ConsumaBle and wear parts
The following parts require replacement:
•
Wire feed drive roller
•
Wire guide
•
Torch liner
•
Nozzle/contact tips
•
Wire - This welder will accept either 4 in. or 8 in. diameter
spools. Flux-Cored welding wire is susceptible to moisture
and oxidizes over time, so it is important to select a spool
size that will be used within approximately 6 months. For
mild steel welding, AWS ER70S6 solid wire or AWS E71T-GS
Flux-Cored wire is recommended.
CHanging wire sizes
This welder is setup for .030 in. (0.8 mm) wire. If a different wire
size is used, the wire feed drive roller and contact tip may need
changing. There are two grooves in the drive roller. The small
groove is for .024 in. (0.6 mm) MIG wire and the large groove is
for .030 - .035 in. (0.8 - 0.9 mm) flux core and MIG wire. Rotate
the tension knob down and swing arm up and flip the drive roller
to choose the correct groove. Optional drive rollers for other
wire sizes are available (See parts breakdown). The contact tip
should also match the wire diameter used. The tip diameter is
marked on the contact tip in inches and/or millimeters.
