OTC DAIHEN C70 High-Performance Air Plasma Cutting System
The OTC DAIHEN C70 (Power Source Model: MRCT-70) is a rugged, inverter-based air plasma cutting machine engineered for industrial metal fabrication and scrap dismantling. Operating at a rated output of 70 Amperes, it utilizes compressed air as both the plasma and shielding gas, cutting steel up to 4 times faster than traditional oxy-acetylene torches. The advanced inverter circuitry stabilizes the plasma arc, producing an ultra-narrow cutting kerf, clean dross-free edges, and minimal thermal distortion. Compatible with both ergonomic handheld curved torches (CT-70) and straight automated torches (CTP-75) for CNC cutting carriages, it is the versatile choice for steel construction and boiler fabrication.

🔧 Engineering & Operational Guide
- Air Quality & Moisture: Clean, dry compressed air is critical for plasma cutting. Ensure an industrial air filter, coalescing moisture separator, and oil lubricator remover are installed upstream; wet air destroys plasma electrodes and nozzles in minutes.
- Consumable Stand-off Distance: Maintain the recommended torch-to-workpiece stand-off distance (typically 3–5 mm) using a standoff guide or drag shield. Touching the copper nozzle directly to plate during high-amperage cutting will cause double-arcing and nozzle melt-off.
- Pierce Height & Technique: When piercing thick plates, tilt the handheld torch at a 15° angle initially to blow molten sparks away from the torch tip before standing upright to complete the cut.
