I have this cutter and when I bought it many years ago it didnt work so I put it away . Now I want to try to get it to work . This cutter is from 1991 and was very expensive at that time. Its 150 amp and can cut 35 mm . After what I can see this is almost the same cutter as Cebora Fire 150. I can turn it on , air correct , pilot arc working but when I try to start Im only get a small spark between nozzle and workpiece . Its one burned resistor on PCB board marked R3 and i cant see how many ohm this is. I have schematics on Elettro and Cebora but not on the PCB . Is it anyone that have this/work on them or have servicemanual on this machines.
