Argon/CO2 mix

[kenmac]

Can anyone help me with this, for car body work welding which would be best 5% or 20% Argon / CO2 Mix on my 130EN.

Cheers

I use a 95% Argon, 5% Co2 mix with 0.6 wire, which I find is ideal for thin car panel work, for anything thicker than say 1.2 mm then I would be looking towards a 80/20% mix and 0.8 wire.

5% CO2 is 93% argon and 2% o2.

20% is 80/20mix.

The 5% (argoshield, ferromax 5 Cougar) will work best. The 20% will work about the same with maybe a bit more spatter.

The disposables are 80/20.
