Hi all I have a problem with my ESAB 195 power compact, bit of a rare model mine is model number 0001 had it since it was given to me many years ago by the importer. It has an earth circut drop out problem with the contactor switch as soon as it gets hot, I have replaced the control module and checked all other components and am completely stumped. It has been recomended that I replace the contactor with a Triac but have not been able to find one to suit as according to most that make them the 195 dosnt exsist. The unit is a 230/240v 16amp input and the contactor is a 75Amp 3Phase unit (only 4 poles are used). Any help would be appreciated before I rip out whats left of my hair. Thanks
