The capacitors took a shit on mine causing it to consume too much electricity. I could feel the power leads to my shop service panel vibrating and getting warm. Took it to CK welding repair shop and they found the start up capacitors bad. Seems to do fine without them.
they call the capacitors a PFC, power factor corection, not all machine have them. my syncro250 didn't come with them, but my shopmaster does have them. pfc machine where marketed to the big shops that pay teired energy prices based on peak consumption, having a crew of weld machine arc up at once can csot a shit ton.
(talking 1ph 240) a machine with pfc, will draw a ton of power even at idle, iirc 30-40amps, but it will not need more than a 60a breaker to run all out. with out the pfc they run, 6-9amps iirc, but you'll need all of a 100amp breaker to run it balls out.
story; the shipyard i worked at had 2 transformers explode while i was there, one was a substation box thing, lost power to our part of the shop. i went out, reset the breaker, took less than 10 steps walking away and BOOM
. good times.
the other one was on a pole and shook the whole place and killed power to the entire yard. that was the only day we got sent home early.
btw, i'll mess with and try to fix just about anything. capacitors i stay the hell away from, i dont wanna die like that. everytime i open up the shop master to blow it out, when the air wand is next to them, i just think in the back of my head of the videos of guys in india touching the rails cars power supply. nope!
I had several feet of weld to do last weekend and I played around with the knob some more.
I more or less got it figured out through trial and error.
The confusing part is the grey and green rectangles on the dial. I think they suggest "balanced" but I'm not really sure.
Obviously my beads suck but this was all getting ground so I was just trying to get good build up.
grey and green rectangles
take a pic. there are allot of different panel layouts.
if your balance dial is labled 1-10 you basically leave it set on 3 for all welding. except for ac tig. ac tig you can run the balance 3-5 to ball your tungsten, but when welding you want it at 7-8. the higher the number the less it cleans but also the less heat input into the tungsten/ torch. i dont think the dynasty even lets you set it below 50%, #5. think of an ac wave form... as you turn the balance higher the wave, heat, going into your weld piece increases, the opposite wave, goes into the tungsten, but is also providing the cleaning action. you want as much heat into your weld as possible, and dial it back for the cleaning you need.
you can usually tell if someone has it set wrong by the white haz next to the puddle. looks close enough. the tighter the white line the better.
for learning ac tig, there is no better machine than a syncro and running green tungsten. everyone wants to use the dynasty but to learn they start on the syncro.
