Help my Transtig 150 is not working
Hi I am having a horror run with Transtig welders at the moment. I recently purchased a EMF 250 Transtig which is in great condition but its too big for me and won't fit in my workshop. Apparently this works just fine and hasn't seen too much work as it was a Tafe machine. So then I purchased a later model Transtig 150 single phase and the right size for what I am looking for BUT it does not want to work. When it is switched to Arc mode I can't strike an arc to weld MMA. When I switch it to TIG (I have no torch just yet as it came with the wrong one) it will strike an arc using the MMA leads and rod. It will strike an arc without pressing the pedal, when I switch it to Tig mode it makes a funny fluttering noise which I assume is the HF circuit.
Can anybody point me in the right direction to get this fixed? I have opened it up and inspected the PCB and hardware and nothing seems to be burnt or pitted all connections seem to look good. I think there has been a couple of iterations from Cigweld since my unit was built but it was working OK from what I was told.
Can anyone help me to get this unit fixed in Melbourne? I don't want to have to scrap it or get rid of it as it is pretty clean and is a good piece of Aussie engineering. One thing I have noticed is that one of the cables used for switching polarity on the front of the unit is scorched at the plug end, I can't imagine that this would be an issued however it is worth noting as it seems to be the only thing that remotely looks burnt.
any help much appreciated.
cheers
