CHIEF 2000 HERTZ DC INVERTER WELDER R USERS MANUAL Welding On One Side (Pistol) 1. Fit welding electrode to pistol. (See unit components page 2.) 2. Clamp ground shoe to bottom piece of steel prior to welding top piece of steel to bottom piece of steel. NOTE: When applying a pistol weld to top piece of steel, the ground shoe must be clamped to the bottom piece of steel to allow a flow of current through the two parts. 3. Select program and thickness of sheets to be welded.
CHIEF 2000 HERTZ DC INVERTER WELDER R USERS MANUAL Seam Welding IMPORTANT: Seam spot welding does not have the strength of a MIG weld and should never be used for structural welding. Due to its low emission of heat; however, seam spot welding is very useful for patching holes on panels. 1. Fit proper electrode in the pistol. (See unit components - page 2.) 2. Clamp ground shoe to bottom piece of steel prior to welding top piece of steel to bottom piece of steel.
CHIEF 2000 HERTZ DC INVERTER WELDER R USERS MANUAL Welding Of Studs, Nuts And Moulding Rivets 1. Fit appropriate electrode in the pistol. (See unit components - page 2.) 2. Clamp ground shoe to steel sheet (panel, etc.) prior to welding a stud, nut or moulding rivet to the steel sheet. NOTE: When applying a pistol weld, the ground shoe must be clamped to the steel sheet to allow a flow of current through the component (stud, nut or moulding rivet) and the steel sheet. 3.
CHIEF 2000 HERTZ DC INVERTER WELDER R USERS MANUAL Dent Pulling 1. Fit slide hammer in pistol and fit wedge plate in slide hammer. (See unit components - page 2.) 2. Clamp ground shoe to steel sheet (panel, etc.) prior to welding wedge plate to dented portion of steel sheet. NOTE: When welding wedge plate to steel sheet and when pulling the dent, the ground shoe must be clamped to the steel sheet to allow a flow of current through the wedge plate and the steel sheet. 3.
CHIEF 2000 HERTZ DC INVERTER WELDER R USERS MANUAL Panel Pulling 1. Fit washer weld electrode in pistol. (See unit components - page 2.) 2. Clamp ground shoe to steel sheet (panel, etc.) prior to welding of washer(s) to the steel sheet. NOTE: When welding washer(s) to the steel sheet, the ground shoe must be clamped to the steel sheet to allow a flow of current through the washer(s) and the steel sheet. 3. Select program and thickness of sheet to be welded.
R CHIEF 2000 HERTZ DC INVERTER WELDER USERS MANUAL Smoothing Out Bumps 1. Fit proper electrode in the pistol. (See unit components - page 2.) 2. Clamp ground shoe to steel sheet (panel, etc.) prior to smoothing out bumps in steel sheet. NOTE: When smoothing out bumps in steel sheet, the ground shoe must be clamped to the steel sheet to allow a flow of current through the electrode and the steel sheet. 3. Select program and thickness of steel sheet used.

CHIEF 2000 HERTZ DC INVERTER WELDER R USERS MANUAL Diagnosis And Remedies Fault Possible Cause Remedies Welding control indicators do not light. Power supply fault. Check condition of main power line (unit connection, fuses, main circuit-breaker, etc.). If no power supply problems, call an authorized Chief representative. Machine’s circuit breaker trips. Weak power supply.
CHIEF 2000 HERTZ DC INVERTER WELDER R USERS MANUAL Diagnosis And Remedies..........continued Fault Possible Cause Remedies Dirty sheets (paint, primer, filler, excessive rust, etc.) Clean and remove excess paint, filler or rust. Too low electrode force. Increase welding effort. Worn electrodes. Clean, dress or replace electrodes. Poor quality welding primer. Use only high quality zinc welding primer “Saitek Z-Coat”. DO NOT use a copper or aluminum-based primer. Wrong settings.
CHIEF 2000 HERTZ DC INVERTER WELDER R USERS MANUAL Diagnosis And Remedies..........continued Fault Single sided weld has a nice appearance but is not consistent. Excessive sparks when welding with pincer gun. Possible Cause Remedies Incorrect settings. Reduce welding time and increase welding power. Poor location of ground shoe. Make sure ground shoe is close to spot of weld and that it is on bottom sheet and not on sheet where weld is to be applied.
