View original topic: offroaders are welders, maybe you can help

i have a lincoln weld-pak 100. a wire feed welder. i recently purchased the mig conversion kit along with some 75 argon/25 co2 gas. the welds are much cleaner, but it makes a very pronounced popping sound. as i weld, it appears some of the wire is melting into a ball onto the end of the wire coming out of the gun. as the ball drops, it makes the popping sound. can anyone help me find a solution to eliminating that sound, because im pretty sure its not right.

Hold the tip 3/8" to 1/2" from the material.
Also try turning up the wire speed a hair.

Also, what fo you have the regulator set at?

HamburgerBrad Tue Jan 27, 2004 9:58 pm

i have tried all kinds of combinations of wire speed, amperage, and gas flow. the regulator is set at 15 currently

Turn it up to 20.

What wire are you using?

spool says .030" superarc L-56

Try some .023. Smaller wire works better with the smaller welders on light gauge.
And L56 is about one of the best so stick with it.

the mig kit came with a small spool of .025? i'll give that a try in the near future. home depot didnt have any of the large spools of .025, so we got the .030

Don't forget to change the tip.
I would use a .023/.025 tip. The .030 would be a little big. The liner will be ok.

It is normal for solid wire to make that loud sound, compared to Innershield. You will have to experiment with heat settings and wirespeed to make proper welds.

thanks alot, both of you. my dad went to a welding supply store and they said to turn up the wire feed. that turned out to be it. we messed with the other settings and finally got it to a pretty decent setting
