Help a Genius Assemble his AlphaTIG Torch

Postby Chips O'Toole » Fri Mar 10, 2017 8:12 pm

My welder arrived Monday, and I finally got to fool with it tonight. I am trying to assemble the torch. I have a stupid question.

The torch is a size 17, and it came with three collets. The first tungsten I ground was 1/8", so I figured I would assemble the torch with that, using the biggest collet. When I tried to do it, the tungsten fit in the collet fine, but it would not go through the bore of the collet body.

What's going on? I just assumed that three collets with the same OD meant all would work with the same collet body, but I don't think I can get the tungsten through the body without drilling it out.

Is is a lens or gas saver style. You need to have the correct collet size as well as gas lens.

It's the basic torch and cups that came with the welder. Not a gas lens. The collets are fine. It's the collet body that's small. It will work with 1/16 and 3/32, but it's too tight for 1/8.

The collet body also unscrews. It' has to match the same size as the collet.

It could be the wrong sized collet for the tungsten, but you aren't supposed to drill anything. My collets are marked for each size up near the top.

One way to assemble is to remove backing cap/tungsten cover and insert collet, then tungsten, then tighten down the back cap/tungsten cover. On mine (cheap abicore binzel that comes with chinese machines) the back cap tightens and snugs up the collet and tungsten. If the back cap is on it will be hard or impossible to put the collet and/or tungsten in.

The collet fits fine. The collet BODY is too tight.

Does the collet for the 1/8 tungsten fit into the collet body?

For any given size tungsten you'll need a collet body and collet for that size, if your 1/8" tungsten is too big (in diameter)for the collet body then the collet body is for a smaller tungsten.
