Magnum THF 238P AC/DC PRO-X inverter welder
The Magnum THF 238P AC/DC PRO-X is a professional TIG machine built for the most demanding users. As the flagship model in the Magnum line, it combines 200A of output with the advanced arc control functions needed for welding all metals, including aluminium and its alloys. With IGBT inverter technology and full AC/DC parameter control, this welder suits production plants, workshops and professionals who value precision and reliability at a sensible price.
Key features
Welding in all methods: TIG AC, TIG DC and MMA with a coated electrode.
Contactless HF arc striking for a clean start of the weld.
Full control over aluminium welding thanks to AC Balance and AC Wave Shape adjustment.
Advanced TIG Pulse function for precise control of heat input and bead appearance.
High duty cycle of 60% at the maximum current of 200A.
MMA support functions: Arc Force and Hot Start.
Digital control panel with a display for precise parameter setting.
Technical details
Technology analysis
At the heart of the THF 238P PRO-X sits advanced IGBT inverter technology, which gives a stable arc and high energy efficiency. The functions dedicated to the TIG process are the ones that matter to professionals. AC Balance adjustment lets you set the ratio of cleaning to penetration when welding aluminium, which gives a clean and strong weld. A choice of AC Wave Shape (square, sine) hands the welder full control over the arc characteristic. On top of that, the fully adjustable TIG Pulse minimises the heat affected zone, which is decisive when working with thin materials and stainless steel.
Recommended applications
- Professional welding of aluminium and steel structures.
- Manufacturing and service industry.
- Automotive and reconditioning workshops.
- Welding of stainless steel pipelines and tanks.
- Advanced assembly and repair work in workshop conditions.
Control panel
The control panel was designed for professionals who need full control. The central digital display shows every setting clearly. Intuitive knobs and buttons give quick access and precise adjustment of the key parameters: welding current, AC balance, pulse frequency, current down slope and post-weld gas flow. The logical layout of the functions lets you match the arc characteristic to the task at hand, from simple MMA work to complex operations on aluminium.
