HI FROM NEW ZEALAND.I HAVE A LISTER-PETTER 16 KVA DIESEL 3 PHASE GENSET WITH SINGLE PHASE SOCKET @ 240 VAC. WITH A ITALIAN ELECTRONIC DIAGNOSTICS CONTROL PANEL WITH BREAKERS ETC.WHEN RUNNING A ESAB CADDY PROFESSIONAL 140 INVERTER WELDER @130 AMPS USING 4 MM HARDFACING RODS, ON FIRST STRIKE THE GENSET CUTS OUT AND DIE.WHEN USING A COPPER WOUND TRANFORMER WELDER THE THING RUNS WELL BUT WILL NOT STOP WHEN I HIT THE KEY TO TURN OFF OR EMERGENCY STOP BUTTON.NOTE; THIS IS A STANDBY GENSET IN THAT I JUST PLUGGED IN A WELDER, THE GENSET IS NOT A DEDICATED WELDING GENERATOR.I USED OTHER DIESEL GENSETS PRIOR WITHOUT ANY PROBS.WILL ANY1 HAVE ANY CLUES? REGARDING THIS.THANKS IN ADVANCE.CHEERS CARL GIN
Does the Esab welder have high frequency? If so the high freq. is feeding back into the generator and frying the electronics. You may need to have the generators repaired. The only way to prevent damage is to turn the high freq. off, or drive an earth ground as close to the welder as possible and you have to run a wire to your grounding clamp to this ground and the machine ground needs to go to this also. You have to get the high freq. out of the circuit as quick as possible. (I have a Hobart Champion Fabshop that is notorious for this.)
