    Re: Learning to TIG

    I use a form block cut in half with a little s curve. Spin the wire slowly as you draw it through, works great for hinge pin stock, will let you know about .030 wire. Will try my setup on some safety wire and post a picture.

    75/25 on stainless mig will likely disappoint. Good luck though.

    Yeah, LWS suggests trimix, thinking helium is the drug of choice. Not happening anytime soon, will start with 75/25 on carbon steel and work on some shopping container repairs.

    Shipping container repairs will probably use the MIG gun. Here is more stainless TIG with oversized filler. You can see my straightener cut from a chunk of nylon. Pretty simple and works ok with safety wire so I will probably run what I have. Name:  549E958E-1E5C-4714-B6B4-793106FC2CC0.jpg

    Re: Learning to TIG

    Here is the project. 1/8” alloy unknown. I am pretty happy with the autogenous top face. A little sugary on the back since not setup for purge flow. The rest was looking pretty gnarly, grinder might clean it up enough.

    Re: Learning to TIG

    This is made of scraps from the pile so used drop from the top frame as feet for the steel stud legs. 1/8" stainless angles TIG brazed onto the 24 gauge galvanized sheetmetal.
    1/16" silicon bronze filler.
    3/32" tungsten, 2% dedicated.
    15 cfh Argon.
    Have fooled around with sil/bronze in the past with mixed results. 60 Amps seemed a good level but the 1.5/ sec pulse made a big improvement. Really like this new machine!
