    MASTER YOUR TIG WELDING

    The Master T TIG welding machine sets the benchmark for weld quality, usability, and energy efficiency in professional DC and 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.

    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.

    Product Details

    Available in power variants up to 400 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.

    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-moulded plastic, is designed to withstand the toughest welding conditions while remaining easy to handle. Paired with Kemppi's 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.

    Kemppi Master T 355A AC/DC Air Cooled Machine Parts FAQs

    Remote controls, control panels, transport units and weld-cleaning kits for a high-output AC/DC TIG power source used with an air-cooled torch, and how to choose the right ones.

    What kinds of parts and add-ons go with a high-output AC/DC TIG power source?icon-minus-redicon-plus-red

    Common groups are remote controls (foot pedals and hand controls), control panels, transport units such as carts and trolleys with a cylinder carrier, and weld-cleaning kits for stainless steel.

    These are normally made for a particular family of machines, so check the data plate and the manual to confirm that an item suits your power source before ordering. Also check whether it is meant for your torch type, as some accessories only fit certain torch heads. If you are unsure, our team can help you choose.

    When is a foot pedal better than a hand remote on a TIG machine?icon-minus-redicon-plus-red

    A foot pedal gives smooth control at a bench, where you can sit and rest your foot on it. Pressing further raises the current up to the maximum set on the machine, which helps on aluminium and on parts that change thickness.

    A hand or torch remote is more convenient when you are moving around the work, working in confined spaces or out of position, but adjusting a dial while welding can nudge the torch. Many welders keep both. Practise with each on scrap so that you know which suits your work before relying on it for a finished joint.

    Why does an air-cooled torch get hot, and how do I stay within its limits?icon-minus-redicon-plus-red

    An air-cooled torch relies on the surrounding air and the shielding gas to carry heat away, so heat builds up with the current and the torch can become uncomfortable or overheat on long welds at high output. Its rating is given as a duty cycle: the percentage of a 10-minute period it can run at a stated current without overloading.

    Running above the rating makes the handle and cable heat up faster, which can mean stopping to let it cool. Stay within the maker's ratings, rest the torch between welds, and consider a water-cooled torch if you regularly weld at high current for long periods.

    What does an electrochemical weld-cleaning kit do?icon-minus-redicon-plus-red

    It removes the heat tint (coloured oxide) left around stainless steel TIG welds. A pad or brush carries an electrolyte over the weld while an electrical current passes through it. The coloured areas show that the protective chromium oxide layer is not intact, and the process restores it by cleaning and passivating in one step.

    It is used as an alternative to chemical pickling or abrasive cleaning. It is intended for stainless steel, so do not assume it suits other metals unless the maker says so. Always follow the maker's instructions for the electrolyte and the kit.
