Using CO2/argon instead of CO2
I am half way though welding ons some chassis bracing....My darn CO2 cylinder has run out!
I have half a cylinder of CO2/Argon mix from machine mart sat in the garage.....can I continue welding with that, or will the welds be weakened?

I think you will find it will put a better weld down as I find the argon/Co2 mix much easier to weld with. As for strength 99.9% of fab shops I have
seen use argon/Co2 mix for welding carbon/mild steel.

As above - i always use CO2 / Argon mix as i find it much better for mild steel.

same here, that's why I'm using it Argoshield is what the gas I'm using is called.

I thought you were building a garage Mr Whippy?
 Don't tell me your adding it to the concrete mix to make it go further?

Welds are most likely to be stronger and cleaner....

Once you have used Argoshield you will not want to go back to co2 unless you are very tight.

CO2 is usually used on thicker section steel for more penetration, you'll do a better job on chassis section with the argon mix. You may find
you need to alter your settings a bit, wire speed and voltage run lower on mine with argon/CO2 than pure CO2 and there is a lot less spatter.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

I learnt to weld with Argoshield, and was startled when I eventually tried CO2 - everything was so much more 'lively'!
The argoshield gives a 'softer' arc that's pleasant to use, and negligable spatter (as pete says).
You will have to mess around with settings though (maybe turn the wick up a bit).

On my welder the wire welds itself to the tip when I have tried to use argon / co2. Shame because it gives a lovely stable arc.

I ran out of Argoshield and was forced to use CO2 - I was surprised how crackly it was - a much harder arc.
Cheers,

co2/ argon mix all day long,co2 only gives a colder weld and more brittle

I quite like a CO2 shield. But then that's because my Mig90 is a bit marginal on penetration and CO2 is better in that respect than Argon/CO2.
With Argon/CO2 I get a very nice looking weld sat on top of the piece to be welded!!!!! And that's regardless of wire speed / power settings....

Sounds like the wire speed is too low.
