i can not view it. says admin privileges required. i don't believe the print is diy as i scanned it from a manual although it looks like it
i will as soon as i can but it might take a few days. mine still worked when one of those relays fell out. probably the spot weld timer that has never worked
Eddie, the motor is 110 vdc, shunt wound, 4000 rpm and it looks to have an epicyclic reduction gearbox.An interesting old beast!
There are two main welding transformers, are the secondaries in series ?
The inductor has a tapping where the capacitors are connected.
I like the wire-wound rheostat to control the speed of the ( AC ? ) wirefeed motor, and the gear-driven pressure roller. I don't think the pivot for the pressure-roller carrier is ever going to need the "brace" mod.
Ring Tech help they usually can helpI noticed the relay with the RS logo on, must be 'relatively' new because they were RadioSpares in them days
I did have a look at rswww.com to see if the number was still relevant, it wasn't which is a bit sad, I was expecting them to still carry it. They probably do but with a different part number.
Any ideas what the middle one is ?
Brilliant project though. The quality of the metalwork really puts the modern tin can Chinese stuff to shame.
Just had another play around with it. My spot timer is controlled by the relay missing its case, next to the empty space.sorry it has taken me so long to get back to this. just pulled the relay on mine. sorry no markings on it whatsoever it is the same in appearance to the black one next to it except it is 3" long. my machine will still work with this relay removed so i think it's the spot weld timer. i can't check that as it's never worked on mine
