A pal is slighty disabled in so far as an accident left him with damaged tendons and nerves in his hands. He finds it hard to feed a TIG filler rod smoothly. I was thinking of ways he might be helped, and I thought of something like a mastic cartridge gun, but much smaller, that fed a rod as you squeezed a trigger, holding it like a pistol, with the rod being fed in a similar way to how the piston rod is moved by the applicator trigger, as it pushes the plunger in the mastic tube. Before I try and re invent a wheel does anything like this exist, or does anyone have any other ideas to think over?
I myself, as a newbie TIG welder, find manipulating a filler rod with gloves on tricky, I might try something similar for myself :)
Thanks for any replies.
