1 Connect the gas hose to the regulator and the rear of the machine. Select
correct shielding gas for the application.
2 Insert the work return lead connection into the front panel.
3 Fit the wire spool to the machine. Select correct welding wire for
application.
4 Select the appropriate feed roller to suit the wire being used.
This machine comes complete with three styles of wire feed rollers
-
V groove for use with solid carbon manganese and stainless steels
-
U groove for use with soft wires such as aluminium
-
Knurled rollers for flux cored wire.
5 Loosen the wire feed tension screws and insert the wire. Re fit and
tension rollers ensuring the wire is gripped sufficiently so as not to slip
but avoid over tightening as this can affect feed quality and cause wire
feed components to wear rapidly.
6 Fit and tighten the torch on the output connection
liner and contact tip are selected.
7 Select the correct polarity for the type of wire used as indicated on the
consumable packaging. This is achieved by swapping the polarity terminal
wires. For most solid wires the terminal should be set as torch positive.
