DC Basic
Pi 350/500
Control panel for simple TIG DC (direct current) welding with high-frequency ignition.
The panel is for Pi 350 and 500 where heavy use and welding thick plates without pulse is most common. For mild and stainless steel.
DC HP
Pi 250-500
Control panel for TIG DC with high-frequency ignition and pulse. The panel is for Pi 250-500 where pulse welding is preferred for sheet metal, and where finish is important.
All pulse functions are controlled using the middle column of buttons. Each function has its own button so it is easy to switch on/off or adjust parameters.
AC/DC
Pi 250-500
Control panel for TIG AC (alternating current) and DC with high-frequency ignition and pulse. The panel is for Pi 250-500 where pulse is preferred, and if you ever need to weld in aluminium.
All AC functions are controlled using the top column of buttons. On all panels, the top left shows the welding cycle with associated elements that are open for adjustments, e.g. pre gas flow, start amp, slope up/down and post gas flow.

TIG-A-Tack - fixation
TIG-A-Tack is a semi-automatic process that makes extremely small and precise fixations in austenitic stainless steel. For most operations, it is possible to do without root protection gas. The ultra-small fixation points are invisible in the finished weld.
The low heat input and a minimum of weld penetration lowers the risk of weakened corrosion resistance and deformation of the welded material compared to ordinary tacks. Use TIG-A-Tack for quick tack welding of tubes, pipes or plates in sheet metal.
How to set-up TIG-A-TACK
Setting the parameters for TIG-A-Tack is easy: activate tack funktion, adjust time in 0.0x seconds and set your amps. Use TIG-A-Tack for quick tack welding of tubes, pipes or plates of austenitic stainless steel.
Intelligent Gas Control (IGC®)
With IGC, the welding machine always uses the right amount of gas for every weld. When you always have the optimum gas protection, there will be no holes, pores or impure welds.
Reduce the risk of failures created by insufficient gas flow or gas turbulence. Improve the weld quality and reduce your gas bill at the same time. IGC® is an optional feature.
Creating hygienic joints
for demanding industries
The pursuit of accuracy
Welders' pursuit of accuracy in their welds in the Pharma, Food, Beverage, and Petrochemical industries is no joke. Hygienic joints with reduced risk of bacterial growth is the ultimate goal. Quality control is performed frequently and with an eye to every detail. The strict legal requirements in these industries put pressure on welders' craftsmanship and their equipment.
The essential tool for high-quality welds
The TIG welding process is known for precision and cleanliness. This is important when manufacturing equipment for processing food, beverages, or medical supplies, as it helps maintain the integrity of the steel used. For every weld, there is a risk of weakening the corrosion resistance, so welders are concerned with clean surfaces to avoid contamination. Pi welding machines are designed to minimize these risks, which is crucial where even minimal contamination can have serious consequences.
Meet the strict quality requirements
Pi can work in tight spaces and at various angles, making them a versatile choice. They fully live up to industry standards by providing welders with essential functions to produce a final product
that satisfies strict quality requirements. The Pi machines also offer a high level of user-friendliness. They are easy to set up and use, which allows welders to focus on their work, without having to worry about complicated settings or technical difficulties.
Safe and efficient production process
By investing in Pi equipment, you can ensure a safe and efficient production process. With their ability to offer precision, cleanliness, and versatility, Pi welding machines are an essential tool for any welder working in the Food, Pharma, and Petrochemical industries.
