I have a Syncrowave 350LX with either more miles than the sun, or very few. I held down the current and output buttons and read the display. It had 18.7 766 for the time and 03.6 714 for the cycles. The manual doesn't tell me anything about what the decimal means. No idea if that's 18.7 hour or 18.7 thousand. The machine is in great shape and everything works just fine. Turns out I really want a mig machine, so I'm selling this one and the question of hours came up.
