can yo use argon to do mild steel welds or do you need some co2 in it

ive just ran out of co2 and need to finish doing the sills on a mitsubushi shogun asap

thanks

 

[madkayaker]

yes you can

 

[s410man]

as good as co2 or just can be used

thanks

Argon will give you a much steadier arc at low volts than CO2, it'll run a bit cooler and allow more control using wire speed, but the welds don't flow and can end up being a bit pointy. (Argon/CO2 mix gives the best of both worlds).

See http://www.mig-welding.co.uk/welding-gas.htm for an experiment.
