  • Syncrowave 250 delay high-frequency starting

    I recently purchased a 1995 syncrowave . On ac hf alum continuous hf starting it has a delay like 3-5 seconds to initialize arc. What causes this? Our newer digital syncrowave at work does this too

    Is it preflowing the shielding gas? Have you looked the troubleshooting section of the manual?

        Isn't that arc delay to allow for the pre-flow?

          It could be something else but Mac might have it. This happened to me once when the pre flow knob got turned by mistake. Took a while to figure it out. Check that the preflow knob is at zero and it should light right up.
