Hi guys

I'm going to get a decent size gas bottle for my MIG before i start serious welding on my chassis.

What are people's thoughts on which gas to go for? Is CO2 sufficient, or am i better off with CO2/argon (Argoshield?) mix? I've heard that the mix gives better welds.

I use Argoshield Light, which is recommended for steel up to 3mm thick.

I found that it makes it easier to produce a good weld - I believe that plain CO2 is good when used by experts, but is hot and unforgiving.

I use the Air Products equivalent, Coogar, good stuff

argoshield light.......

cooler, less power, neater weld.

sorry for the gaps above ---

look in the yellow pages for welding consumables -industrial -----go and have a chat, as this type of supplier can sort you out with all types of gases , in proper sized bottles --you sign up to a contract which enables you to "hire" a larger bottle of gas , with an initial set up cost (£20-30) and then a small monthly feee (£4 ish)this type of bottle lasts forever ,( well you know,) and is infinately cheaper than forking out for the little bottles that last for a few strkes of the torch !
Hope this helps ,

Total welding amateur and been using Argoshield Light for a week now. Much easier/better welds than CO2 and less power. Got mine from local engineering co. under 'welding supplies' in yellow pages, set up my set for me as well and gave me an hours tuition! Cost about £30 to hire bottle for year, £25 to fill it, and another £40 for a new set of gauges.

your gonna go over budget ya tinker you....

£30 a year for a bottle? BOC wanted sack fulls for theirs,thats why i use co2 and they wanted a 10 year deal!

10-year deal! That's not the BOC I know and love!

Originally I set up a 12-month minimum agreement, which had to be direct debit. After that, I could return the bottle whenever I wanted, which was what I did with my TIG's argon bottle. I was pleased to see that they rebated my unused rental as well.

cheers,

David

That was a long time ago i tried it on with BOC so they must have changed policy,ps wana buy some wheels and a zetec?
