miller dynasty what is precharge relay

[coppercone2]

god fucking damnit, something is still wrong. I put the right transistors in but I still have a low bus voltage. I wonder if its that UC switchmode chip, or the relay. It won't click.I gotta test more shit


fuck that guy that wrote the wrong transistor. I remember now, it was 2x 06 transistors in a row (the first two i checked). and fuck open office for not making a auto save of my damned transistor ID document that lead me to shady information online  . I renember I thought the first one would be an 04, and it was 06, and then I thought the second one would be 04, and its 06, and then i thought wow this has alot of 06 in it when I started making my god damn document

He was whining that people did not support his project or some shit like that. I wonder if that was misinformation put there on purpose, it might be a spiteful bastard

what the hell did that current break. 


On the plus side, I realized it would have literarly blown up again if something else was not broken, because the first time i tried to power it again, it had the SAME thing that caused the fault.

is this what SMPSU experience looks like? ugh . My little power supplies you put a transistor backwards it might not work. this one explodes. will this knowledge ever benefit me?

and fuck miller for scaring people into thinking they can't post schematics, this all happened because of cloak and dagger bullshit caused by lawyers.

you would think they want their machines to proliferate and be known to be reliable instead their focused on corralling their dependent customer base, which none the less has the option to choose another manufacturer that fucking does the same thing. I wonder if the evil master plan was to wait till all the old machines become too old to repair so everyone is forced to buy their new ones, too bad power electronics decreased in cost and proliferated so much that the power levels required for any reasonable hand operated welding machine are now within the range of basically a third world nation with enough app notes to allow for sub par manufacturers to develop welding machine, a ubiquitous solar inverter generates more power and appears to be more reliable. I think alot of these proprietery high end 'power electronics tool' companies are going to get washed away by repurposed EV and solar parts within 10 years. I think the old mentality was that their safe because noone but a factory would have similar devices, now my basement and car have literally higher power more complex circuits, and like 20% of the worlds population is bound to follow within a short period of time, all similar circuits from various manufacturers that will literally be everywhere with advanced open standards required for safety and adoption for such uses.


I wonder how many years off an advanced open TIG welder project is with how much power electronics technology is proliferating. I think they basically have drop in replacement PFC modules at the correct power level now (usually considered to be a CRUX in this sort of project). Actually the first two stages basically turned from weirdo unobtainable to drop in (AC-DC and PFC).
