Hi, I'm a new guy here. Just bought a Dynasty 280 dx tig runner. As I read it, the 60/80 Amp fuse rating (230 volt single phase) is the "MAXIMUM" size fuse you would want to use. It looks like a standard 60 Amp circuit breaker would be fine as long as the wiring is the correct size. I think the "maximum" spec is saying to not go any higher or a short circuit will melt the wiring?
At 230 Volts Single Phase the machine should only pull 52.8 Amps?
From page 15, the 52.8 Amps would be 280 Amps when stick welding. 280 Amps Tig would be 38.6 Amp, but I don't know it that includes the cooler power? Right now I am using a standard 50-Amp breaker and a 6-50 NEMA plug with 8-awg wiring, but when I measured my voltage it was 248 VAC (not too far from the line transformer.)
I just got the Machine and so far I have only ran it at maximum of 150-Amp Tig welding. I welded for a few hours the other day, but nothing using alot of current and never tripped the circuit breaker.
For comparison, from the manual, the 100% duty cycle ratings of 190 amp Tig and 145 stick the input current is only around 24.5 (26.4 stick) Amps.
FWIW, I got my Dynasty from IOC it was about $100 less than CyberWeld:
