Project Tig Pedal

admin

After a few weeks of diligent practice using the controls on the torch handle of my new Diversion 165, I decided to try my hand at making a foot pedal.  Finally finished it tonight, and tried it for the first time.  What a difference in control!  Now, I don't have to juggle the torch and controls at the same time.  Although I did see improvement during the time I was trying to learn, the torch controls forced me to hold the torch without any variation.  I realized a marked ease of use on the first bead I ran, tonight.I added a DPDT switch to the pedal, so I can start at high or low amps, thus allowing me to pulse at high amps as soon as the arc starts.  I, also, incorporated an RJ-45 ethernet jack on the pedal, same as the one on the front of the 165, so I can use a standard 14' shielded cable.I chose a wood base for the unit to simplify location and assembly of internal parts.

Reply:very nice!  Great ingenuity!
Reply:This is great! I will be doing something similar and will add it to your post when I get it done! get a collection of DIY peddlesweldoride - about your hot start function. in what conditions would you want to pulse the maximum amperage like you described? I have tig welded a fair amount, but was never tough this technique.

Reply:Ah, that makes sense. Thanks!
Reply:Nice - I could see how that "hot start" feature could come in very handy!  Wish my TIG foot pedal had that.  I also like your string and pulley linkage design.
