Hey there, I have an old Airco 300 amp AC/DC Heliwelder V square wave that has been sitting in the garage for years. My father got it from his brother years back and it has been sitting ever since, I had some down time and decided to play around with it.
The welder seems to power on just fine, cooling fan starts right up. When I try stick welding with it, it will not strick an arc, it acts like the amperage is set way to low, I get a few small blue sparks but thats it. The same applies when I tried changing the polarity and tig welding with it. Using the foot contorl does not make a difference either.
I have checked the fuses, the relays on the board and the potentiometer for the amperage dials, they all seem fine.
Before I try and get ride of this thing, has anyone had a similar problem? Anyone got any ideas?
