Kemppi TIG Welders: A Buying Guide
Kemppi is a Finnish manufacturer with over 70 years of expertise in arc welding technology. Their TIG welding machine sets combine advanced welding performance with durability and precision, built for consistent arc stability and weld quality across industrial fabrication, maintenance, and repair operations.
At TEC Products, we stock both the Minarc T and MasterTig ranges, covering everything from portable site work to professional workshop fabrication, ensuring you get a future fit welding technology solution that supports sustainable and energy-efficient operations.
Choosing the Right Kemppi TIG Welder
Minarc T vs MasterTig: Which Range?
The Kemppi Minarc T series is the portable option, designed for light industrial manufacturing, installation, and on-site repair work. Compact and lightweight construction makes the Minarc T 223 ideal for engineers who demand precision and need to move between jobs without compromising weld quality.
The Kemppi MasterTig series is the professional-grade range, offering higher amperage power variants, advanced pulse settings, and both air cooled and water cooled configurations. The Master T ACDC model combines advanced welding performance with enhanced control and smoother arc ignition, making it the professional's choice for the toughest welding conditions. Its modular design lets you customise your setup with alternative control panels, wireless remotes, transport carts, and extra equipment to meet tight deadlines and reduce downtime.
AC/DC vs DC Only
All Kemppi TIG welders in our range are AC/DC models, enabling you to weld both ferrous metals (mild steel, stainless steel) on DC and non-ferrous metals (aluminium, magnesium) on AC. The demagnetisation mode neutralises material magnetism in the workpiece, preventing arc blow and improving arc stability.
Air Cooled vs Water Cooled
Air cooled packages are simpler, lighter, and suit intermittent welding or lower amperage work. The MasterTig 235 Air Cooled package is a popular choice for general fabrication, combining durability with energy efficiency and reduced noise levels.
Water cooled packages handle sustained high-amperage welding without overheating, making them essential for production environments and long shifts. The MasterTig 235 and MasterTig 535 are both available with water cooling, supporting sustainable and energy-efficient operations.

Frequently Asked Questions
Is Kemppi a good TIG welder brand?
Kemppi is a reliable Finnish manufacturer, with a global reputation for arc welding innovation. Their TIG welders are equipped with industry-leading features that improve productivity and reduce downtime. Users appreciate the easy-to-use machine interfaces, lightweight construction, and weld assist technology speeds setup. The Master T series, in particular, combines advanced welding performance with durability and energy efficiency.
What is the difference between the Kemppi Minarc T and MasterTig?
The Minarc T is Kemppi's portable TIG welder range, designed for site work and light industrial applications, with compact and rugged equipment ideal for long shifts. The MasterTig is the professional range with higher amperage capacity (up to 535A), advanced pulse TIG settings, and water cooled options for sustained high-output welding. Both ranges offer AC/DC capability for welding aluminium.
Can Kemppi TIG welders weld aluminium?
Yes. All Kemppi TIG welders in our range are AC/DC models, which means they support AC TIG welding for aluminium and magnesium. This capability is essential for fabricators who demand precision and high-quality results.
What voltage do I need for a Kemppi TIG welder?
Most UK workshops use 230V single-phase supply, which suits the Minarc T 223 and MasterTig 235. If you work on construction sites with 110V supply, the Minarc T 223 offers dual 110/230V input. For heavy industrial environments with three-phase power, the MasterTig 535 runs on 415V.
Should I choose air cooled or water cooled?
Air cooled TIG packages are lighter, simpler, and cheaper to maintain. They suit intermittent welding and general fabrication. Water cooled packages are essential for sustained high-amperage welding in production environments, as they prevent the torch from overheating during extended use. If you weld for long periods at high amps, choose water cooled.
