3. Place the spool onto the spindle so that the wire unwinds in an anti-clockwise direction.

4. Replace the spool plate and spring, then lock it in place with the spool nut.

5. Flip the tension adjustor bar up and swing the pressure arm away from the roller guide.

6. While maintaining a firm hold of the wire end, pull it free of the spool and thread it through the feed tube and into the cable housing.

7. Rotate the pressure arm back into place and flip the tension adjustor bar back to lock it in place.

WARNING! THE POWER SUPPLY FOR THIS PRODUCT SHOULD BE PROTECTED BY A RESIDUAL CURRENT DEVICE (RATED AT 30mA OR LESS). A RESIDUAL CURRENT DEVICE REDUCES THE RISK OF ELECTRIC SHOCK.

Loading The Torch

1. Twist the shroud clockwise and pull it off the torch, then unscrew the torch tip.
   Note: The 0.8mm torch tip is fitted by default. Swap it for the included 0.9mm tip if a different welding wire is used instead.

2. Place the earth clamp out of the way, away from the torch and welder unit on a nonconductive surface such as a wooden workbench. THERMAL OVERLOAD ALLOWS THE WELDER TO COOL DOWN VOLTAGE MIN MAX FEED RATE 100A INVERTER MIG WELDER MIN MAX
   WARNING! ENSURE THAT YOU DO NOT MAKE CONTACT WITH THE EARTH CLAMP AT ANY STAGE WHEN FEEDING THE WIRE THROUGH THE TORCH. THE ELECTRODE WIRE WILL BE AT WELDING VOLTAGE WHILST IT IS FED THROUGH. KEEP THE TORCH AWAY FROM YOUR EYES & FACE.

3. Plug the power cord into a power supply and flip the on/off switch to the on position.

4. Ensure the torch lead is straight as you depress the trigger to feed the wire through.

5. Once the wire protrudes from the end of the torch, release the trigger.

6. Hold the torch 2 to 3 inches away from a non-conductive hard surface and depress the trigger. If the wire stops against the surface without bending, switch off the welder and tighten the feed tensioner slightly by turning it clockwise.

7. The tension is correctly set if the wire fed through the torch bends when it encounters the hard surface. Repeat step 6 until this happens.

8. Switch the welder off.

9. Fit the appropriate torch tip by screwing it on clockwise. Push and twist the shroud clockwise as well to fit it on the torch.
   WARNING! ONLY USE THE 0.8MM TIP WITH 0.8MM WELDING WIRE OR THE 0.9MM TIP WITH 0.9MM WIRE. INCORRECT TIP USAGE CAN CAUSE SPOOLING ISSUES & DAMAGE THE MACHINE.

10. Leave 10mm protruding from the end of the torch and cut off any excess welding wire.
    Note: Do not cut the wire at an angle. The end of the welding wire should be flat and have no burrs or sharp edges. File down the end or cut it again if necessary

Welding Wire Settings Selection
There are many variables that you will need to take into account when choosing your welding wire size and type. Below are some of the factors that should be considered:

WIRE
DIAMETER| SUGGESTED
SETTINGS| STEEL THICKNESS (MM)
---|---|---
1.2| 1.5| 2| 3
0.8mm| Voltage| 2-Jan| 3-Feb| 6-Apr| 10-Jul
Wire Speed| 2-Jan| 3-Feb| 7-Apr| 10-Aug
0.9mm| Voltage| –| 2-Jan| 6-Mar| 10-Jul
Wire Speed| –| 5-Apr| 6-May| 7-Jun

Note: The above chart is only intended as a general guide. Proper welding will also depend on how close the torch is held to the material and the speed it is moved along the weld. Always test new settings on a scrap piece of material first. Proper welding takes good technique and practice.

Aluminum Welding
For aluminum welding, the aluminum wire must be used. The workpiece must be thoroughly cleaned with a stainless steel wire brush to remove oxides and impurities from the weld surface.
Depending on the thickness of the workpiece, it also may require additional heat sinks to be attached to the workpiece. Ensure proper tip-to-work distance to prevent the wire from burning back to the contact tip.

CONTROLS

WARNING! ENSURE APPROVED PROTECTIVE CLOTHING & A WELDING HELMET/MASK IS WORN AT ALL TIMES TO PROTECT YOUR FACE & EYES FROM ARC UV RADIATION & SPARKS.

ON/Off Switch
The on/off switch is located on the rear of the welder.

1. Press the on/off switch into the on position ‘I’ to switch the unit on.

2. To switch the unit off, press the switch to the ‘0’ position.

Note: Check the rating of the circuit breaker on the supply and other appliances connected to the circuit. The welder is a high-powered device and it is recommended that it is the only appliance on the circuit to ensure it has enough power to operate.
Note: If a 15A circuit is available, it is recommended that the welder be connected to this.

WARNING! DO NOT LEAVE THE SWITCH IN THE ON POSITION WHEN THE UNIT IS NOT IN USE AS THIS POSES THE RISK OF ELECTROCUTION OR ACCIDENTS HAPPENING TO THE NEXT USER.

Wire Feed Speed
The wire feed speed should be adjusted to suit the application and material being welded. Refer to the Welding Wire Settings Selection Table as a guide.
Note: Always test settings on a scrap piece of material first.

Variable Voltage
The voltage should be set according to the application, material being welded, and wire feed speed.

1. The voltage can be increased or decreased by turning the voltage control dial.

INDICATOR LEDS

WARNING! IF THE WELDER OVERHEATS & THE THERMAL OVERLOAD PROTECTION ENGAGES, DO NOT TURN OFF THE WELDER AS THE FAN WILL ASSIST IN SPEEDING UP THE COOLING TIME.
WARNING! ENSURE THE CLAMP & THE TORCH IS AWAY FROM THE WELDING MATERIAL & PLACED ON A NON-CONDUCTIVE SURFACE WHILE THE OVERLOAD PROTECTION IS ENGAGED.

Power LED Light

1. The ON LED illuminates when the power cord is connected to a live mains outlet and the on/off switch is in the on position.
   Note: The cooling fan will operate when the unit is switched on.

Thermal Overload Protection
All Welders have a feature called a duty cycle. The 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 a 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 to cool down so you can return to your welding job.
Duty cycle % as referenced on the rating label is 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.

WELDING

Welding

1. Ensure that the workpiece is clamped down securely, is cleaned, and prepared for welding.

2. Attach the earth clamp to the workpiece ensuring there is good metal-to-metal contact.
   Note: Prior to connecting the earth clamp it may be necessary to clean the surface of the workpiece using the metal brush. Clamp it where it will not be in the way. This clamp provides an earth connection back to the welder.

3. Switch the welder on and position the welding mask in front of your eyes.

4. Position the wire tip approximately 8mm from the workpiece at a 20° angle from the vertical in the direction of movement.

5. Squeeze the torch trigger to start the weld.

Welding Tips
Travel Speed
There are a range of welding movements used in welding. Generally, some form of zig-zag motion is used to ensure the arc acts against both sheets to be welded. The torch should be moved along at a smooth speed that will give the size of run required. At the same time, the wire is fed downwards to keep the correct welding distance at all times.
Excessive travel speeds lead to poor fusion and lack of penetration. While too slow the rate of travel may damage the workpiece and can lead to burning a hole through the material.

Electricity
The electricity flows through the wire and will not leave the wire unless it is near an earthed object. Electricity always finds the fastest path to the earth. When the earth cable clamp is connected to the metal workpiece a direct earth connection is created back to the welder. When the wire touches or is near the earthed workpiece when the trigger is squeezed, electricity flows through the wire, the metal workpiece, and then through the earth cable straight back to the welder.

TROUBLESHOOTING

WARNING! THE WELDER SHOULD ONLY BE SERVICED BY QUALIFIED PERSONNEL.
