COURSE OF ACTION
The machine will not produce more
than 200 amps.
1. This may be normal operation. If
the output current exceeds 290
amps, an electronic protection
circuit will reduce the current to
less than 200 amps. The
machine will continue to produce
this low current until the
protection circuit is reset. Reset
occurs when the output load is
removed.
2. Check the input voltage and input
voltage reconnect procedures.

3. Check for loose or faulty welding
cables.
2. The control board may be faulty.
Replace.
