co2 vs Adams Gas 5% Co2 / Argon Mix vs Adams Gas 20% Co2 / Argon Mix

As the title says, I'm looking for torts on the above gases.
for reference id be looking at MIG welding box steal around 2mm and sheet steal 1-2 mm

CO2 will work, but Argon/CO2 is much nicer to use and gives smoother welds. 5% mix for that sort of work.

As @Misterg says, 5% CO2 in Argon will be best for anything upto about 6 or 7 mm. Thicker than that you'll be better with 15% CO2 (and possibly a bigger welder! ) Not sure about Adams but Hobby Weld add 2% O2 which apparently makes for less splatter.

@RWD3M I had a look at Hobby Weld, bit expensive for me as just a weekend warrior, 5% it is
