hello everyone
just wondering if anybody knows anything about a tig welder that someone has asked me to take a look at its an union carbide tigger hd 150 (old transformer based tig) it works in as much that the hf works but no welding current.
its either thyristor or triac controlled (no part number on said component)
on the primary side of the transformer and when bypassed it will work at full welding current so that proves the rest of the machine works.
i cannot find much information about this welder but i expect its a rebranded version of another make , i am trying to find a circuit diagram to be able to repair it can anyone help?
