Hi everyone, i have a question about changing my mig polarity to negative gun positive earth, how is that achieved on my machine??
really need to know exact model to be sure. but quick google shows that you swap over a lead which is inside the machine next to the wire spool. one connection is marked flux core.
if in doubt post pics.

I'm assuming that if you change earth lead from negative to positive it gives you what is needed for flux core wire?

Is it similar to this one?

Is there a polarity swap terminal set inside the wire bay like this?

Different how?
I think you need to be a bit more forthcoming with information. Do you have a manual? Does it say that both MAG/MIG and FCAW-S are supported? Is there anything similar to what I posted on yours? What about a picture?
Jack
can you take a pic of the wire spool area? any buttons, switches, leads etc. i would not be surprised if its not changeable despite the claims that its gasless.
looks like your one is a slightly older model. its also sold under various other names eg rossi.
i havn't found a good manual for it, which is not uncommon with these sorts of machines.

Learner - What you are trying to do is to swap from DCEP to DCEN. Most older MIG machines have a stud inside the cabinet where you can swap the polarity. It looks something like this (photo attached). You should find it near the spool area, perhaps around where the gun cable penetrates the roller assembly.
If you can swap it, make sure to swap it back to run standard hardwire MIG from FluxCore wire.

Hi everybody, the only connection inside spool area is a negative terminal no other cable in there, the positive cable runs inside of wire feed.
sounds like its a gas mig only.
btw does it even come with fluxcore rollers ? https://www.boc.com.au/shop/en/au/boc-1 ... 03-05-00-p
trade it in on something better. make sure you get one with fluxcore rollers.
