  • Cuts 1/2 in steel cleanly on 240 V and runs on 120 V with the included adapter
  • Among the cheapest 55 A pilot arc cutters
Cons
  • High-frequency start can upset nearby computers and rules out CNC tables
  • Needs at least 72.5 psi at the inlet, more than small pancake compressors hold
  • Two-year warranty and no duty cycle temperature given
