Tig Welder - EWM Tetrix 421 AC/DC activArc
All EWM Machines come with a three year parts and labour warranty.
Highlights
Maximum efficiency for all requirements with reproducible welding results and excellent quality thanks to the fully digital inverter welding technology - Unique AC functionality: Synchronous operation of 2 machines for two-sided, simultaneous welding, AC special for the easy joining of very different thickness aluminium panels, e.g. 1 mm to 10 mm
- EWM activArc – the powerful TIG arc - faster, better and simpler welding across the entire power range
- Self-explanatory, intuitive operating concepts for everyone - either the standard setting, job mode or synergic one-dial operation so that you can concentrate fully on your welding task!
- Maximum mobility: Easily movable thanks to large wheels, fits through standard doors, easy loading and unloading thanks to the even wheel gauge, transportable by crane and fork lift
- Intelligent casing design with optimised air guidance for longer duty cycle and ventilation control for less contamination in the machine.
- Powerful cooling system for the torch, with centrifugal pump, cooler with large surface area and an extra-large tank (12 litres)
- COMFORT, SYNERGIC: Ideal for robot, industrial bus and mechanised applications and documentation via optional interfaces
Main Areas of Use
- TIG AC welding: Aluminium and aluminium alloys
- TIG DC welding (minus pole): Unalloyed, low-alloy and high-alloy steels, nickel-based alloys, copper and special metals
- MMA welding (direct current) with rutile and basic coated electrodes: Unalloyed and low- and highalloy steels, nickel-based and copper alloys
- Production and repair work, metal construction, food and chemicals industries, pipeline, closed container and equipment construction, vehicle, machine, plant and tool construction, and more
