hi guys
im in NN5 Northampton..

i have upgrades to an older murex 200amp , 240 volt welder,
ive not used it yet as i picked it up 2 days ago..

i would like to find out which model it is
and how old it may be ,it seems to work well



i will get some more pics today ..

Oldie but goldie! Very old but very good piece of kit.

thanx for the reply
any ideas which model it is ..?

heres a few piccys of it



what does this 1-8 selector switch do ...?



internal stuff ..there looks a lot of it ...





wire and motor

No idea of the model I'm afraid. Doubtless someone will be along shortly who knows. These older machines were properly built though, it should give you years of service.

it seems like a proper work horse ,
not much has been changed by the looks of it,
ive been round all the connections tightening them up and lubed the motor and cleaned out a lot of workshop grindings and debris ...

At a guess.. Your 1 to 8 switch is power and the WSP dial is wire speed. Looks to be a well made bit of kit. Have fun. Or.. more to the point, give it a go at different settings for a 'feel'
Again, since your pix are a bit fuzzy.. the other two dials above the WSP one might be for spot/tack timing. I have those on my Kemppi, but never use them.

i think your about right,

having a google, about rotary switches....it is a power switch,
it has some thick copper wires dissapearing into the main windings,


the top knob 1-10,
appears to have a pulsing effect on the wire driver,
when switched off [0] the wire remains at a steady speed...

2nd knob controls the wire speed....although it need realignment ..

3rd knob is a power switch,probably a fine tuning one..


having checked and serviced the machine ,..i may well get to try it all out tomorrow ....


thanx for the answers ..i look forward to any more that people have

The top one may also have a latch setting. i.e. squeeze the trigger and it feeds until you squeeze it again. Saves having to keep the trigger squeezed down on long runs. It might also have a gas/no gas setting for use with flux core wire. Have fun.

Switch cleaner?

^ it does look a bit pricey...
so does your provide the initial power adjustment to the machine...?

It selects 230/380 single or two phase input. In effect, the On switch. From time to time it will not turn to Off.
