    Bought a new welder, ?\'s on gas bottles.

    First off I just bought a Lincoln Squarewave 175 Pro. It will mostly be used for mild steel and ocasionally alum or stainless. Ive been told to get a 92/8 argon mix. Does this sound right? Ive never tig welded before so i want to be sure.

    Second, what size bottle should I get? This will be used as a personal use welder. (no major production) Is it better to buy or lease? What should I expect to pay to buy or lease and for refills?

    Thanks for your help.

    I use straight Argon. Helium is better at heat transfer. I sometimes use it on thick aluminum, like when fixing cylinder heads. At 8% I can't see it being much help there.

    The bottle I have is a 300 SCF. I have to fill it about once a year. $80-90 each time.

    Own advantages:
    Can take it anywhere to have filled.
    Can move with it out of current vendor's area.
    Own disadvantages:
    They fill your bottle, no exchange (Some exceptions)
    You're responsable for the hydrotest.

    Lease advantages:
    Exchange for filling.
    They hydrotest.
    Lease disadvantages:
    You don't own anything
    Can only move with vendor's service area

    Cost is usually about the same either way. I have 99 year leases.

    I lease my argon and oxy/acetylene bottles. It's much more convenient and no waiting for refill, just pick up new bottles and go. Granted I'll be here till I die so moving isn't an issue.

    When I first got my cutting and mig outfits I knew very little about welding. I went to the local welding supply/gas supply shop. Told the guy behind the counter what I had and what I'd be doing with it. He hooked me up with exactly what I need. Most reputable welding supply houses employ certified welders that know their [darn]. Find one and get on a first name basis with him and he'll never steer ya wrong.

    You use Argon/CO2 for mig welding.

    You can't use CO2 for welding aluminum. Well I suppose you could but it's not recommended.

    This is a tig machine, not mig.
