If you use High Frequency for a start mode it will put a coating on the tungsten and after a while it will not start Just drag it on the work and it will be good for more starts Or sharpen the tungsten. I preferred a long point on mine but some people dont like that. The long point gave me more pinpoint heat needed when doing x-ray welds on pipe. It was also easier to weld with it if you goobered it up Lol
