question about gas mig welding hey guys i bought the lincoln weld pak 3200hd and have since bought a gas canister and am welding with .025 gas wire. My only problem is that the puddle from welding is drying much faster than the flux core wire was drying and i cant keep a constant puddle going....
another thing that i am noticing is that the tip and the wire are starting to get welded together and these are all problems that i never had without gas...am i doing something wrong? too much gas? not enough gas?
What is a suggested pressure to use coming out of the bottle...
Thanks
Louie

A few suggestions:
For the gas, hopefully your regulator has two gauges. One for tank pressure and one for output CFM. Adjust the CFM to between 20 - 25 CFM. Make sure to weld where there is little or no wind.
Couple of thoughts on wire sticking to the tip: 1. The wire may not be clean enough or lubed. Ask your local welding store for some lube pads (look like felt with an attachment clip) and lube oil. These pads both clean the wire and add a little lube - this is a good idea even if it does not solve your immediate problem. 2. Your wire speed may need to be a little higher 3. Adjust the "stick-out", should be about 3/8" out of the nozzle (is it burning back?). 4. Check the pressure on the drive rollers (too little and the wire won't feed at a constant rate, too much and the wire can be flattened).
Hope this helps.

hmm...thanks guys these are all things thath i need to try.
there are two guages i am not sure what i had the CFMs set at as i was trying to adjust it to work better for me. Increasing the wire speed did help my problem to an extent...
But i will definately try all of the suggestions.
Thanks

well a combination of faster wire feed and an increase in power(heat) led a pretty good looking weld.
Thanks guys!
i cant wait til i have to weld something now.

one gauge is what your bottle pressure is - basically how much gas is in your tank.
the other gauge is your CFM out put - basically how much gas your welding tip is putting out.
