Unknown MIG wire feed units?

[wheresmejumper]

Yes you were right . ordinary mig feeders need a constant voltage supply, like a mig welders power source.they wont work properly with a tig/arc supply as they are constant current.
but there are mig wire feeders out there that have fancy electronics that let them work off of any power source, constant current or constant volatge.they are normally more expensive, but come up for sale every now and then.
Miller do one, theres the thermal arc hefty, the lincoln ln25, newarc do one

the lincoln and powcons have a switch to change from constant current to constant voltage

And so it is possible that mine may also be fancy enough to manage with anything I can stick through it - but I have no way of knowing, and Google hasn't revealed any specs?

Which 150 do you have? Older one or the V2
ps you already have a power source it's call a Sealey
Any chance of a pic of the inside (other side from the wire feed rollers)

It could be but it would normally say cv/cc somewhere on it

I'm not with the welder at the moment, but it looks like one of these:



Which appears the same as the one in your picture. I've never been inside it though, I've normally run out of patience with it by then and just used the stick - even on exhausts!

That brings back some horrible memorys

You loved yours too then

I lent it out to someone a while ago to weld up an old disco, they went through a 5kg roll of wire and loved it, but I simply can't get on with it. The standard I can achieve with it is nothing compared to what I used to be able to do when I was using what I call proper machines. Time has passed since then, but I did get quite capable and can't have lost it that much!

I was referring to Arc welding thin metal and exhaust.... yuck
I think the difference between a "proper welder" and a DIY type is a lot to do with the feed mechanism. As many diy type use a feed from the welding voltage, not the best ideal!!
