degrees towards the direction of travel. When vertical up welding the angle of the electrode should be between 70 and 80 degrees to the work piece.

Travel Speed

The electrode should be moved along in the direction of the joint being welded at a speed that will give the size of run required. At the same time, the electrode is fed downwards to keep the correct arc length at all times. Excessive travel speeds lead to poor fusion and lack of penetration. While too slow a rate of travel will frequently lead to arc instability, slag inclusions and poor mechanical properties.

Electricity

The electricity flows through the electrode cable to the attached electrode. The electricity will not leave the electrode unless it touches an earthed object.

Electricity always finds the fastest path to the earth. When the earth cable clamp is connected to the metal work piece a direct earth connection is created back to the welder. When the electrode makes contact with the earthed work piece an arc is created. The electricity flows through the electrode, the metal work piece and then through the earth cable straight back to the welder.

Earth Clamp

Prior to connecting the earth clamp it may be necessary to clean the surface of the work piece using the metal brush. Attach the earth clamp firmly to the work piece ensuring there is good metal to metal contact. Clamp it where it will not be in the way. This clamp provides an earth connection back to the welder. Always ensure the welder is disconnected from the power supply before attaching electrodes into the holder.

IMPORTANT INFORMATION

TROUBLESHOOTING

Thermal Overload

IF YOUR WELDER OVERHEATS AND THE THERMAL OVERLOAD PROTECTION ENGAGES DO NOT TURN YOUR WELDER OFF AS THE FAN WILL ASSIST IN REDUCING THE COOLING TIME.

All Welders have a feature called a duty cycle.

Duty cycle on a welder refers to the time in which the welder operates during normal welding.

A welder can only weld for a certain continuous period of time before it requires to cool down.

If the internal components of the welder should become hot the welder could overheat. If the welder overheats the Thermal Overload Protection feature will automatically shut down the welder.

THIS CAN OCCUR IN HEAVY USE AND DOES NOT INDICATE A FAULT.

The Welder will cease to weld and the Thermal Overload LED light will turn on. This LED indication light is just to inform you that your welder is becoming too hot and requires to cool down to protect the internal components of the welder. Do Not turn your welder Off as the welder has an internal cooling fan and this will assist your welder to cool down quicker. Reducing the cooling time will enable you to get back to your welding job quicker.

Depending on how many Amps or how heavy the welding you are doing the cooling time may take up to 10 Minutes for your welder cool down so you can return to your welding job.

Duty cycle % as referenced on the rating label are based on 10 minute intervals.

For instance with a 20% duty cycle, one can weld continuously for 2 minutes, but then must wait 8 minutes for the welder to cool. Lower current levels have longer duty cycles.

Important Information about Radio Electromagnetic Compatibility

Extra precautions for Electromagnetic Compatibility may be required when this Welding Power Source is used in a domestic situation.

It is the user's responsibility to install and use the equipment properly in accordance with the instructions issued by the manufacturer. If electromagnetic disturbances are detected then it shall be the responsibility of the user of the equipment to resolve the situation with the following guidelines.

Precautions to consider in the surrounding area that may cause/be affected by electromagnetic disturbances

- Other supply cables or signal cables in close proximity to the welding equipment

• Radio and television transmitters and receivers

• Computer or electronic equipment
• Personal medical devices (pacemakers and hearing aids)

Methods of reducing electromagnetic disturbances

- If interference occurs when the equipment is connected to the mains power supply in a residential (domestic) low voltage power network, an electromagnetic filter may be required.

- The Welding cables should not be modified and kept as short as possible.

- Nearby cables and equipment may need to be moved or shielded.

Fumes

Toxic gases are given off during the ARC welding process, which may collect in the welding area if the ventilation is poor. Be alert at all times to the possibility of fume build-up. In small or confined areas use a fume extractor.

Glare

The electric arc generated by the arc process gives direct heat and ultraviolet radiation. It is essential that the eyes of the operator and bystanders are protected from the glare during welding.

ALWAYS USE A FACESHIELD OR WELDING HELMET FITTED WITH THE CORRECT GLASS FILTER.

Position and Handling

Position the welding machine on a horizontal surface that is able to support the weight: otherwise (e.g. inclined or uneven floors etc.) there is danger of overturning.

The welder MUST NOT be supported by the operator (e.g using belts).

The operator MUST NOT BE ALLOWED to weld in raised positions unless safety platforms are used.

Heat

It is desirable that welding gloves are worn whilst welding. They will protect the hands from ultraviolet radiation and direct heat of the arc.

Dress

In addition to face shield, welding gloves and overalls, other types of protective clothing should be worn when welding. Additional protective clothing such as a leather apron, sock protectors and a hat will all assist in reducing any injuries due to heat, sparks and slag produced during welding. OVERALLS should also be worn. They should be of type designed to be buttoned at the wrists and the neck.
