Wp20 short cup

admin

I have a wp20 that i need the smallest gas lens/tail cap possible for a rollcage top weld.  My button back standard gas lens is to big by a tiny bit.  What parts make the smallest wp20 torch possible?Syncrowave 350Coolmate 3Millermatic 251Spoolmatic 30A

Reply:Im welding the outside of a tube between a cars roof and the top of a funny car cage.  I might just have to cut my cup, but i was hoping that there was another option.Update, i tried removing the cup totally and running it with the tungsten in really close, because of the very confinded area it worked great. Who woulda thunk.Last edited by n20junkie; 02-03-2011 at 12:41 AM.Syncrowave 350Coolmate 3Millermatic 251Spoolmatic 30A
Reply:They make really short cups.  This one is for a large gas lens with 1/8" tungsten.  I have very limited use for them myself. Attached Images
Reply:Thats a short cup?  Id hate to see the long ones.  Thats about 1/2" longer than my normal wp-20 cups IIRC.Have we all gone mad?

Reply:Originally Posted by Oldiron2Are yours for the gas lens, as the one shown is? The gas lenses are larger than regular collet bodies, but the diffused gas flow is worth the size difference, IMHO.
Reply:I ground an angle into this cup (using a diamond burr, while keeping it wet) to get around an obstruction on a particular job, while keeping acceptable gas coverage.  I had to reach into an intake manifold runner, and weld on the inside radius of a bend.  It not only worked like a charm on that job, but I've kept the ground cup around and since that job, this ground cup has been handy on some other projects.  In another experiment, I also ground my own "shortie" gas lens cup. However the shielding on that is only good on some collet bodies (apparently not all gas lens collet bodies are created equally.)Since the most common kinds of cups are so cheap ($2-3 / piece), I can't think of any reason why not to grind one up, if the need arises and if one should be interested.  Diamond was definitely the way to go however, as any other method removed as much of the grinding stone as it did of the cup material.
