3-in-1 versatility

• AC/DC TIG welding: in alternating current (AC) and direct current (DC), suitable for steel, stainless steel, aluminum, copper, titanium and many other metals.
  
• MMA welding (coated electrode) up to 200 A.
  
• Plasma cutting (CUT) up to 50 A, allowing all conductive metals to be cut with precision.
  

Cutting performance

• Structural steel (ST37): up to 12 mm.
  
• Stainless steel (V2A / V4A): up to 8 mm.
  
• Aluminum: up to 5 mm.
  
• Compressed air-assisted plasma jet for fast, clean and effortless cutting.
  

Advanced pulse function – TIG PULS

• Prevention of material burning and reduction of thermal deformation.
  
• Particularly suitable for welding thin sheets requiring low heat input.
  
• Adjustable parameters: pulse current, pulse width, pulse frequency, long pulse and short pulse.
  

Modern IGBT technology

• Latest generation IGBT transistors for high performance and maximum stability.
  
• Superiority over old MOSFET technology and conventional transformers.
  
• Integrated HF ignition: contactless ignition, more stable arc, improved welding results.
  
• Actual power: 200 A with 230 V single-phase power supply.
  

Compact and ergonomic design

• Lightweight: only 13 kg.
  
• Reduced dimensions: 455 × 220 × 370 mm.
  
• Easy transport and use thanks to its optimized construction.
  

Cooling and safety

• Intelligent, high-performance cooling system.
  
• Built-in overheat protection for optimum safety.
  
• Extended use possible without loss of power.

Advanced TIG welding control: 2T / 4T

• 2T mode : the arc remains active as long as the torch button is held down, ideal for short, precise welds.
  
• 4T mode : The arc ignites after pressing and releasing the button, and extinguishes after a second press. Allows for additional adjustments, such as reducing the current during welding.
  

Current regulation

• Current increase/reduction : prevents the formation of shrinkage points (final craters) at the end of the weld, ensuring clean and professional welds.
  

Plasma cutting (CUT)

• HF contact ignition : precise ignition from the first pass, simplifying cutting of all conductive metals.
  
• Adjustable cutting current : from 15 to 50 A depending on the material and thickness.
  
• Automatic air tracking : After cutting, air continues to circulate to cool the torch, protecting the nozzle and electrode, and extending the life of the unit.

Gas control (TIG)

• Gas advance and delay : protect the tungsten electrode and the welding seam from oxidation. The gas flow times before and after ignition are individually adjustable.
  

AC Balance

• Variable adjustment allowing you to choose between oxide layer rupture (-) and deeper penetration (+) , to optimize welding according to the type of metal and alloy.
  

Remote adjustment

• Via the torch : integrated rotary regulator to adjust the welding current in real time.
  
• Via the foot pedal (optional) : current control even during welding, offering flexibility and precision.
  

Welding current / pulsed

• Allows you to set two different intensities between which the current automatically alternates for optimal welding.
  
• Pulse width : duration of pulse current intensity before returning to normal current.
  
• Pulse frequency : frequency of alternation between the two current values.
  
• Long Pulse : wider weld, increased heat input and deep penetration.
  
• Short Pulse : better control of the weld pool and reduced risk of perforation.
  

Additional functions

• Foot pedal : Remote stepless current control (not included). The maximum current is set on the device; the foot pedal adjusts the starting current and maximum current based on the pressure applied. The pulse function is not available in foot pedal mode.
  
• Hotstart : Automatic voltage increase at startup for optimal priming.
  
• Anti-Stick : Automatic current reduction when the electrode sticks, making it easier to remove.
  

Integrated welding processes

• TIG (Tungsten Inert Gas) : welding under inert gas (argon 4.6, 99.996%), for a precise and clean weld bead.
  
• MMA / ARC (coated electrode) : universal gasless process, using an electric arc to melt the electrode and form the bead.
  

Important note

• The device is not suitable for residential areas supplied by a public low-voltage network, due to possible electromagnetic interference by conduction or radiation.
