80/20 ain't it Jim? That's wot I use.Probably not but if their WPS is written around the wrong gas (luckily I didn't specify the gas) then they don't really have an option but to change it.
also the 80-20 gas mix does have a percentage of o2 in it as part of the co2
True
I'm not up on the designations (M numbers) but it is supposed to be run on a true 80-20 mix.
Air Liquide 20% mix is not a true 80-20 mix, it's 18 argon 2 oxy 80 co2.
Basically you want Weldmix 210 which is a true 80-20 mix with no O2.
