Thats indusrtial stuff right there.
I checked out the 252i which welds 1/2 thick metal.thats a keeper.
Keep in mind that welder has mig,arc and tig,the tig and mig needs different gases so you would need two tanks for optimum performance.With the tig really likeing the straight argon and the mig needing a mixture.You can run straight argon with a mig but it really burns hot.
