This tube is better than the one that came with my machine. I had to dial back my settings because it was burning through the piece instead of engraving. Installation was fairly easy. I put a piece of tape where my old tube's output was and put the new tube at the same spot. Solder would not stick to the electrodes, so I wrapped the wire and coated the wire with solder, then I covered that with electrical tape. I didn't have to make any adjustments at all. Everything worked perfectly. If I had known how good this tube was going to be, I would have bought two.
