Hi guys,
I have a chinese welder, its a WSME 250. I have bought a foot pedal for it...... For the 2nd time.... First one arrived without any electronics inside, basically was a empty metal box. Now this one arrived with 7 pins connector... My machine uses 2 and 3 pin connectors.
Well basically I wont loose more time buying another one and hoping that they will ship me the right one... To stuff get from China to Brazil takes a lot of time, like 60 days, most of it due to Brazilian customs. Well I will not waste time complaining about this thing now, its just better get it done
So I open it up, I know my model of welding machine uses 10k pot pedals, fortunately the foot pedal is the 10k.
On this 7 pin connector they only use 5 pins. 2 for the torch trigger, witch is easy to solve it because they don't neet to be wired in any certain way, and 3 coming out of the pots.
The pedal have 2 pots, 1 on the front of it and the other one is the one inside that have a pinnion it so when you press the pedal it spins on the toothed rack, witch is just a timing belt attached to a piece of steel.
Looking from the back of the pots with the contacts facing down, on the pinion pot I have, red - black - red wires. And on the other one I have none on the first one, yellow and red.
The last red wire of the pinion pot is wired to the first connector of the front pot. The middle black one and the first red go to the connector. And from the front pot on the middle contact is a yellow wire that goes on the other remaining pin of the connector...
You can see it in the picture to understand better.
Well the problem is, how do I measure the 3 pins on my welder to know where each wire should go.
How to know what to look for on the meter to figure out the right way to wire it. Also IF that is even possible.
I have the picture of the welder as well, also you can notice the twisted red and yellow wires coming from behind that are wired to a switch witch is the torch trigger
Note: I decided to post this here and not on a welding forum because I have noticed by the years that there are people here that have more knowledge on electronics then there.
Thank you anyone in advance,
Gustavo
