Welding operation
Once you have set machine up as per above instructions.
Operating in Mig Mode
1.
Fit wire reel onto wire feed unit
2.
Inch wire to end of torch tip using ‘Inch’ button on wire feed unit
3.
Select welding voltage (power) required on wire feed unit
Note: Welding voltage preset can be viewed in Voltage LED on front panel of machine
4.
Select wire feed speed required on ‘Welding Current’ knob on wire feed unit
5.
Select either 2T or 4T operation switch in desired position
6.
Set ARC force switch to middle position for medium weld inductance (know as choke
on traditional welding power sources)
Low setting = Soft ARC (less splatter & penetration)
High setting = Strong ARC (more penetration)
7.
Press torch trigger to start welding process and adjust welding current knob to adjust
wire feed accordingly.
Note: You can finely adjust the welding current knob to fine tune weld arc length to
either DIP or SPRAY welding
8.
When welding actual voltage and amperage will be shown in corresponding LED
display meters on machine
Operating in MMA Mode
Select welding amperage required on current control knob on front panel of welder, select MMA
mode on switch no.10, welding terminals are now constantly live, machine is now ready to weld.
Once you have finished weld either turn machine off or switch back into mig mode so terminals
are not live.
