Why would that prevent you from using your arc welder?


Now this meant he was using a constant current supply instead of a
constant voltage supply. And that meant he was welding in spray
mode. But it worked.

I think the TIG swings both ways , CC and CV since it's for arc welding
too - and even has spot welding settings .

Arc welding and Tig welding both use CC . Mig uses CV .


Next wild idea. Have not tried this, but you should be able to use
dual shield wire with your Tig welder. I have not tried that, but it
ought to work and give you a little flux to help with metal that is
not perfectly clean. It may play hell with your tungstens. The dual
shield that I have used worked well with CO2 shielding gas and spray
mode. But you would want to use argon with your tig.

I have used mig wire with a tig welder when I wanted a smaller
diameter rod than the tig rods I had on hand.

I've used 2-3-4 strands of .025 mig wire when I needed something finer
than the TIG filler II had on hand . Works swell . I never considered using
the flux core wire though . It's pretty brittle , might have fun trying to
twist a couple of them together - maybe some solid and some flux core ...



I do have some dual shield wire if you want to try using it with your
tig welder. I know some of it is .030 dia. Not sure if the other
reel is the same size. It may be bigger. I am sure you will be done
with this job by the time any package would get to you. But if you
want some. let me know. I got it at Boeing Surplus before they
closed up. I have several lifetimes supply.

The good thing is that I have options . Probably not a bad idea to burn a
few sticks of rod with the tombstone , there was a time when I was a fair
hand . Of course at that time it was my only option too .
This isn't a definite thing , but since he has no cheaper options I think
I'll be doing the repairs . Something else I've been thinking about , I
wonder if there was supposed to be a strip to double up the axle tube wall
where the brackets are welded on . Sure looks like a good idea to me , with
little weight penalty .
