welding 4130 1 5/8 x 0.83 tubing

I have a Precision Tig 225 and will be welding a rear frame section for my fat tired street car project. Will ER80SD2 1/16 diameter work and can I set the machine for 100 amps with the foot control all the way down? I have a #9 torch with 1/16 tungsten. Is there anything better for this application? Thanks

That sounds about right...especially for joints with any gap at all...you may need a little more on certain tight joints and you might need to go up to a 3/32 tungsten ...100 amps is pushing the limits for 1/16.

you will be using your foot control either way and making adjustments as you go....the first joint will tell you.

good luck,
jody
