Dear Experts, Would really appreciate your help guys. I own a Murex Tradesarc 131i which has currently stopped welding with no welding spark, fan and leds are still ok. Found board 481 847-00IC K-SIDA with faulty 0.033uf capacitor (which is next to the part number printed on the circuit board) and a burnt wire wound resistor which is next to a 2u2 capacitor. The wire wound resistor is so burnt that cant read the resistance value. I have changed the capacitor and the burnt wire wound resistor with a 25K ohms and now I have a spark but very very weak and only one first spark after second ( and following) contact there is no spark. Would really appreciate your help on this, about the resistance value and other suggestions to fix this issue perhaps indicating voltage levels of some test point.
