Lincoln squarewave tig 200 momentary switch

[chevyracer8262]

I know I can buy a momentary switch for around $100 but I can't justify spending that much money on one qhen I already have the major components IE sheilded cable, 6 pin connector and goot momentary button. Could someone please tell me or provide me with the diagrams for what to use to build a custom momentary button setup for my welder? I've been looming and the only thing I've been able to find online is how to trouble shoot the foot control

Really simple. Just use the same two the pedal uses to close the contactor. Ring pedal out with ohm meter and find the two that close and open when pedal actuated. The schematics of course are all over the net.

There is a connection diagram inside the lincoln foot control.
If you use a shielded cable only connect the shield at the plug end. So any noise the shield picks up is drained to the case ground and can't get onto the wiring.

Switch goes on pins D & E.

So if I'm reading that schematic correctly I should need a 10k resister between pins A & B then the Momentary button between pins D & E if I'm correct

I doubt that. Your wiring just a contactor control. Connect it to D & E and see what happens. When you short those together gas is coming on and arc initiates and amps are on the encoder dial.

depends on what you are trying to do. A simple arc start switch you will not need a resister. As the welder auto detects the resister and will now look for a signal voltage.
So a simple Arc start switch just closes D and E. A,B, C, are left open. This way current is controlled by the panel knob. A full remote control will have a switch at D & E and a potentiometer across A,B,C.

Thanks to everyone one for the info, the not needing any resistor and only needing to install the momentary switch between terminals D&E was spot on. I rigged up a temporary momentary setup and it worked flawlessly all evening welding on my truck bumper. Tomorrow I'm going to build a quality arc start setup.

Goodmorning everyone
I also have this problem, thanks anyway for the explanations.
I would like to ask how do I find D and E?
pin side or solder side?
thanks for your help me

PIN side but be sure what the schematic is of. Some are the end of the switch/pedal and some may be of the machines connector.

This is facing the machines pins. The plugs from switch/pedal would put D & E on the other side. Keyed at the top.

Daniel thank you very much!!

hi all
as recommended by Daniel, I did the check, the connection diagram 6 pins plug, must be seen from the soldering side
thank you again
