The Kemppi MasterTig sets a new standard for professional TIG welding. With its advanced Double Pulse technology and intuitive Weld Assist interface, it delivers unmatched arc stability and precision for AC/DC TIG applications. It is the ultimate tool for fabricators working with aluminum, stainless steel, and specialized alloys who require absolute control and a flawless finish.

  • Precision AC/DC TIG: Perfect for everything from thin aluminum to heavy-wall stainless steel.
  • Weld Assist Setup: Automated parameter calculation for fast, error-free welding.
  • Double Pulse Advantage: Faster travel speeds with significantly less heat distortion.
  • Industrial Toughness: Robust, impact-resistant design with high-contrast digital display.

Description

The Kemppi MasterTig is an industry-leading TIG welding system designed for professional welders who demand ultimate precision, high-quality arc characteristics, and advanced digital control. Available in various power classes, it is engineered for both AC/DC TIG and MMA (Stick) welding. Whether you are welding exotic materials like titanium and magnesium or performing critical root passes on stainless steel pipes, the MasterTig provides the stability and control required for X-ray quality welds. Its modular design allows for air-cooled or water-cooled configurations, making it adaptable to any workshop or site environment.

Key Features:

  • Double Pulse Technology: Combines two separate pulse cycles to increase welding speed by up to \(30%\) and reduce heat input by \(20%\). This results in lower distortion and a superior aesthetic finish, often compared to the “stack of dimes” appearance.
  • Weld Assist Automation: An intuitive graphical interface where the welder selects the material, thickness, and joint type. The machine then automatically sets the optimal parameters, significantly reducing setup time for complex alloys.
  • MicroTig Capability: Specifically designed for low-amperage precision work. It allows for a stable arc at extremely low currents, making it ideal for thin-wall tubing and delicate repair work on sensors or electronics.
  • iGroove Feature: A patented technology for the MasterTig 535 model that monitors the arc current and maintains a consistent weld bead even when the torch-to-workpiece distance varies.
  • Optix High-Contrast Display: Features a large, impact-resistant color screen that is easy to read even in direct sunlight or through a welding helmet, providing real-time data on every weld parameter.
  • Wireless Foot Control Support: Compatible with Bluetooth-enabled foot pedals and on-torch remotes, eliminating cable clutter and improving safety in the workspace.

 

Technical Specifications:

  • Power Supply: Available in Single-Phase (\(230\text{V}\)) and Three-Phase (\(400\text{V}\)) models.
  • Current Output: Ranges from \(230\text{A}\) to \(500\text{A}\) (depending on the specific model).
  • Duty Cycle: High-performance rating (e.g., \(300\text{A}\) at \(40%\) for the 335 model).
  • Pulse Frequency: Adjustable up to \(10\text{kHz}\) for high-speed automated applications.
  • Weight: Lightweight, portable design starting from \(19.1\text{kg}\) (Power source only).
  • Protection Class: \(IP23S\) (Designed for indoor and outdoor industrial use).
