I'm confused:confused::confused: I weld steel with CO2 which is an inert gas so am I mig (metal inert gas) welding or mag (metal active gas) welding?
 
is it a pure co2? or does it have a mixture?

im sure pure co2 is designed for use on short circuiting work(thin steel to stop distortion)
 
thought the idea of any welding gas, was to remove the oygen from the weld pool & arc in order to prevent oxidisation & corruption of the weld.

totaly correct:D

but some exotic materails wont weld very well using certain gases

where as mild steel will shield with lots of different gases(but will look ****ey):p

think the clue is in the "inert gas" part... :doh:

well if you can find me one person on the planet that can mig weld mild stell id love to meet him,


MIG/MAG welding is used on all thicknesses of steels, aluminium, nickel, stainless steels etc. The MAG process is suitable both for steel and unalloyed, low-alloy and high-alloy based materials. The MIG process, on the other hand, is used for welding aluminium and copper materials.

there you go everone calls there welder a mig welder when infact its more than likly a mag ;)

but, but, but, apparently you can only mig weld aluminuminuminum and copper:confused:

Bollixs. mig is inert gas in this case usually argon mag is an active gas usually CO2

But its only the nerds who really give a toss - its semantics really. ;)

Seriously - why bother confusing matters with MIG/MAG talk? These days MIG/MAG are interchangable terms. If Miller & Lincoln et al all refer to their product range as MIG then why even bother on a forum like this?
 
I've got an arc welder and I've stuck with it. It was a right pain to get used to, but now I've got experience with it and the really helpful auto' mask, I think it's brill. No fecking about with the wire, no tips to worry about.
MIG'S are for light weights.....there, Ive said it! :)
 
The problem I have with me wire fed welder :D , is when I need it, the wire's gone rusty and gas is empty (pub gas crap valves). All the arc needs is some dry rods and it's ready.
Did get caught with some in the oven last week ,missus got that foam stuff and made me clean it, said it would make the cakes taste funny, told her it would make a change from the burnt taste :D .
 
there ant nuffing wrong with useing Co2 i use it all the time its down to operators experience , plus its a hell of a lot cheaper then argon gas
