So, I bought a decent foot pedal for my Parweld. Therein lies the snag, it is a really decent pedal with a cable to match. Every time I tried to use it I would spend more time struggling to keep it in position than the actual work would take. It is a thick, heavy duty cable which would be indestructible in a workshop. A complete pain in my place. So I ordered a length of really nice flexible seven core but it is signal cable: So, this is my question, which wires carry the most amperage? The on/off is simple but the pots? Any and all suggestions gratefully received.
