Thank you. Can I just put in some flux core wire the same size as the wire in there now and start practicing without shielding gas?

I just picked up a mig welder to learn on myself. My welder requires different polarity between solid wire/gas and flux core wire, not sure if yours is the same.

Yes you can use flux cored wire. It spatters a little more than solid wire and is more expensive, but works fine.

This is correct information! I’m sure you can use Flux with that machine but you will have to swap your polarity over or it will not work right.

Thank you. Do I just make the ground lead positive using these jumpers to change polarity?

Can't see where your cables go, but flux-cored welding requires DC electrode negative.

Buy the bottle, it is cheaper then renting and when you run out you just swap the bottle for a full one.

I pay $40 per year for my co2 bottle and swat when needed. Only paying for the co2 in the bottle.

Thank you. That would make sense. The ground clamp currently goes into the upper left and that little chart on the front would indicate a DC - if I changed their position.

I may start out practicing with this and add a shielding gas if I find I need it for an application. I don't really have any current use for the machine but I should at least know how to operate it if it is in the garage.

As I was scrolling through this thread this is what I was thinking. If you are unfamiliar with welding, flux core is the way to find out if your going to like it or not before buying tanks and parts.

In photo of - and + they could be just plugs so just pull and swap..to change polarity.My machine has wing nuts to remove to swap...as for flux core it can really shine in windy outdoor conditions...But gas shield in controlled conditions sure make clean splatter free welds.

as for fittings go to Welding supply with your parts and machine they can fix you up...and not TSC cause their gas prices are HIGH..2/or 3 times...Went to get swap a bottle of 02 a while back it was $58bucks I said no..went to weld supply it was $18
