I have a Clas Ohlson MIG 130 welder machine from the early 1990:s that is most likely a OEM machine very similar or identical to a Telwin MIG from what I have heard. The current selector, which is a 5 positions and 3 sections rotary switch marked Bremas A 1200 SCH 7074, is broken and I want to find some documentation on it to replace the switch. Anyone having a Telwin Welder with the same caracteristics that can send me information on the switch charactersitics? I have included pictures of the welder and the switch markings.
