Hello, I have an xmt350. The last 2 times that I have air arced with it at 325 amps, then went to weld once was with stick 3/32 7018 at 103amps and once was with an LN25 .045 outershield wire at 25.4 volts. With the wire it was melting the wire to the tip almost instantly and with the stick it was extremely hot. I almost went through a backhoe bucket in seconds. I looked at the settings on the machine and the voltage side would read 4. I shut down the machine and used a different machine to finish my task. A few days later I stick welded with the same machine and it worked fine. Then several days later I air arced again then went to weld and it was messed up again. Any help would be appreciated.
