8.1 MIG Welding Set-up
1 Ensure the machine is correctly plugged into the main circuit
2 Proper PPE must be worn
3 Ensure workplace safety such as fume extraction is in place
4 Switch machine on using On/O󹟽 switch at the back of the machine
5 Open gas cylinder and set gas ow rate
6 Set voltage and wire feed speed (the tables included in this manual
can be used as a guideline for voltage and wire speed selection)
7 Voltage is set by adjusting voltage knob (1) on powersource
8 Wire feed speed can be set independently by adjusting the wire feed
speed/Arc current knob(2)
9 Inductance can be changed by adjusting the inductance knob (3) on
the power source
10 Welding wire can be fed through the torch by selecting “Wire Inch”
button located inside the power source above the wire feeder.
11 For certain types of self shielded ux cored wires it is required to
change the polarity. This can be achieved by switching the work
return lead and clamp from the negative dinse connector(5) to the
positive dinse connector (4). The pigtail needs to then change from
the positive dinse connector (4) to the negative dinse connector(5).
8.2 MMA Welding Set-up
1 Ensure the machine is correctly plugged into the main circuit
2 Proper PPE must be worn
3 Ensure workplace safety such as fume extraction is in place
4 Switch machine on using On/O󹟽 switch at the back of the machine
5 Select process by depressing the process selection switch (7) toMMA
6 Fit work return lead to negative dinse*
7 Fit electrode holder to positive dinse connector*
8 Select Amperage by turning by wire feed speed/Arc current knob(2)
*
DCEP Connection. For DCEN when recommended by the
consumable supplier, reverse the terminals as stated in
points6 & 7.
