For optimum results on tubing isn't it advised to back-purge the tube with argon to reduce sugaring?

Yes -- on HEADERS etc.... but of course not if you're building a roll cage. So "it depends"....

On headers etc you want smooth flow which means keeping the inside of the tubes smooth. Sugaring also leads to cracking and corrosion. Purging also gives better penetration.

Notice the WIRELESS foot control??? That is why I bought one at SEMA a couple years ago...

We're working around various "stuff" --- we're not usually sitting at a bench welding all day. It's just one LESS cable to mess with. I love mine!

Since magnets are taboo........

I'd be very interested to see what your "must have" and frequent use clamps and positioning tools are.

ANYTHING THAT WORKS.... weights... clamps.... anything and everything that you can use to hold it long enough to get a couple tacks laid on.... and then you can reposition - or re-clamp the larger piece.

Sometimes I've welded on pieces so that I can clamp a larger "piece" -- then grind them off...

You really just need to be very flexible and very imaginative!


I also keep a nice piece of copper -- about a 1' long - 2" wide - 1/2" thick... it's not only good for a "weight" it also acts like a good ground conductor from the metal table to the piece.


WHAT DO THE REST OF YOU DO????

And a potential heat sink.

Alright, I searched for the TIG 101 thread and couldn't find it. So tell me what is best to clean metal with before welding. Thanks,
