Resumen del manual
Install drive rolls and turn drive roll nut one click. During maintenance intervals, remove drive rolls, and clean grooves using a wire brush. Check groove of drive roll for pitting or increase in the depth of the groove indicating drive roll is worn out. Tools Needed: 3/8 in OM-193 472 Page 15 3-11. Installing And Threading Welding Wire Tools Needed: 1 Retaining Ring 2 Hub Tension Adjustment Nut If necessary, move hub on support for use of different size wire spool. Remove retaining ring, and install spool so hub pin fits spool hole. Reinstall retaining ring. Adjust tension nut so wire is taut when wire feed stops. 3 Pressure Assembly Adjustment Knob Lay gun cable out straight. A Open pressure assembly, hold wire tightly, and cut off end. Push wire through guides into gun. B Close and tighten pressure assembly. Press JOG button until wire comes out gun. C To adjust drive roll pressure, press gun trigger to feed wire against wood surface. Tighten knob so wire does not slip. Cut off wire. Close door.

Front Panel Controls 1 Optional Voltage/Wire Speed Meter 2 Optional Voltage/Wire Speed Switch Use to choose volts or wire feed speed display. 3 Optional Remote Voltage Control Use to set welding power source voltage at the wire feeder. Numbers are for reference only. 4 Wire Speed Control 5 Jog/Purge Switch Use Jog position to momentarily feed welding wire at speed set on Wire Speed control without energizing welding circuit or shielding gas valve. Use Purge position to momentarily energize gas valve to purge air from gun or adjust gas regulator. 6 Trigger Hold Switch Push up to weld without holding gun trigger throughout the weld cycle. To start weld cycle, press and release gun trigger within three seconds after an arc has been struck. To end weld, press and release gun trigger. Power switch is on rear panel (see Section 3-5) 192 503-C 2 3 4 5 1 6 OM-193 472 Page 17 4-2. Optional Side Panel Controls Ref. 802 357-A / Ref. 186 589 / 210 436-A 1 Preflow Control Control sets time gas flows before welding wire is energized. Time range is 0 to 5 seconds. 2 Postflow Control Control sets time gas flows after completion of burnback. Time range is 0 to 5 seconds. 3 Spot Time Control Factory set for 0.25 to 5 seconds of spot time. Rotating knob fully counterclockwise selects an untimed continuous weld. 4 Run-In Control Use control to set wire feed speed before arc initiation. Close side door. 3 1 2 4 SECTION 5 . MAINTENANCE & TROUBLESHOOTING 5-1. Routine Maintenance Disconnect power before maintaining. 3 Months Replace Unreadable Labels Clean And Tighten Weld Terminals Repair Or Replace Cracked Weld Cable 14-Pin Cord Gun Cable Gas Hose Replace Cracked Parts 6 Months Blow Out Or Vacuum Inside, During Heavy Service, Clean Monthly OR Clean Drive Rolls OM-193 472 Page 18 5-2. Overload Protection Turn Off wire feeder and welding power source. Stop engine on welding generator. 1 Circuit Breaker CB1 CB1 protects wire feeder from overload. Correct problem and manually reset breaker. 802 349-A 1 5-3. Troubleshooting Trouble Remedy Wire does not feed, unit completely inoperative. Turn Power switch On. Check 14.pin plug PLG2 connections. Check input power. Wire does not feed. Check circuit breaker CB1. (see Section 5-2) Check gun trigger connection at wire feeder. Check gun trigger leads and trigger switch. See gun Owner’s Manual. Run-In speed is set to minimum. Normal setting is 50 percent. Have Factory Authorized Service Agent check drive motor and control board PC1. Wire feeds erratically. Readjust hub tension and drive roll pressure (see Section 3-11). Use correct size drive roll (see Parts List). Clean or replace dirty or worn drive roll (see Section 3-10). Remove weld spatter around nozzle opening. Replace contact tip or liner. See gun Owner’s Manual. Have Factory Authorized Service Agent check drive motor and control board PC1. Wire feeds when Jog switch is pressed but not when gun trigger is pressed. Check gun trigger connection at wire feeder. Check gun trigger leads and trigger switch. See gun Owner’s Manual. Wire feeds as soon as power is applied. Check gun trigger. See gun Owner’s Manual. Wire does not feed until trigger is pressed but continues to feed after trigger is released. Check for short between gun trigger leads and weld cable. Repair or replace gun trigger leads. Gas valve rattles loudly and wire feeds slowly or erratically. Check for short between gun trigger leads and weld cable. Repair or replace gun trigger leads. Gas does not flow; wire feeds. Check gas valve and flowmeter. OM-193 472 Page 19 SECTION 6 .
