Great working single latch plasma cutter. This absolutely works when the current is reduced in short bursts on thinner metal. The first time I tried this, however, was with increased amperage on a 1/4" slab. This caused the breaker to hit the cut for 5 or 6 seconds. After repeating this several times, I reduced the amperage Still throw in a breaker somewhere around 15. I immediately went to the hardware store and bought everything I needed to hook up 230v. works fine on 230v, 20 amps. Great little plasma cutter! Now onto part 2. My Plasma cutter arrived without a 115V-230V adapter.As you can see above I needed this adapter.I contacted the company directly and asked them if they could send me an adapter.They asked for my address and phone number.As they had this information i got a tracking number for the UPS Saver from china i thought it would take a few weeks my package was sent out on the 7th and arrived on the 9th wow !AMAZING !Revain must be sent by d learn from this seller. This seller likes great service and ships packages at lightning speed. I assume UPS in the States could use the lesson here as well. In any case, the plasma cutter is of excellent quality and the company that sells it is SUPREME. I bought the Assurion guarantee as this is not my first rodeo with a Chinese plasma cutter.
