NOTICE:
Over time, pressure on the drive rolls causes metal fragments from the ller wire’s surface to nd its way to the gun cable liner. If the wire guide is
not cleaned, it can gradually clog up and causes wire feed malfunctions.
If feeding difculty is observed, clean the liner in the following manner:
1. Remove the welding gun’s gas nozzle, contact tip and contact tip’s adapter.
2. With an air nozzle blow compressed air through the wire guide. Wear eye protection!
3. Blow out the wire feed mechanism and reel housing with dry compressed air.
4. Reassemble components. Tighten the contact tip and contact tip’s adapter with the spanner included to ensure tightness. Do not overtighten
any ttings or stripping of the threads may result.
The MIG torch liner may eventually become worn and will need to be replaced. When welding aluminum with the main gun, a Teflon liner must
be used, necessitating a liner change. A spool gun is the preferred method to weld Al, but a polymer liner may be used with guns 10ft and under
to weld aluminum. In this case, you will need to change the standard liner intended for steel use to feed directly from the machine.
To change the liner:
1. Remove the securing nut of the liner (#17) which exposes the end of the wire guide.
2. Straighten the gun cable and withdraw the liner from the gun.
3. Carefully push a new wire guide in to the gun. Make sure that the wire guide travels all the way to the contact tip.
4. Make sure the O-ring at the machine-end of the gun is installed
5. Tighten the wire guide in place.
6. Cut the liner 2mm from the mounting nut and le the sharp edge of the liner.
7. Reattach the gun and tighten all parts.
8. Re-thread wire.
