Co2&Argon

[GeorgiePorgie]

This can't be right can it? Toolstation are saying.....

For use with Mig welders. Use CO2 for steel and Argon for aluminium.

May be a typo on their site and the wrong image...

For MIG you can use pure CO2 for steel, or an Argon.CO2 mix...

You have to use pure Argon to MIG Aluminium, but the disposables don't last very long at all...

Arrrgh it just me,havn't had me weetibix yet.

I know the disposables are a dear way to learn welding but as I have not managed to find a large bottle as of yet I'm eager to get stuck in,just waiting for the damn hose to emerge from a ebay seller.

What about regulating the two ie 80% Argon and 20% co2 will this last a bit longer?

Sadly not...

You have to screw in the regs almost all the way to get enough flow so setting up a flow meter system on disposables you'd use a full cylinder setting it up

If you want the gas to last longer try getting 600g CO2 disposables, not all manufacturers make them though so you may have to get a different reg...
