MAGNUM TIG THF 354 AC/DC PULS inverter welder with cooler and chassis TIG 18/4m chuck

The THF354 AC/DC PULS from MAGNUM is a professional inverter welder designed for TIG HF (non-contact arc ignition) welding with AC and DC welding. The THF 354 provides excellent performance in welding aluminum and its alloys, unalloyed steel, low-alloy steel, high-alloy steel, titanium and other weldable metals and alloys. The device can also be used for MMA welding with fusible covered electrodes.

The THF 354 welder is powered by a three-phase 400V mains, and has a high 100% duty cycle at 280 A, which allows it to be used in various industrial segments. The device has an intuitive, easy-to-use control panel, which allows quick and precise selection of individual welding parameters. The control panel is equipped with a digital – graphic and numeric display showing the values of individual parameters, the adjustment of which is carried out with a single knob.

The welder is characterized by a wide range of applications, dedicated to all kinds of welding work in factories, industrial plants, locksmith shops, repair shops, etc.

The digital function panel allows precise control of all major welding parameters for TIG AC/DC methods:

– TIG process flow chart,
– Waveform selection for TIG AC welding – sine wave, rectangular wave, trapezoidal wave, triangular wave
– AC balance,
– AC current frequency,
– Gas discharge before welding,
– Start current,
– Current rise time,
– Welding current,
– Current fall time,
– End (quench) current,
– Gas discharge after welding
– TIG PULS: Peak current, base current, pulse frequency, pulse width
– 2T/4T operation mode
– Memory – save your own settings

and the most important parameters for DC MMA methods:

– Welding current intensity,
– Arc Force – stabilizes the welding arc and eliminates short circuits, facilitated welding in forced positions.

The current source is built on the basis of IGBT (Insulated Gate Bipolar Transistor) transistors, which provide a minimum of electromagnetic interference, low power loss in the basic circuits, enabling increased efficiency and reliability of the current source. Very high efficiency, which translates directly into lower power consumption, and high switching frequency, provide instant adjustment of current to changes in parameters during welding.
