is on and fan works.
* Set the welding mode button on MIG
* Turn on the gas regulator on the gas cylinder, the gas pressure is shown on the gauge.
* Release the drive roll pressure, press the gun trigger, and then adjust the gas flow to meet the
specification requirement, (turn the gas regulator anticlockwise to reduce the flow rate). Then
re-engage the drive roll pressure.
* Press the gun trigger till the wire exits the nozzle. (The nozzle may need to be removed from the
gun to allow this function).
* When wire feeding, keep the gun cable straight.
* When wire feeding, make sure the wire is located on the drive roll groove and the feeding speed
should be smooth. If the wire feeding speed is not smooth, please adjust the tension of the drive
roll.
* When using MIG wire, the V groove wire roller should be used.
b) Welding
* Follow welding guide on inside cover to set wire feed speed and volts to suit material thickness
wire diameter.
* Inductance can be adjusted for hard or soft welding arc
* Point the wire into the joint to be welded, press the gun trigger, the wire feeds automatically. The
arc is started once the wire touches the work piece.
