Thought I Would Try This!!!

I have never been a big fan of torch mounted argon valves. I had some stainless steel plate, a stainless hinge and a small pneumatic valve laying around. I cobbled this foot operated valve together in about 1/2 hour. I needed to buy a few small brass fittings to hook it up. The other thing that is nice about this is since I eliminated the valve on the torch and was able to to use a standard #17 torch I was able to move the pendent switch up underneath the backcap instead of having it side mounted. I prefer it up underneath the backcap so I can control it with my index finger.

rahtreelimbs,
That is interesting. I assume you only do bench work as this would seem cumbersome for field work. You might want to get the patent started before someone steals your idea

Very nice though.

Jonathan.........I have a 15'x25' detached garage that I am working on getting a small fab business started out of. I have TIG welded standing up and sitting at a bench. I have several (probably too many) TIG welders so going with the conventional welder/foot pedal is never a problem. I like making my own accessories/tools..........give me some welding time also!

I really dislike a valve on the torch body!!!

First good luck with the fab business! I will offer any help I can. I can't fault anyone for wanting to make their own tools, I do it myself. I think this would be very handy and more efficient as opposed to the valve on torch body.

I will add that this TIG machine will only be used with a torch mounted amp switch!!!

I would be interested to see a few pictures of your application, if you can. Are you using a on/off switch?

I am using a Pendent switch. In this pic it is mounted on the side of the torch. This was one reason for creating the foot operated valve. The switch won't fit under the backcap with the valve knob.

That's a nice amp switch. Who makes it/where did you get it? No problems with heat?

You could get a foot pedal to use also.
Then you would be using all four limbs.

Mainly for what i do this wouldn't be practical but i do see a place for it for sure. I may have to build one for that just in case deal. Otto posted a comment on another thread about a jaw driven amperage control, may be able to do the same for a gas valve.
