Automatic Tig Filler Rod Feeder

The tig cold wire feed process is suited for automated and manual tig welding applications.

Automatic tig filler rod feeder.

I made this tig rod feeder to serve as a prosthesis for a welder who can no longer manipulate a filler rod into the puddle due to a stroke that he had a fe. Adding cut length filler rod to the weld puddle is labor intensive expensive and wasteful. Cold wire feeders use standard spooled wire which eliminates stub loss associated with 36 914mm cut length welding rod for longer arctime and 30 increase in productivity. With the feeder comfortable in your hand advance the wire by rolling the rubber wheel with the tip of your index finger.

I have built several wire feeders for tig filler delivery for aluminum and other materials. The new profax px20tig cold wire machine will increase tig welding productivity by eliminating time consuming arc stops and starts common with cut length rod. I ve been learning to tig weld and one of the tricky parts to master is feeding the filler rod with my non dominant hand. Suitable for tig wire diameters 0 8mm 030 to 3 2mm 1 8.

It s been a while since i ve done the challenge so i thought i d see what i could rustle up in way of an automatic rod feeder. Tig rod feeder bin wall challenge. I made this tig rod feeder to serve as a prosthesis for a welder who can no longer manipulate a filler rod into the puddle due to a stroke that he had a fe. Save 20 40 on filler metal costs because spooled wire is less expensive than individual cut length rod and the unused rod end waste is eliminated.

Last edited by goodhand. I had this one aluminum job that i could have a part loaded welded and unloaded in 45 seconds. Virtually all of the wire is consumed can be held in either hand comfortable lightweight and compact one tig pen for any diameter wire from 030 to 125. Hold the feeder like a pen or pencil.

There are serious benifits to this kind of system. The tig pen is the first manual welding wire feeder that truly makes sense. However you need to sync the filler timing with the hi pulse time and your travel speed to get optimal results. Insert the tig filler wire from the rear of the unit not from the front.

Total control of the filler material is now possible. The powerweld tig finger feeder tig pen smoothly feeds tig filler wire using just your index finger. Tig finger feeder is 9 25 inches long and fits comfortably into your hand.
