I recently bought a Lincoln 135 Wire feed MIG welder.

Up until earlier today i had been using the flux cored wire to just get a feel for it and it had been working fine just with tons of slag and spatter.

Today i went out and bought a tank of C02/Argon blend. I connected all my gas lines properly and switched the polarity on the machine, but i just cant get an arc going. The molten wire just beads up and rolls off or just stays on the end of non liquefied wire. Can someone tell me what the deal is? Yes i switched to the proper MIG wire and everything. Ive tried adjusting the gas to 9 lp/m at 12 lp/m ive tried just about everything. It sounds like the gas is just blowing the arc out, no matter how low i set the reg.

any help would be greatly appreciated.

Ive posted this on a few forums now ( other welding forums) and no one can seem to give me an answer.

 

can't help you - i think you would be best contacting your local supplier or the welding machine company

 

What wire are you using? Thickness? Base metal thickness? Sounds like either your feed is too slow or your voltage isn't high enough.

If your voltage isn't high enough the wire will just push the gun back towards you once it hits the base metal.

If your feed is too slow it will arc for a second but then stop and since it balled up at the end it can't make a good circuit and won't arc again until you clip the end.

 

.025" L-56 MIG wire. At the moment im using a thick peice of stock about half an inch thick to just try and throw a bead on. Ive also tried it on some thinner material and had the same issue. I think i may need to crank my gas and purge all my lines again.

Ive set the voltage up pretty high and set the wire feed at 7 ( higest is 10 )

I dont know, ill give some more stuff a try tonight.
