Just got off the phone with twch support and was told the PowerTig 250ex only goes down to 20amps in a/c and that something is wrong with my welder. He said when i flip the rocker to go from dc to ac and with the amperage knob turned all the way down, the amp display should switch from around 6 amps to 20amps because the 250Ex doesn't go lower than 20amps in A/C.

Is this true? The advertised output rating is 5 amps minimum in both ac and dc. I specifically purchased the Powertig250ex rather than other models becuase of the lower amperage ability in a/c.

Can someone from Everlast Tech Support or customer service please chime in here.
