In fact, I bought a new plasma cutter (Huayuan LGK 120 IGBT).The machine is also Chinese but much better than Stamos 85a plasma cutter.
With the machine I bought a 100A HD plasma torch (link: https://www.aliexpress.com/item/Hot-...66225.html?spm= a2g0s.8937460.0.0.755b2e0epJLQ9U).
Consumable parts are much better quality and longer lasting.
