TIG 250 MMA Inverter Welder is an arc welder with inverter technology that converts alternating current into direct current to deliver precise and efficient welding. This unit uses a constant-current transistor to convert alternating current into a frequency above 50 kHz, allowing for a compact and lightweight transformer, making it easier to transport and use in different environments.
The high operating frequency significantly reduces the size and weight of the transformer compared with traditional welders. For example, the transformer in a 160A inverter welder weighs only 0,25 kg compared with 18 kg in a conventional welder, demonstrating the technological advantage of this unit.
Main features:
- Inverter arc welder fitted with a turbo fan for extended work without interruptions.
- Safety system that stops the machine in the event of overheating, ensuring durability and protection.
- Compatible with electrodes made from different materials, allowing fast and professional welding.
- Digital display for precise control of welding parameters.
- Compact design with dimensions of 420×220×380 mm and net weight of 12 kg.
- IP21 insulation class, ensuring resistance in demanding work environments.
- Compatible with generator sets, ideal for use in places without direct power supply.
