anyone familiar or have a service manual for the one in the pics ?
it appears to be lacking some hv to start, used it at the weekend, and i had to scratch start...
it went intermittent a while ago then fixed itself.
I don’t know that particular model but, it will most likely have a set of points inside for the HF. It sounds like a good clean and setup may sort your probloem.
had another look today
when i push the button, gas comes on, but the pre gas flow pot appears to do nothing... the pre gas led does not come on and i can scratch start immediately.. (the middle led comes on straight away)
dont think it used to do that before... and i assume that i shouldnt be able to start welding until the pregas timer has expired?
think i am going to have to get into the shielded box at the front..
guess if i took something that old to a repair place i would get laughed at ?
must be at least 30 years old
i am an electrician by trade, not a welder and am starting to feel out of my depth
Reckon I getting somewhere... just chopped out a suppression? Capacitor on the output to the torch... now have hf start..not gonna use it till I have something to replace with, just in case it kills something else
The welder has several similar caps all over.. might be worth replacing all
