spectrum 625 X-TREME tripping breaker on 120volts

[Iron Designs]

as soon as i start cutting it trips the breaker? I've checked my settings and I'm running on a 20AMP receptacle and breaker? I may have skipped something in the manual...... any suggestions welcome thanks' dallas desantis

Make sure it's a dedicated 20amp circuit.

Unplug anything else on that circuit.

If it is try turning it down below max level on 120V

Just a longshot; have you cut on this particular circuit previously?

It could be wired as an arc fault interrupter circuit which will not run a plasma cutter

I'd guess it would trip as there is NOT ANY 120 capability on a 625

The spec sheet says it automatically reduces output to 27 amps for 120vac operation. The thread title states it is an xtreme model.

Out of curiosity, I looked at the Spectrum 625 Xtreme spec sheet on this Miller website, and here is what shows for INPUT POWER


:4-1. Specifications

230 1 PH


No 120v as Cruizer has already stated.

P.S.
There was also a warning about incorrect input voltage damaging the machine. Soooo.

from product page

Spectrum® 625 X-TREME™ with XT40 Torch

Big cutting power in a small package - the industry's most portable and powerful 40-amp plasma cutter offers 5/8 in. mild steel cutting. The unit offers easy connection to 120V or 240V input with Auto-Line technology and MVP Adapters.

confusing no?

Apparently some models of the 625 run on 120, and some models don't. All depends on the serial#. Personally If the machine is autoline, then I'd trust it to work properly. So if you have a newer machine, lower the nozzle sizes. Maybe having a fault there.

Are you connecting direct to the receptacle or using an extension cord?
