PONTIG 315 AC/DC MOST is a modern inverter welding rectifier for TIG DC welding of steel or stainless steel, TIG AC welding of aluminum and its alloys, or MMA electrode welding. It is an efficient industrial device powered by 3x400 V current.
Main applications:
- Food industry and welding of stainless steel installations.
- Aluminum structures, advertising, scaffolding.
- Chemical industry and pipelines.
- Craftwork, making lightweight items from steel, stainless steel, and copper alloys.
- Yacht construction, welding of rigging, etc.
- Sufacing and regeneration of all metals.
Characteristics:
- High TIG DC welding current (315 A) with low source weight (25.5 kg).
- Modern and legible control panel.
- Modular design: optional water cooler powered and connected with a single cable to the power source, to be placed on a weldin tractor.
- High ergonomics of operation, both in “gas” and “water” versions.
- Compliance with EcoDesign directive requirements - high efficiency (85%) and low idle power consumption (30 W).
- TIG DC current with constant or pulsed waveform.
- Three versions of TIG AC wave (sinusoidal, rectangular, or triangular) depending on the aluminum application.
- Welding parameter memory.
- Possibility to connect a remote control or operate with TIG torches with handle control (Up/Down).
- TIG arc ignition both by HF and by scratching the tip of the tungsten electrode.
