Wire Feed Arc Welder
Operation (Continued)
See application decal inside door of wire feed compartment for proper heat settings.
NOTE: These settings are general guidelines only. Heat setting may vary according to welding conditions and materials.
6.Rotate the Wire Speed Control to setting number 5 to start with, then adjust as needed after test weld.
7.Plug the input cord into a proper voltage receptacle with proper circuit capacity (See Chart under circuit requirements on page 1).
8.Switch the welder ON.
9.Verify that the wire is extended 1/4” from the contact tip. If not, squeeze the trigger to feed additional wire, release the trigger, and cut wire to proper length.
10.Position the wire feed gun near the work piece, lower the welding helmet by nodding the head, or position the hand shield, and squeeze the gun trigger. Adjust heat setting and wire speed as needed.
11.When finished welding, turn welder off and store properly.
Maintenance
Disconnect power

3.Clean the wire groove on the drive roll. Remove wire from the feed mechanism, remove screws from the drive roll housing. Use a small wire brush to clean the drive roll. Replace if worn or damaged.
Consumer and Wear Parts
The following parts require routine maintenance:
•Wire feed drive roller
•Gun liner - replace if worn
•Nozzle/contact tips
•Wire - this welder will accept either 4” or 8” diameter spools. 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
•Contact tips - use Campbell Hausfeld, Tweco®, and other compatible tips.
•Nozzle - use Tweco® style or compatible nozzle. Use Campbell Hausfeld nozzle model WT5021 found at place of purchase of welder, or use Tweco® style nozzle (or compatible nozzle) found at local welding supply store.
MIG WIRE
Since MIG wire maintains fair wire diameter consistency, the contact tip used should match the wire size used. When using .024 (.6 mm) wire, use the small groove on the drive roller. When using .030
ALUMINUM WIRE
When using Aluminum wire, it is best to use a larger size tip than the wire size being used. For example:
• If wire diameter is .030, use .035 tip.

servicing any components. Keep the wire compartment cover closed at all times unless the wire needs replacement.
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 gun tip and nozzle. Remove any weld slag. Replace gun tip or nozzle if damaged.
!WARNING Do not operate this welding machine
with cracked or missing insulation on welding cables, wire feed gun, or power cord.
Every 3 months:
1.Replace any unreadable safety labels on the welder.
2.Use compressed air to blow all dust and lint from the ventilation openings.

DRIVE ROLLER
There are two grooves in the Drive Roller. The small groove is for .024” (.6
mm)wire and the other is for .030” -
.035” (.8
FLUX CORE WIRE
Due to small inconsistencies in wire diameter, using one size larger tip is recommended. For example:
• If wire diameter is .030, use .035 tip.
• If wire diameter is .035, use .040 tip.
This welder is setup for .035 (.9 mm) wire and has a .040 tip. Since this welder uses .030 and .035 Flux Core Wire, the drive roller should be in its factory
