see NEC Article 511 or CEC Section 20. Disconnect and lockout/tagout input power before connecting input conductors from unit. Always connect green or green/yellow conductor to supply grounding terminal first, and never to a line terminal. 1 Rating Label Supply correct input power. 2 Plug 3 Receptacle Connect plug to receptacle. 4 Black And White Input Conductor (L1 And L2) 5 Green Or Green/Yellow Grounding Conductor 6 Input Power Cord. 7 Disconnect Device (switch shown in the OFF position) 8 Disconnect Device Grounding Terminal 9 Disconnect Device Line Terminals Connect green or green/yellow grounding conductor to disconnect device grounding terminal first. Connect input conductors L1 and L2 to disconnect device line terminals. 10 Over-Current Protection Select type and size of over-current protection using Section 3-12 (fused disconnect switch shown). Close and secure door on disconnect device. Remove lockout/tagout device, and place switch in the L2 L1 On position. 230 VAC, 1 3 7 6 L1 L2 1 =GND/PE Earth Ground 5 4 8 9 10 OM-192 440 Page 18 3-14. Threading Welding Wire Ref. 802 285-D 1 Wire Spool 2 Welding Wire 3 Inlet Wire Guide 4 Pressure Adjustment Knob 5 Drive Roll 6 Outlet Wire Guide 7 Gun Conduit Cable Lay gun cable out straight. Tools Needed: 6 in (150 mm) Pull and hold wire; cut off end. 4 in (102 mm) Tighten Remove gun nozzle and contact tip. Turn On. WOOD Press gun trigger until wire comes out of gun. Reinstall contact tip and nozzle Feed wire to check drive roll pressure. Tighten knob enough to prevent slipping. Cut off wire. Close door. Open pressure assembly. Push wire thru guides into gun; continue to hold wire. Close and tighten pressure assembly, and let go of wire. Hold wire tightly to keep it from unraveling. 1 2 3 4 Use pressure indicator scale to set a desired drive roll pressure.

Installing Optional Spool Gun Switch In Welding Power Source 802 936-A Tools Needed: 1/4 in 9/16 in Turn Off unit, and disconnect input power. 1 Welding Power Source Center Baffle 2 Switch Location 3 Switch Mounting Plate Remove 2 screws securing switch mounting plate to center baffle. Pull switch mounting plate to pull wiring harness through center baffle hole. 4 Plastic Plug Remove and discard plastic plug from center hole in switch mounting plate panel. 5 Nylon Cable Tie Cut and discard nylon cable tie. 6 Jumper Plug 7 Wiring Harness Switch Plug Remove jumper plug from wiring harness switch plug. Retain jumper plug by placing looped lead over unit wiring harness. 8 Switch Plug Connect switch plug to wiring harness switch plug. 9 Jam Nut Remove top jam nut from switch (switch is equipped with two nuts, a jam nut and a backing nut). Insert switch shaft through switch mounting plate. Switch should be positioned so lead with resistor is facing down. Secure switch to plate with jam nut. Tighten jam nut enough to keep switch from rotating. Push wiring harness back through hole, and reinstall switch mounting plate to center baffle. Operation: Place switch in On position for spool gun operation. Place switch in Off position for wire feeder/MIG (GMAW) gun operation. When spool gun switch is in On position, spool gun wire feed speed is controlled by welding power source Wire Speed control. 3 9 4 3 6 5 8 7 2 1 3-16. Connecting Spool Gun To Welding Power Source Ref. 802 582-A Tools Needed: Turn Off unit. Disconnect and remove MIG (GMAW) welding gun, if applicable. 1 Front Panel Opening 2 Spool Gun Weld Cable Route weld cable through front panel opening. 3 Positive (+) Output Terminal Connect spool gun weld cable to positive (+) output terminal. 4 Work Clamp Lead Work clamp lead should be connected to negative (.) output terminal. 5 Existing Gas Hose 6 Spool Gun Gas Hose 7 Gas Diverter Valve To install diverter valve, cut existing gas hose above barbed fitting at wire drive housing. Install supplied hose clamp onto end of hose at wire drive housing, and insert either of the two output barbed ends of diverter valve into hose. Secure with hose clamp. Install another supplied hose clamp onto end of hose from gas supply, and insert input barbed end of diverter valve into hose. Secure with hose clamp. Slide hose clamp down gas hose from gun, and cut barbed fitting off hose. Route gas hose through front panel opening, and insert remaining output barbed end of diverter valve into hose. Secure with hose clamp. 8 Trigger Control Plug Insert plug into receptacle, and tighten threaded collar. Close welding power source door. 3/4 in 7 6 5 23 4 8 1 5 6 OM-192 440 Page 20 SECTION 4 .
