Probably, can you post a picture of it to remind me which one it is.

Been a few years, but here goes...
Turn PROG SEL to any number (not robot)
Toggle switch in PROG position
Each press of SEQ will move through weld sequence which is usually PSQ, SQ, WELD, HOLD, OFF, HEAT
Then use tens & units buttons to alter times
PSQ - pre squeeze = time to close tips
SQ - squeeze = time to squeeze parts together
WELD = time weld is on in cycles
HOLD = time for weld to start cooling (also known as forge time)
OFF = time before next weld allowed (used when repeating)
HEAT = weld current (normally a %)
Depending on model there may be H1, H2 (HEATs) or PULSE for various applications
Switch toggle back to run

Sorry no guarantees on the above, it's been 20+ years since I played with them

Found some info here to read and will have a look to see if I still have the schematics/drawings for the MP8

That's great. Thanks

Sorry, no luck with documentation for MP8, could only find stuff for MP16 & MP2000, looks like I can program & calibrate the MP2000

She is a British federal 65kva. I have her going but she isn't putting a lot of power to the tips. Any ideas??? Thanks

Is it a pedestal spot welder similar to this or a pendant (hand held) type welder?
