Hi guys,
I think I mentioned I had a cunning plan to make my own TIG pedal in my post about the AIG TIG 200P earlier in the year. Well I just got it done and tested this week...
The result is yes you can modify a generic sewing machine foot operated speed control pedal to run a TIG machine, my TIG machine at least.

I scrapped the idea to include bluetooth wireless for now, can't justify the effort right now.

I also have the metal pedal for the 200P that is sold by AIG to suit it, but I really find it uncomfortable to use for long periods, so I kept on with the above plan to make/hack something much more suited to me and my small welding bench.

In short:
I bought the pedal for about $20AU from AliExpress (must have be a 'speed control' type not just an 'on/off' type).
Removed a couple of unneeded components with a soldering iron.
Added a micro-switch from Jaycar.
Replaced 2 core cable with some trailer wire (at least 5 cores needed).
Added a three pin and a two pin GX16 plug bought from Ebay.

Fitting the micro switch required a little thought (and an L bracket), as did wiring the plug pins to the right places on the circuit board.
I 3D printed the L bracket for the switch (but it could have been done with a bent bit of metal plate) and then epoxied in position.

I am really happy with the result and would do it again rather than buy the awkward heavy metal one.
This pedal is way easier to hold steady at low amps than the big one, and I can leave my shoes heal on the ground when operating it which is way less tiring.
The big metal pedal might end up on Gumtree now.
