Not as far as I can tell. The owner's manual doesn't indicate anything about
purging per se, but here's how it describes setting the gas flow rate:
Flow Adjust
Flow rate should be set when gas is
flowing through welding power
source and welding gun. Open
feedhead pressure assembly so
that wire will not feed. Press gun
trigger to start gas flow.
I could be wrong, but I assume that a purge valve could be used here, if the
140 had one.
