Several changes are needed to convert the unit for
operation with the MIG (GMAW) process. The follow-
ing conversions should be reviewed before welding
with (GMAW):

1. Change the output polarity to DC(+). See

“

Work

Cable Installation

in Installation section for details.

2. Install proper drive roll for the wire size selected.

See

“

3. Install the proper gun liner and tip for the wire size

selected. See

“

Component Replacement

”

in

Maintenance section for details.

4. Remove gasless nozzle (if installed) and install gas

nozzle.

5. Load wire into machine and thread into gun and

cable per
