MANUAL 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 nonmetallic 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 in. 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 • 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. 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. 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. 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. 6 Models WF2150, WF2154, WG2160 and WG2164 Welding Guidelines General The WF2150 and WF2154 can utilize the Flux Cored Arc Welding (FCAW) process. The WG2160 and WG2164 can utilize the Flux Cored Arc Welding (FCAW) process or the Gas Metal Arc Welding (GMAW) process. The weld must be protected (shielded) from contaminants in the air while it is molten. The FCAW process uses a tubular wire with a flux material inside. The flux creates a shielding gas when melted. The GMAW process uses inert gas to shield the weld while molten. When current is produced by a transformer (welding machine) and flows through the circuit to the weld wire, an arc is formed between the end of the weld wire and the work piece. This arc melts the wire and the work piece. The melted metal of the weld wire flows into the molten crater and forms a bond with the work piece ...
