changing wire size

They have been around for many years, and no, this one is new, and is very handy in any shop where you want straight cuts fast.

and here is what it produced...

a closer view...

Speaking of O/A torch tractor...here's something I did with mine...
I tied my spray arc torch to it, in this fashion.

I also used it for a TIG weld operation years ago, using a wiggler to oscillate the arc. Worked great.

Bob ,Rodger, and Zach, You would be supprised what you can do with mig wire and a tig torch.
I guy I worked for years ago hooked up a water cooled tig torch to a Buggo o2 / c2h2 torch tractor, behind this he had a mig feeder spooling in filler wire. This rig made some impressive welds, but only on flat straight stuff.

That will be hard to get by the "wife test"!!

As Rocky D said,

zip locks are good idea. I also have some "pretty" tight containers from new wire that I use. I keep mine inside, rather than in the garage (more stablte temp, less condensation).

As to the reel ends ... the last 10' that the rollers can't push thru the torch leads ...

They pierce the skin real easily (experience) so maybe you could sell them to an acu-punctureist.

Or maybe offer them to some "TIG'er" (GTAW) for filler metal?

I cut the ball at the tip and rewind it. Just because its in the gun doesn't mean its not usable.

Growing up I was always using bailing, and telephone steel wire or copper and aluminum wire for some use other than original purpose. Haven't found side use for welding wire as too thin and brittle. I always wind it back on reel or toss spool ends. If you're using knurled drive rollers look and feel for indents in wire before saving or just toss it.

Rewinding wire

Thanks, you guys, I always appreciate the help, Tim.

The 2# spools will fit nicely in a zip-loc bag, and the only thing I would add to what has already been said, is be sure the wire is not bent when you cut it at the tip end...the extra force applied to the spool rewinding it could cause the wire to sink below the surface wrap on the spool. As you rewind the wire, it should retract smoothly.

[Bob]

The wire will have the same desire to unwrap as the new spool did. So cutting or rewinding, don't let it get loose. Most spools have small holes near the rim. You can secure the wire by putting it thru and making a shape bend. I would avoid tape because of residual glue.

I always rewind my spools. Whenever we change from bare wire to flux cored wire, I snip the end by the tip and rewind the entire thing. Keep the rewound spool clean, dry and rust free.
