Best welding wire?

[J-mark]

Hello fellas, I just bough my used welder is a miller 212 (non auto set) one owner with same tool of wire (rust it wire) the guys say don't have power 220 since he move to apartment complex, the machine work and weld but the wire had same rust spots so I'm going to buy new wire and I thing is good idea replace the liner at the same time! Or maybe replace another parts?
What u guy think any suggestions .
Thanks.

Best welding wire?

Don't run rusted wire through it.
If he didn't use it in awile chances are liner is ok. I'd get new wire. 1st pull out liner, blow out hose & liner, reinstall liner, put new wire in & try. Probably work fine but if not u can always replace liner. Ur not out anything except 15' wire.

I've seen guys use one of those spring style paper clips with some scotch bright placed on the wire before the rollers to take surface rust off might give you a bit before replacing spool and liner.

Don't use scotchbrite as they clog liners. There are little maroon pads that look like scotchbrite that are made for this. Unroll enough wire to get rid of the rust. It's usually o/k several layers in.

Agree; but ck with LWS on maroon pads for wire u buy. Most solid wire it's ok to use but some wire (dual shield,dual metal) hv a coating u can't see but is there for reason and they don't recommend using wipers.

Well...there are a lot of "best welding wire' type of wires around. Usually the "best" welding wire is the one that best matches whatever you are going to be welding on mostly and also it depends upon what kind of gas you have in the tank or what kind of gas you want or need to use, but most MIG machines for general all-around use have a tank of 75/25 (argon/CO2) with them for hard wire and the most common hard wire is some brand of ER70-S6 or very similar. Some guys prefer some kind of cored wire so covering gas is not needed and it is somewhat easier to use if it starts to get windy where you are welding.

Personally, I would use whatever is on it for now...gas, wire, liner and drive rolls but would, as suggested above, peel off a few layers of wire while looking for it to start getting shiny and for there to be no more rust (oh....and cut the wire and peel it off the roll...don't drag it through the liner as you will also drag the rust into it. Once you get down to shiny wire, re-thread the wire through the liner and the contact tip. I would also clean everything I could to ensure that it will all work as well as it can.). Oh, yeah...you might want to change the contact tip....they are CHEAP and if the one on there is bad for whatever reason (worn, contaminated, etc), you will have a much better chance of everything working best with a new contact tip! If you do this, it all might work just dandy and you won't be out any bucks for new wire, liners or drive rolls (if you happen to decide to go with a different sized wire than what came on it).

Good luck and have fun!!
