Tri mix

[mklewis]

Would a tri-mix show the best results laying beads on steel?

No. Probably should use C-25. Tri-mix is more for stainless steel.

This guy has some BS and wild claims too. For example, Cobalt Boats (premium runabouts) are built in Neodosha Kansas; I've love to have a piece of their boatbuilding business in Kansas.

Tri mix was used to reduce divers decompression time but isn't often used.

Where exactly, in the mig welding gas section, did you detect the BS? I'm sure Ed (and all the major gas companies) would like to know, and perhaps you can take up his $5000 challenge on their behalf!

Maybe I overspoke, but I generally take the lone voice swimming upstream with a grain of salt. I see lots of documentation and MIL-SPEC approved welding procedures that specify C-25 for mild steel. MIL SPEC does not allow short circuit transfer, so it is generally spray transfer. Even this site seems to generally agree on C-25 for mild steel. Maybe that's because as Ed aluded to CO2 is cheaper than argon. And Cobalt does make boats in Kansas.

Ok, I was just wondering, because Ed does have a lot of expertise, especially on trimixes, and much of what he has written (not on the web) is available through the AWS, and they don't generally support BS. Much of Ed's web site is one long infomercial which tend to drown out a lot of excellent learning material on there, and his arrogance leads a lot of viewers to attack.
