Snap start hi freq board melted resistor

[Cook county cummins]

Yes this is out of a snap start, not a snap start II, but in the manual it does not break down the hi freq board, but if someone has one and could measure the value of the r1 that would be a great help john.

Theres a pic of the whole board i had saved on my phone , ill get better pics tomorrow, theres 2 connectors on the right hand side of that pic. One 4pin connector and one 2pin, pic earlier in this thread shows it still in the unit with the connectors connected

Any of the miller techs have a guess of what the value could be, should i start high and see what happens i mean its already smoked so i only have a chance of making it work again and since otc will not give me any info i may as well start clipping resistors into the circuit and see what works...

My fluke only measures capacitance to the .0x if i put it on manual, if i leave it on auto it displays 2 for both of them so until i get a better meter on them wont know for sure if they are good or not but i may go up and buy another 330 for cheap and see what the caps look like in that one...

[Cook county cummins]

Sorry i just seen that the cheap cap is one more 0. I read it as .0024 not .00024 so yes that will not work, but im going to keep searching...

Heres the pic of the dripping from the caps going to remove and inspect behind maybe they were already replaced

[Cook county cummins]

Ryan your saying that the same mica capacitors in your machine have dripped resin? Ill have a pic up of mine in a sec...

[Cook county cummins]

Yeah i get the .0004 difference but thats why im here to see if anyone smarter than i can confirm that it will work or that it wont.. currently the hi freq starts the arc just have to be pretty close for it to jump. It was just a quick test when i picked it up. Once i get everything cleaned and re set...

$3.50 is alot better than $150 from miller

I was thinking of trying these...

What was the new part # i just picked up a 330 with the same cap(2 of them on the hi freq board that are leaking) would like to replace them, the 330 starts an arc still but just would like to replace them as im sure its not long before they cause a problem

[Cook county cummins]

Yes in all it looksblike the heat effected area is more than a few components but i figured if i get the r1 replaced with proper value resistor then i could test the rest or maybe it will just work after r1 is replaced...

[Cook county cummins]

Both the snap start and snap start II manuals dont break down the hi freq board. I also have the newest part # for the board if thats helpful to anyone who may be able to help. The otc par # is P10474L00 just trying to get him going on his welder. Lift arc works great though so if its a loss then he...

My buddy picked up a maxstar 152 with a snap start on the bottom of it but once we plugged a pedal into it no hf. So i took it apart to check the points and found R1 resistor is burnt along with a good size area of the silastic resin and possibly a few other components, but R1 is for sure gone can...
