Lincoln Invertec v250-s repair (precharging circuit / pre-charge resistors)

admin

Hello, I am posting for the first time. With the help of a friend, I set  out to repair a Lincoln Invertec v250-s MMA machine. The problem was  created by a welding machine maintenance center

When the station is turned on, it blows the lead regardless of the value  of the circuit breaker (16, 20 or 36A), I'm in Belgium. It does this  twice and on the third attempt the station turns on. When it is on, it  welds. We understood that this was coming from the capacitor pre-charge  circuit. One of the relays was welded inside (I put a photo).

We replaced it with a relay of the same value and we also replaced the  two resistors of the precharge circuit (20ohm / 10W). I am posting an image  of the electronic schematic with the part of the pre-charge circuit  circled in blue. Following this repair, the station was switched on once  without any problem. On the other hand the second time, the problem  reappeared, the station blew the electrical circuit breaker of the room  twice before starting normally. We reopened the machine and took  measures and it turns out that the two resistors are dead. Is it  possible to replace these resistors with resistors of greater value even  if this is not what was originally there? Or does this failure mean  that there is a faulty component upstream or downstream? If so, where to  look? Thank you all for your advice and advice!
