Disconnect the welder from the mains.
Remove the side panel from the welder.
Loosen the earth lead cable gland.
Remove the torch connecting lead from the rectifier plate.
Remove the thermal overload lead and torch connection lead from the rectifier plate, (if the overload lead is
crimped into the same ring crimp as the PCB connecting lead cut the overload lead next to the crimp), do
not remove the feed motor power lead from the plate.
Extend the thermal overload lead by 450mm and pass it through the grommet in the centre panel.
Trim the lead so that it will reach the brass threaded section of the torch.
Fit a 10mm ring crimp to the end of the lead and fit this onto the brass threaded section of the torch.
Remove the crimp connection between the choke and the earth lead.
Clean the insulation from the choke lead for 40mm and form into a ring around a 6mm bolt.
Bolt the free end of the torch connecting lead to the newly form ring using the M6 nust bolts and washers.
Fit the 6mm crimp onto the end of the earth lead.
Pull the earth lead so that it reaches the rectifier plate at the point where the torch connecting lead was lo-
cated and bolt into place.
Tighten the earth lead cable gland.
Ensure all connections are tight and the internal cables are routed neatly, check they are not touching any
mains connection or hard against any sharp edges, you may need to use cable ties to secure the cables.
Refit cover.
The welder will now operate correctly with gasless wire but not solid wire, if solid wire is to be used the
polarity will have to be reversed again.
