MAINTENANCE
Before Every Use:
1. Check condition of weld cables and immediately repair or replace any cables with damaged insulation.
2. Check condition of power cord and immediately repair or replace any cord if damaged.
3. Inspect the condition of the torch contact tip and nozzle. Remove any weld slag. Replace torch contact
tip or nozzle if damaged.
Every 3 Months:
1. Replace any unreadable safety labels on the welder.
2. Use compressed air to blow all dust and lint from ventilation openings.
3. Clean wire groove on drive roller. Remove drive roller and use a small wire brush to clean. Replace if
worn or damaged.
Consumable and Wear Parts
The following parts require replacement:
• Wire feed drive roller
• Torch liner
• Nozzle/contact tips
• Wire - This welder will accept either 4 inch or 8 inch 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 inch (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
inch (0.6 mm) MIG wire and the large groove is for .030 inch - .035 inch (0.8 mm - 0.9 mm) flux core and MIG
wire. Rotate the tension knob down and swing arm up. Remove roller support by removing two screws and
flip the drive roller to choose the correct groove. The contact tip should also match the wire diameter used.
The tip diameter is marked on the contact tip in inches and/or millimeters.
Disconnect power supply and turn machine off before inspecting or servicing any components.
Keep wire compartment cover closed at all times unless wire needs to be changed.
Do not operate this welding machine with cracked or missing insulation on welding cables,
torch or power cord.
SUPPLY CABLE REPLACEMENT
Verify that welder is OFF and power cord disconnected.
Remove welder side panel to expose switches.
Disconnect the power cord leads per the diagram inside the unit.
Disconnect the ground wire connected to welder base.
Loosen the cord strain relief screws and pull cord out of strain relief.
Install new cord in reverse order per the diagram inside the unit.
