These pictures are of the rack I made to use 2 lb. spoolgun spools to dispense short pieces of small diameter filler wire for tiny TIG welds.

I have been trying to figure out how to use spoolgun spools for short
pieces of small diameter wire for TIG welding.

After buying a real wire straightener off of eBay I finally figured it
out.


The wire guides are 1/2" bolts with 10-32 nuts TIG brazed off center.
A 1/4" x 10-32 screw is loctited into the nut.
You rotate each guide to adjust the amount of deflection you need to
end up with a straight wire.
The final guide is a short piece of 3/8" square stock with a 1/16" hole
in it.

The eye screw keeps the wire feeding into the guides.
The spool itself is kept from free spinning by tensioning the axle bolt
with a nylock nut against a lock washer.
There is also a nylon washer between the the spool and the wood to
reduce friction.

My rack has 5 spools.
0.035" 4043 Aluminum
0.047" 4043 Aluminum
0.035" Silicon Bronze
0.024" 308L SS
0.024" ER70S-2 steel

This will go on top of my TIG machine.
Just grab the end of the wire with pliers and pull out a short piece,
snip and there you have it.
