welding question

[RockHillCJ-6]

can you mig weld with just co2? if so, has anyone done it? pros/cons? if not: i have a 50 or 75lbs(cant remember) bottle of it, is it possible to trade that for argon/co2 mix at one of the welding/gas shops in town?
thanks

yeah you can weld with CO2, it is going to burn a little hotter and you will get some more spatter but it works well. Also CO2 is alot cheaper about half of the price and it will last for about 5 times longer than argon/co2 mix.

Another plus is that you can get a high pressure regulator for the bottle and use it as onboard air. It works great for airing up tires

so will it give a nicer/better weld then running gasless like i am now?

[CheapJeep]

Yes.

Are you welding with flux core wire?

[agjohn02]

i had an old man neighbor in my undergrad days that wouldnt use either b/c gas was too much trouble and fluxcore was too expensive. luckily, he didnt weld much. i never could convince him you needed one or the other, he thought they were optional, just to make the weld prettier.

[AggieTJ2007]

I should show him how to weld with bare electrodes even cheaper than mig wire

you just breath CO2 onto it?

[RockHillCJ-6]

yes i am using fluxcore, i thought thats all you could use gasless?

it is, mike is dumb, or maybe he pours out a pile of granular flux and welds blind. either way...

[RockHillCJ-6]

oh, ok. well fluxcore has been ok for me so far, i just want to have a little better and nicer weld

If you have someplace to weld indoors, switch it over to gas, you'll like it better. If you're outside or any place windy, the shield gas will get blown away and it will look like cacapoopie (technical term)

Go back to working on your jeep

I disagree, all you need is a good wind block (i.e. fat ass or tarp :D )

[RockHillCJ-6]

well, i am welding indoors so i guess ill be switching to gas
