Master T – Master of AC and DC TIG welding

Master T – Master of AC and DC TIG welding

Master T is a premium TIG welding machine for professional AC DC TIG welding. It delivers exceptional weld quality, precision, and energy efficiency. With advanced features like MAX WeldClean and DeMagnetization mode, it boosts productivity while ensuring consistent results.

Precision from start to finish

A smooth arc ignition you can rely on allows greater control and precision. Weld Assist helps guide you to a faster set-up, even at lower current parameters. And lower noise levels help you maintain focus throughout your welds.

Powerful performance

Every Master T model has an increased power output, combined with features such as Double Pulse, MicroTack, and AutoCool, to give you a greater range of welding speed, control, and energy efficiency.

Productivity innovations

Every ACDC model includes unique modes: MAX WeldClean allows the Master T to function as an electrolytic cleaner, and DeMagnetization eliminating a remnant magnetic field of the parent object.

Master your TIG welding

The Master T TIG welding machine sets the benchmark for weld quality, usability, and energy efficiency in professional AC DC TIG welding. Built for welders who demand precision and companies who value efficiency, Master T combines advanced welding performance with durability and ergonomics to excel in any environment.

Available in power variants up to 500 A, Master T delivers a smoother arc ignition, reduced noise levels, and enhanced control, ensuring consistent, high-quality results from start to finish. Weld Assist technology speeds up setup, even at lower currents, helping you meet tight deadlines without compromising weld quality.

Every Master T ACDC model comes equipped with two industry-leading features as standard:

  • MAX WeldClean – transforms your Master T TIG welding machine into a powerful electrolytic cleaner, allowing you to make welds customer-ready without extra equipment.
  • DeMagnetization mode – eliminating material magnetism for improved arc stability and direction.

The Master T’s modular design lets you tailor your setup with alternative control panels, wireless remotes, and transport carts. Its robust, lightweight construction, crafted from impact-resistant injection-molded plastic, is designed to withstand the toughest welding conditions while remaining easy to handle. Paired with our Flexlite TX TIG torches, you get unmatched comfort and arc control for long shifts.

For welders, this means a reliable, easy-to-use machine that delivers top-tier results every time. It’s an investment in future-fit welding technology that improves productivity, reduces downtime, and supports sustainable, energy-efficient operations.

Master your craft with Master T — the professional’s choice for TIG welding.

Magnetism in welding: how to deal with magnetic blow

When welding ferritic steels, especially high-strength grades, magnetic blow can become a real challenge. This phenomenon occurs when magnetic fields interfere with the welding arc, causing instability, spatter, and sometimes making welding almost impossible.

How Rapid Welding and Kemppi Built a Partnership That Lasts

How Rapid Welding and Kemppi Built a Partnership That Lasts

Rapid Welding has worked with Kemppi since the company opened in 1990. Co-founder and Managing Director Roy Edwards highlighted the principles behind that 36-year partnership, from choosing the right welding solution and supporting equipment throughout its life to addressing the skills shortage and finding the right place for automation and laser welding.

Kemppi's advanced welding processes: TIG and stick welding (MMA)

Kemppi's advanced welding processes: TIG and stick welding (MMA)

In TIG welding, process development has mainly focused on modifying the current modes in different situations. In practice, this means variations of pulse and AC welding, as well as ignition or tack welding. In the case of pulse welding, the welding machine user has numerous choices, as the adjustment possibilities for these process variations are highly versatile.

Safety that keeps up with welders' challenges and changing risks

Safety that keeps up with welders' challenges and changing risks

Welding safety has become increasingly demanding. The hazards at the arc remain constant, but modern working conditions mean exposure can accumulate over longer shifts and in tighter indoor spaces. As a result, welding PPE needs to be treated as both protection for the welder and proof of compliance. At Kemppi, welding safety PPE is designed and validated in practice through clear requirements, welder-led feedback, and verified compliance with EU PPE Regulation 2016/425, CE marking processes, and relevant EN standards.
