PONTIG 300 DC MOST is a modern inverter welding rectifier for TIG DC welding of steel, stainless steel, or shielded electrode (MMA). Efficient industrial equipment powered by 3x400 V current.
Main applications:
- Food industry and welding of stainless steel installations.
- Chemical industry and pipelines.
- Craftwork, making light objects from steel, stainless steel and copper alloys.
- Yacht building, welding of rigging, etc.
Features:
- High TIG DC welding current (300 A) at low source weight (19.4 kg).
- Modern and legible control panel.
- Modular design: optional cooler connected to the power source with a single cable, to be placed on a weldin tractor.
- High ergonomics of work, both for “gas” and “water” versions.
- IP23 enclosure protection rating – possibility of operation outdoors, e.g. repairs, on construction sites, etc.
- Compliance with the Ecodesign Directive requirements – high efficiency (85%) and low idle power consumption (20 W).
- Welding parameters memory.
- Possibility to connect remote control or work with TIG torches with Up/Down control in the handle.
- TIG arc ignition either by HF or by scratching the tip of the tungsten electrode.
