Lower consumable costs

Spectrum 625 portable air-plasma-arc cutters' electronic pilotarccontrollers boost pilot current only when needed for strong arc transfers, extending tip lives, and lowering consumable costs. They work well with engine drives with a least 8 kW of power because their power-factor-correction (PFC) circuitry reportedly uses incoming power with higher efficiency than competitive units. As a result, they use about 30% less.
