Models WG3080, WG3090 and WG4130
Operation
1. Be sure to read, understand
and comply with all
precautions in the General MANUAL Safety Information section.
Be sure to read entire
“Welding Guidelines” section before using this equipment.
2.Turn welder off.
3.Verify surfaces of metals to be joined are free from dirt, rust, paint, oil, scale or other contaminants. These contaminants make welding difficult and cause poor welds.
All persons operating this equipment or in the area while equipment is in use must wear protective welding gear including: eye protection with proper shade, flame resistant clothing, leather welding gloves and full foot protection.
If heating, welding or cutting galvanized, zinc plated, lead,
or cadmium plated materials, refer to the General Safety Information Section for instructions. Extremely toxic fumes are created when these metals are heated.
4.Connect work clamp to work piece or workbench (if metal). Make sure contact is secure. Avoid surfaces with paint, varnish, corrosion or non- metallic materials.
5.Rotate Wire Speed Control to setting per decal inside wire feed compartment, then adjust as needed after test.
6.Plug power cord into a proper voltage receptacle with proper circuit capacity (see circuit requirements on Page 1).
7.Switch welder on to desired heat setting per decal inside wire feed compartment, then adjust as needed after test.
NOTE: These settings are general guidelines only. Heat setting may vary according to welding conditions and materials.
8.Verify wire is extended 1/4" from contact tip. If not, squeeze trigger to feed additional wire, release trigger, turn welder off, and cut wire to proper length. Then, switch back on to desired heat setting.
9.Position torch near work piece, lower welding helmet by nodding head or positioning the hand shield, and squeeze torch trigger. Adjust heat setting and wire speed as needed.
10.When finished welding, turn welder off and store properly.
Maintenance
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.
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.
Do not operate
this welding machine with cracked or missing insulation on welding cables, torch 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 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
•Wire guide
•Torch liner
•Nozzle/contact tips
•Wire - This welder will accept either 4" or 8" diameter spools.
CHANGING WIRE SIZES
This welder is setup for .030" (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" (0.6 mm) MIG wire and the large groove is for .030
Supply Cable Replacement
1.Verify that welder is OFF and power cord disconnected.
2.Remove welder side panel to expose switches.
3.Disconnect the power cord leads per the diagram inside the unit.
4.Disconnect the ground wire connected to welder base.
5.Loosen the cord strain relief screws and pull cord out of strain relief.
6.Install new cord in reverse order per the diagram inside the unit.
