Has anyone know how to wire that rotory cam switch to up amps or have a wiring diagram please
I'm not sure of your exact model, but maybe the schematic is on this list:
Can anyone help who knows where i can get the switch from or who got one please
Do you have an exact model and serial number for the welder? ( photo of the data plate may help )
There are a million different switches, and two million ways of connecting them to the transformer taps. Replacement switches are identified by a manufacturer and a type number. This should be printed on a label on the switch. They are made-to-order. External jumper clips or wires may have to be added by the user. You need to know how many positions the switch has, and how many segments. There are many variations. It is a minefield....
An alternative which is sometimes attempted by brave, or foolish, people is to open the switch and clean, lubricate, repair, or replace the damaged contacts or cams. This usually results in boing, ping, whirr, splat, as springs, contacts, and ball bearings shoot out into all corners of the garage, followed by the sound of much loud swearing.
TecArc in York may be able to help : https://technicalarc.co.uk or perhaps @NotANormalCoder
The above sounds horribly familiar...
As said, try Tech Arc (for an aftermarket switch) or the Service department at Wilkinson Star for a genuine part.
If you go genuine, it should be a very straightforward wire for wire swap.
Just make a note of what goes where and if any wires have lost their markings put your own on with masking tape etc.
If all else fails you may find the swich configuration on the circuit diagram which Cebora used to glue inside the side panel. If not it will be in the operating manual most likely.
