welding gas
Turbo Mini Forums

Just a quick question, whats the best gas to use with a mig welder? CO2, Argon or co2/argon mix?

getting me a mig tomorrow and a couple of the small bottles to last me over xmas.

if your getting the small bottles get the ones from machine mart with twice as much gass in them. for some reason they last ~6 times longer and are only a few quid dearer. when i was doin alot of welding i weas goin thro 3 of the regular bottles a day, but the machine mart ones were lasting 1 bottle for 2 days !!

turbo 16v k-series 11.9@118.9 :)

argon or argon co2 will give you a better weld and it seems easier to weld with.

no longer a series, but still 1.3 turbo.

Panels i use co2/argon mix. Ally i use pure argon.
And the Machine-mart bottles are the best I've found.

Two things are infinite: the universe and human stupidity; and I'm not sure about the the universe.

mild steel argoshield 5 for a perfect job.

but co2 if your good with a welder

Pure co2 lasts alot longer but if you want a nice weld and/or better penatration on thicker materials I'd use the argon/co2 mix. Pure argon is for TIG welding.

Its only a bit of metal. If it blows it blows!

i use a hooky boc bootle of co2 personally, most people i know use argoshield light (co2/argon mix) but they need a different reg aparently, so i havent swapped over yet.

big bottle of co2 will last a really long time..... like a week or so of welding everyday, and only costs about a tenner to replace. argosheild doesnt last as long and is more expensive, but it a lot better tbh.... anything really important, (ie seatbelt mounts, cage plates etc) i get a mate of mine to burn in (better operator, more powerfull machine, and argoshield)

And on the 7th day........... God created turbochargers!

Argoshield TC is best. Its a mix of CO2 and Argon. Its an inert gas and is why mig is called mig (Metal Inert Gas) CO2 alone is active gas and the welding process is therefore called mag (Metal Active Gas). There you go what a load of bollocks

I seriously doubt it!

cool, well it was payday today so i'm to machinemart tomorrow afternoon to pick up a 130A turbo mig and some gas so i can get some work done over xmas on my shell.

I'll grab some of the mixed stuff for now as i doubt i'll be welding any ally just yet

grumble grumble...no welders in stock at machinemart untill the end of jan, unless i want to pick one up from scotland!

Anyone know of anywhere else in the midlands i can get one before christmas for under £200?

try these people i think thats who i got mine off at a show once
