Migatronic Pi - TIG welding machines from portable to heavy duty
Migatronic Pi are user-friendly welding machines, which meet every need for TIG and MMA welding. High-performance inverter machines for precision welding in mild steel, stainless steel, aluminium and other high-alloy materials. There is a Migatronic Pi machine for any type of welding operation: repair, assembly, construction, industry and robot. Processes include TIG HP (high-frequency with pulse), TIG H (without pulse), TIG AC/DC and MMA welding with covered electrodes. 

Robust and reliable welding quality
All Pi machines are delivered with coated PCB’s and carry Eurocodes calibration certificate.

Migatronic’s Pi range covers the entire spectrum from portable on-location versions to dedicated special and heavy duty machines with up to 500 A for automatic/robot welding.

Migatronic’s Pi machines combine proven inverter technology with new control and communication options. These features optimise welding performance and make the most advanced functions child's play to use. 

Pi 350 MMA CELL - a new Migatronic feature
Pi 350 MMA CELL is designed specifically for tube/pipeline welding and vertical downwards welding positions using cellulose electrodes. This means considerably increased welding speed, increased melting performance, and higher efficiency. Pi 350 MMA CELL can be used with an asynchronous generator. 

CWF Multi ensures uniform quality and high welding speed

TIG welding non-stop
CWF Multi (Cold Wire Feeder) is a separate wire feed unit designed specifically for setups with automatic devices and for optimization of manual TIG welding. CWF Multi has automatic wire-feeding from reels – with or without pulse on the wire. The CWF Multi control panel allows the welder to switch between programs and features automatic wire-feeding synchronously with the machine’s pulse function (Pi 350-500). 

Automatic wire-feeding
For optimization of welding quality and speed, the TIG welding hoses can be fitted with special equipment for automatic wire feeding. All Pi machines can via CWF Multi feed the correct quantity of wire into the weld pool; with or without pulse on the wire. The result is a considerable increase of welding speed and there is no risk of non-uniform welds and undesirable contact with the tungsten electrode. 

Automated TIG Welding Solutions
The Pi can be customised to any welding situation - including automated devices and robots. The two largest TIG inverters, the Pi 350 and 500, are obvious power sources for automatic devices/robots and prepared for communication with a robot or automatic device in a setup with the CWF Multi. 

The operating comfort follows the operator
All Pi machines for automated welding processes can be equipped with an extra identical control panel at the robot cell where the robot operator gets the same functions and facilities for setting the welding parameters.

Interfaces for all types of robots
RCI2 (Robot Communication Interface) integrates the large Pi machines with most types of robots and controllers. RCI2 is also used for ”Retrofit” - upgrade to state-of-the-art technology of old types of robots. All RCI’s are supplied to order by Migatronic in the required configuration.
