Syncrowave 300 not working

[dontbuyitbuildit]

Hey all, i just picked up a older syncrowave 300 its a big unit, it also came with a coolmate 12 it has a water cooled torch, i pulged it in and everything comes on the fan the coolant pump, but it will not strike an ark. I do not know the history of the unit, i do know it does not have a pedal, aparently the pedal was optional. Does anyone have any info on this unit? I could use some help gettin this one goin! hopefully i can get it working

Thanks!

Flip the contactor control switch to on or panel. Flip the amperage control to panel. Then strike an arc with the tungsten. Be careful, with this option turned on the torch is live all the time.

Both switches contactor and amperage are in the pannel position, and still will not arc, is there any way of testing voltage or ouput to make sure somthing else is not wrong? thanks

See if it will stick weld.

Check to see if the cables are continuous with an ohmmeter. Could be that simple.

Unplug it, take off the cover, and see if anything looks wrong.

Well i tried to stick weld, and no good.. i put a volt meter between the "work" post and the "electrode" post NO output voltage, if it switch the Ac/Dc lever the meter switches from ac to dc but still no output, the cooler is running fine, and the fan is running fine, so there must be 110 voltage in the unit the board runs on thats same voltage so the board must be getting power.. any other thoughts? i have to covers off and everything seems to look fine, nothing burntup, broken corroded etc.

Did you reset CB1 circuit breaker?

[dontbuyitbuildit]

were is the CB1 breaker located? the only breaker that i see is the 115v control circuit breaker is this the one your refering to? it is located under the hinged door near the 115v duplex plug. if this is the breaker your refering to yes i pressed to reset that one but it is not labled CB1

FYI: if it helps the serial # of the unit is : JH152089

[Dipsomaniac]

That is the one. If that circuit breaker trips it kills the control power to the panel, but of course it couldn't be that simple...

[dontbuyitbuildit]

yea that breaker is not tripped, so any other thoughts? any way of isolating problems?

[dontbuyitbuildit]

Any thoughts on how else to test this unit, could it be a board problem, a fuse or something else? im new to this welder and dont know too much about it. so if anyone has any diagnostic pocedures, send em my way! thanks!
