Installing Gas Supply Obtain gas cylinder and chain to running gear, wall, or other stationary support so cylinder cannot fall and break off valve. 1 Cap 2 Cylinder Valve Remove cap, stand to side of valve, and open valve slightly. Gas flow blows dust and dirt from valve. Close valve. 3 Cylinder 4 Regulator/Flowmeter Install so face is vertical. 5 Regulator/Flowmeter Gas Hose Connection 6 Welding Power Source Gas Hose Connection Connect supplied gas hose between regulator/flowmeter gas hose connection, and fitting on rear of welding power source. 7 Flow Adjust Flow rate should be set when gas is flowing through welding power source and welding gun. Open feedhead pressure assembly so that wire will not feed. Press gun trigger to start gas flow. Typical flow rate is 20 cfh (cubic feet per hour). Check wire manufacturer’s recommended flow rate. After flow is set, close feedhead pressure assembly. Tools Needed: Ref. 804 654-A / 802 441 / Ref. 804 623-A 5/8, 1-1/8 in 6 Argon Gas Or Mixed Gas DO NOT use Argon/Mixed gas regulator/flowmeter with CO2 shielding gas. See Parts List for optional CO2 gas regulator/flowmeter. Feedhead Pressure Assembly Open Feedhead Pressure Assembly Closed 1 2 3 4 5 7 A complete Parts List is available at OM-925 Page 15 5-6. Selecting A Location And Connecting Input Power 1 Rating Label 2 Grounded Receptacle A 115 volt, 20 ampere individual branch circuit protected by time-delay fuses or circuit breaker is required. 3 Plug From Unit Select extension cord of 14 AWG for up to 50 ft (15 m) or 12 AWG for 50 up to 200 ft (61 m). Special installation may be required where gasoline or volatile liquids are present . see NEC Article 511 or CEC Section 20. 3 803 712-C Do not move or operate unit where it could tip. 2 1 18 in (460 mm) 18 in (460 mm) A complete Parts List is available at OM-925 Page 16 5-7. Installing Wire Spool And Adjusting Hub Tension When a slight force is needed to turn spool, tension is set. 1/2 in Tools Needed: Installing 8 in (203 mm) Wire Spool Installing 4 in (102 mm) Wire Spool When a slight force is needed to turn spool, tension is set. Retaining ring used with 8 in (203 mm) spool only. Adapter used with 8 in (203 mm) spool only. 803 012 / 803 013 -B / Ref. 802 971-C Align locking hole in spool with locking pin on spool hub. A complete Parts List is available at OM-925 Page 17 5-8. Installing Contact Tip And Nozzle Tools Needed: Ref. 802 399-A Turn off welding power source. 1 Nozzle Remove nozzle. 2 Contact Tip 3 Tip Adapter Thread welding wire through gun (see Section 5-9). Slide contact tip over wire and tighten tip into tip adapter. Install nozzle. Flux Nozzle (Optional) MIG Nozzle (Standard) Use with flux cored wire only. Narrow design allows access in tight spaces and provides better visibility of puddle during welding. Use with solid or flux cored wire. Push nozzle over contact tip and adapter until it is seated onto adapter. Contact tip will be exposed approximately 7/16 in (11.3 mm) when installed properly. Push nozzle over contact tip and adapter until it is seated onto adapter. End of contact tip will be flush with end of nozzle when installed properly. 1 2 3 A complete Parts List is available at OM-925 Page 18 5-9. Threading Welding Wire 1 Wire Spool 2 Welding Wire 3 Inlet Wire Guide 4 Pressure Adjustment Knob 5 Drive Roll 6 Gun Conduit Cable Lay gun cable out straight. Tools Needed: Pull and hold wire; cut off end. Open pressure assembly. Make sure feed roll is set to correct groove to match wire size (see Section 7-4). Hold wire tightly to keep it from unraveling. 6 in (150 mm) 6 1 3 4 2 5 1 2 4 in (102 mm) Straighten approximately 3 or 4 inches (76 or 102 mm) of wire before inserting wire into guides. Push wire thru guides into gun; continue to hold wire. 3 A complete Parts List is available at OM-925 Page 19 Remove gun nozzle and contact tip. Ref. 803 714-A WOOD Feed wire to check drive roll pressure. Tighten knob enough to prevent slipping. Cut off wire. Close door. Press gun trigger until wire comes out of gun. (Keep gun cable as straight as possible.) Turn power on. Be sure that Voltage range switch is set to range 1, 2, 3, or 4 to feed wire. Rotate knob until it “clicks” into detent. Wire will not feed if range switch is set between ranges. Tighten 1 2 3 4 Use pressure indicator scale to set a desired drive roll pressure. (Start with a setting of 2 or 3 on the scale.) Pressure Indicator Scale Tighten 1 2 3 4 Be sure that wire is positioned in proper feed roll groove. Close and tighten pressure assembly, and let go of wire. Be sure that tip matches wire diameter. Reinstall contact tip and nozzle. 4 5 6 7 8 9 . A complete Parts List is available at SECTION 6 . OPERATION 6-1. Controls 1 Wire Speed Control Use control to select a wire feed speed. As Voltage switch setting increases, wire speed range also increases ...
