125AMP Flux Welder Mig Gasless, need to know what spool will work?
I have a speedway series Gasless MIG welder and is didnt come with wire, so I dont know much about the thickness of the wire.
I need some wire, if someone can point out some Alumium wire spool and Mild steel spool that will be compatable with my unit id appreciate it.
Thanks
I own a MIG welder, but mine is big, uses sheilding gas, and takes #44 spools.
Here are some facts to keep in mind and possibly research:
- If your welder is not going to be using a sheilding gas, you MUST use FLUX CORE wire when welding steel. It has a flux inside the hollow wire, which will protect the weld from Oxygen, like the gas would. So, be sure you're buying a spool of flux core wire, and not solid wire, if you do not use gas.
- A 125 amp MIG welder only has the power to melt wire up to a certain thickness. You might have luck going to the Lincoln and Miller websites, and looking up some owner's manuals for their 125 amp machines. There you might find what wire diameter range you can use. Chances are that it will be thinner than .035
- I don't know much about the little spools that fit those machines, but they all seem to be about the same size at the welding shop. They are small, somewhere between 4 to 6 inches in diameter. Perhaps it is a standard size, and you won't have any trouble finding one at all? Even Lowe's sells them, and those are all the same size, even though they come in several different alloys.
- I don't think they make a Flux Core aluminum wire. It barely wants to feed when it's solid wire...so a hollow version would probably jam like crazy. If the wire is solid, you will not be able to MIG weld aluminum without a shielding gas.
- you need to match the MIG gun's tip to the wire thickness you choose, and there may also be a "tip" of sorts inside the machine where the wire feeds into the liner, that needs to match the thickness of wire you have chosen. You may get lucky...if the welder has been used or set up before...the tips on it might specify a size on them, and you could choose a wire that way.
There's lots of info in those owners manuals...so don't forget to check out the websites.
Good Luck.
