Shorting the caps if there charged would create a very large spark, probably lose the end of the screw driver and the end of the cap terminal. just touch the mig wire poking out of the end of the torch down to the work piece. If the caps have failed there is usually a sign of them leaking or...
The 10 position switch will work fine. There would just be no `0` position. The switch numbers on our switch are the same as your salzer switch so just a straight swop. You would need to drill a couple of holes to mount the new switch on the front panel.
The 3 bridge links on the salzer switch...
It has 3 poles. depending upon how your machine is configured, you either connect each phase onto each pole of the switch from the contactor in the machine, or you link the three poles together with some flex to create a star point.
Hi. The company I work for manufacture welding machines in the UK. If you have 4 wires coming from each coil of the three phase transformer in your machine, the switch is what we call a shuffle switch. We stock a 10 position switch which is a replacement for the salzer 10 position switch and it...
Hi. There is a black relay on the PCB with two thick wires on top of it. If you connect the brown solenoid wire to the bottom relay connection with the solid thick wire. The blue solenoid wire needs to connect to the blue neutral mains input but after the on/off switch. regards Les
Hi Darren. Did you get the reply to the email you sent me. I have described exactly where to connect the solenoid wires to in your machine. If you have not received it, let me know and I will resend it. Regards Les (Yor************)
Hi greg.
I have come across this problem a couple of times before. The control pcb does not have much in the way of protection on the trigger circuit, so if one of the trigger wires shorts to the welding positive it takes out the PCB. Symptoms vary depending upon which components fail on the...
Hi. I have repaired quite a few of these PCB`s in the past. from what you describe and previous repairs on these PCB`s it does sound like it is the PCB that is faulty. Faults vary on the PCB from the power supply failing to the I.C or a transistor failing, all which can give the same sympton of...
V groove rollers are for hard mig wires,
U groove rollers are for soft wires, (such as aluminium),
knurled roller are for flux cored wires.
hope the info helps.
having any of the different version PCB`s fitted in your machine would not cause problems because the PCB`s are all compatible with each other. Most likely that the PCB is faulty still.
The number is etched on the track side of the PCB. There have been a few different versions over the years. The number would be either W22E or W10M-3, or W10M-4.
Solder joints on the W22E version were a common problem.
The wiring to the connector looks ok from looking at the photos. The white and blue wire on pins 4 and 5 on the connector are the supply for the PCB. The contactor goes to pin 9. I would say the PCB is faulty from what you describe. The connector is driven by the triac on the PCB. It could be...
Hi Chris. It looks like it has blown a component off the pcb where the scorch mark is. Probably a smt fuse looking at what I can see of the circuit. It looks to be part of the power supply for the machine. If it is a fuse then there will be other faulty components that have caused it to blow...
The PCB in the murex tradesmig are quite straight forward to repair. Done loads of them in the past. What is the fault with the PCB / machine. PM me if you would like me to repair it.
Hi Chip. The oxford oil cooled set only use two phases of the 3 phase. If you connect one phase to the 0v terminal and another phase to the 400v terminal, and the earth, green/ yellow wire to the earth terminal. The third phase is not used. It does not matter about which colour wires you choose...
