First a bit of background.
2019 I bought a Lidl welding machine.
This is a Parkside PFDS 120 A2
For under £100 the machine is well worth the money. I made so far my trailer's frame.
My Floodlight stand
and a few other minor works.
No complains about it except the wire needs to be a flux core, for those who don't know about mig welding there are 2 types of wire for welding.
Now, I know that some, more expensive mig welders can use both FC wire and gas shielded wire and this becomes possible by inverting the polarity (IP).
My question is, how can I invert the polarity on this welder?
I've open it but opposite to the mig welders doesn't have the connectors for IP.
The cables connect directly from the secondary coil into the cables. with some small cables feeding into the circuit board, I believe these will be some load protection.
I would imagine that inserting 2 connectors just before the cables leave the box will allow the IP and the machine becoming normal and flux core wire.
By the way, yes I know the normal wire used without the gas will make a hell of a spatter, even more than flux core.
The reason why I want to invert the polarity is because by mistake I bought a 5kg reel that instead being flux core is normal wire.
Although the normal wire is corrosion resistant because of the copper coating.
Thanks in advance
