Hello, I'm a newbie at welding and I bought the Telwin Force 195. I had no experience at all and it seemed too easy to weld and start an arc with this machine. I haven't used it a lot but it started to be much harder to start an arc with a new electrode. When an electrode has been used and the flux extends much longer from the metal part it's working fine. With new electrodes it always stucks and I have to try 5-10 times to start the arc. I have tried more than 50 electrodes and it happens every time. My concern is that I could always start an arc with new electrodes when the machine was new. I measured the OCV and the multimeter reads about 20V. I know it's low but I'm not sure if that measurement is an indication of a problem and what problem it is. Could anyone with a similar machine measure the OCV? What could be the problem? Should I replace the IGBT?
