Full-digital inverter low-spatter welding machine
PRODUCTS
CO₂/MAG/MIG GMAW welders
Full-digital inverter control, from low-spatter to pulse and double-pulse models
Gas metal arc welding is one of the most productive semi-automatic processes in steel structures, automotive parts and construction machinery. The DAIHEN (OTC) CO₂/MAG/MIG range is built on full-digital inverter control and extends from low-spatter models to DC pulse and double-pulse machines, plus high-efficiency MAG/CO₂ models.
Technical characteristics
- Full-digital inverter control: welding waveforms are generated digitally and settings are repeatable
- Low-spatter models (WE M350L, WE P400L / WE P500L) suit thin plate and visible work
- DC pulse and DC double-pulse models suit vertical, overhead and all-position welding
- New-generation intelligent inverter models (M350L / M500 / P400 / WB-P500 / W400) adjust parameters intelligently
- IGBT soft-switching inverter models (DM350 / DL350) balance output efficiency and reliability
- CPVE / CPVF / CPVS series address heavy-duty and long continuous operation
