HELP Can't find any info on my mig welder can you help??????????

[glnutt]

HI I'm new here and I'm need help.
I have a 120v S.A.M. automatic mig welder . It was made in Canada by Controlled Systems a company I can find nothing at all on. This welder is Probably 12 -15 years old ,but with very little use.
I have found a few old listing for them on selling site call kiliji or something close to that. But nothing else.
I believe the circuit board has a bug or something in it . the wire feed isn't working.
I've checked out the switch it's ok. also put external power to the motor , when I
do that the motor works find. gas solenode works but shuts itself off after a few seconds.
Any ways I'm looking for someone or some place that works on these. or maybe someone that has a wire schmatic. anything that might help diagnoise the problem.
If you can help PLEASE let me know

I had a search about and couldn't find much apart from some old classified ads. Post a photo and someone might be able to identify it.

The problem does sound like the circuit board. If it's been out of use my guess would be the relay that switches power to the torch. They are often inside a transparent cover which you can pull off to clean the contacts with sandpaper.

It was welding fine then started acting up a little when we went to start another weld it just did do much of any thing . The gas continued to work.
I have the circuit board off and there is no relay . This machine only has one adjusting knob for heat and wire speed it say on the front factory preset . I don't have any way to but a picture up on this computer I'll see if I can from someone else's this weekend.
thanks for your time and help.
Thanks to both replies hope this answers your replies
