Key Features
- Built-in 1500 W high-pressure compressor: no external compressed air required
- Cutting and manual arc welding combined in one mobile unit
- Switchable between internal air source and external supply
- Four-stage low-speed motor drive for longer piston life and quieter operation
- Anti-vibration compressor mounts reducing shock, noise and component loosening
- High-precision pressure-regulating filter with fine filtration and stable regulation
- Two 1000 µF / 400 V filter capacitors: strong supply-fluctuation immunity, generator compatible
- Over-temperature, compressor phase-loss and over-voltage / under-voltage protection
Typical Applications
- Pipeline, steel structure and power-plant installation sites
- Outdoor equipment repair and emergency maintenance
- Metal demolition, rescue and recycling dismantling
- Mobile jobs without a compressed-air supply
- Remote construction and infrastructure maintenance
Selection & Setup Notes
The 125AM raises output current over the 105AM for duties that need mobility plus slightly thicker plate. It is positioned as a mobile station: for high-intensity continuous production at a fixed station, a conventional source on external air is still preferable — see inverter air plasma cutters.
Standards & Further Reading
External reference: ISO 9013 — Thermal cutting classification — ISO 9013 defines the quality classes for thermal cut surfaces (perpendicularity, bevel, dross).
