Pondering selling my Dayton hand held spot welder vs taking to Australia.
Assuming I have a transformer to knock 220 down to 110 that will handle
the current, will 50Hz adversely affect performance? Is there anything
about that which would require uprating a transformer a bit?

Thanks,

First, they have 240 Volts and often a little higher.

Second, for 50 Hz you need to derate by 20% so if the welder will take
120 V / 60 cycles you need to run it on 100 V / 50 Hz otherwise you
will smoke the transformer. Been there, done that. Now if the duty
cycle on the welder is very low you might get away with 120 V OK.

So it comes down to availability of a step down and $$$$. See if you
can order a 50 cycle transformer with taps at 100/110/120.
