    Default my Syncrowave 350LX has Trouble

    I have a Syncrowave 350LX Serial # KJ286672.
    Welder welds great when stick welding but when you break the arc and set the stinger down
    Within 10 to 20 seconds the breaker in the breaker box trips.
    Any ideas what may be going wrong with this machine?

    What is the breaker size and what amps are you welding at? AC or DC, rod size.....

    AS Andy said, it's likely that your breaker is too small and not handling the field surge after you break an arc

    What does your owners manual recommend for a minimum breaker size?

    125A?

    Don't just install a larger breaker using the existing wiring. The wiring needs to be sized according to the amp draw.

    I guess you answered your own question then as 50 amps is barely enough power to run a little thunderbolt welder, let alone a biggun 350lx unit.

    50 amps isn't going to cut it. That's like jump starting your car with a lamp cord.
    I'm actually surprised it didn't trip the breaker sometimes when just turning the machine on from the transformer in-rush.

    As stated by Sundown, that machine likes over a 100 amp breaker and upsize your primary wire if needed.

    Good luck.

    I'm surprised you even got the rod to light at all

    A 3/16" 7018 needs 200-275 amps to keep lit

    95 amps is good for a 3/32" 7018 or a 1/8" 6010/11
