Installing Wire Spool And Adjusting Hub Tension When a slight force is needed to turn spool, tension is set. 1/2 in Tools Needed: 803 012 / 803 013 -B / Ref. 802 971-C 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. OM-925 Page 18 5-10. 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. 4 in (102 mm) Remove gun nozzle and contact tip. Open pressure assembly. Make sure feed roll is set to correct groove to match wire size (see Section 7-4). Push wire thru guides into gun; continue to hold wire. Hold wire tightly to keep it from unraveling. 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. 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 or if set in the “PURGE” position. 6 in (150 mm) Tighten 1 2 3 4 Use pressure indicator scale to set a desired drive roll pressure. 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. 6 1 3 4 2 5 SECTION 6 . OPERATION 6-1. Controls 12 P URG E 1 43 2 DO NOT SWITCH WHILE WELDING V NE PAS CHANGER DE PROCEDE 1 Wire Speed Control Use control to select a wire feed speed. As Voltage switch setting increases, wire speed range also increases (see weld setting label in welding power source or Sections 6-2 or 6-3, as applicable). 2 Power Switch 4 3 3 Voltage Switch The higher the selected number, the thicker the material that can be welded (see weld setting label in welding power source or Sections 6-2 and 6-3, as applicable). Do not switch under load. . Switch must “click” into detent position 1, 2, 3, 4, or purge for proper contact. Ref. 217 617-A 4 Voltage Switch - “Purge” Position In purge position, fan runs but there is no weld output or wire feed. Use “PURGE” setting when adjusting gas flow at the regulator.

Routine Maintenance Disconnect power before maintaining. 3 Months Replace unreadable labels. Repair or replace cracked weld cable. Clean and tighten weld terminals. 6 Months Blow out or vacuum inside. During heavy service, clean monthly. Or 7-2. Overload Protection 802 441 1 Circuit Breaker CB1 CB1 protects unit from overload. If CB1 opens, unit shuts down. Reset breaker. 1 7-3. Drive Motor Protection Drive motor protection circuit protects drive motor from overload. If drive motor becomes inoperative, release gun trigger and wait until protection circuit resets allowing drive motor to feed wire again. OM-925 Page 25 7-4. Changing Drive Roll Or Wire Inlet Guide 1 Inlet Wire Guide Securing Screw 2 Inlet Wire Guide Loosen screw. Slide tip as close to drive rolls as possible without touching. Tighten screw. 3 Drive Roll The drive roll consists of two different sized grooves. The stamped markings on the end surface of the drive roll refers to the groove on the opposite side of the drive roll. The groove closest to the motor shaft is the proper groove to thread (see Section 5-10). 4 Retaining Pin To secure drive roll, locate open slot and push drive r...
