Magnum THF 335PULS AC/DC TIG inverter welder
The Magnum THF 335PULS AC/DC is a professional, digitally controlled inverter power source for TIG and MMA welding. It was designed for demanding users who expect full control over the process and the best weld quality, above all on aluminium and stainless steel. Advanced functions such as double pulse TIG and full adjustment of the AC wave characteristic make this model an alternative to far more expensive premium machines, in line with the Magnum approach of delivering maximum value at a competitive price.
Key features
Professional TIG AC/DC welding (aluminium, mild steel, stainless steel)
Advanced double pulse TIG function (Dual Pulse) for a weld face with the look of the TIG process
Full control of the arc parameters: AC balance, AC frequency, wave shape
Reliable HF arc striking (without contact)
Efficient MMA welding mode with Arc Force adjustment and a Hot Start function
Modern IGBT inverter technology for high output and stable operation
Digital control panel with program memory for repeatable settings
Technical details
Technology in detail
At the heart of the THF 335PULS AC/DC sits inverter technology built on IGBT transistors. It gives not only high energy efficiency and portability, but above all a stable arc and an immediate response to parameter changes. The key technology is double pulse TIG welding (Dual Pulse), which modulates the current and the pulse frequency and lets you obtain a clean, stacked-dime weld face while limiting the heat put into the material. In AC mode, full adjustment of balance and frequency gives precise control over penetration and cleaning when welding aluminium. On top of that, the MMA mode has an adjustable Arc Force function that steadies the arc and keeps it from going out, which makes work with difficult electrodes easier.
Recommended applications
- Professional metalwork and welding shops
- Production and repair of aluminium structures (frames, tanks)
- Welding stainless steel for the food industry and for decorative work (railings, furniture)
- Automotive industry and motorsport (exhaust systems, intercoolers)
- Work that calls for the highest precision and weld appearance
Control panel
The machine has an advanced and clearly laid out control panel with a digital display that gives full control over every stage of the TIG process. You can set parameters such as pre-gas and post-gas flow, start current, up-slope and down-slope time, welding current and base current, along with the advanced pulse settings and the AC wave characteristic. Intuitive knobs and buttons together with the channel memory let you store and quickly recall proven settings, which speeds up repeatable jobs considerably.
