This will blow out dust or dirt that may have accumulated around valve seat. 2. Install regulator onto cylinder valve. Tighten stem nut securely to gas valve. 3. Install one end of gas hose to fitting on the back of welder and other end of hose to fitting on regulator. Make sure gas hose is not kinked or twisted. 4. While standing opposite cylinder outlet, slowly open cylinder valve. Inspect for leaks in the connections. 5. Turn unit on and pull trigger on torch to allow gas to flow. Adjust gas regulator to between 20 and 40 CFH. Release trigger and turn unit off. 6. Remember to close gas cylinder valve when finished welding. 6 Figure 6 - Polarity control Ground cable Brass nuts Drive deck cable Positive stud Negative stud NOTE: Electrode negative polarity (typical for flux core welding) shown in figure. Reverse cables for electrode positive polarity (typical for MIG welding). Models WG3080, WG3090 and WG4130 Operation 1. Be sure to read, understand and comply with all precautions in the General Safety Information section. Be sure to read entire MANUAL “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. 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 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. 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. 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- 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. 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 - .035" (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. 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. 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. Supply Cable Replacement 1. Verify that welder is OFF and power cord disconnected. 2. Remove welder side...
