• Robust, small and portable
  • Output up to 350 A
  • Welds rutile, basic and cellulose electrodes up to 7 mm 

The TransPocket 3500 is a fully digitally controlled manual electrode power source with resonant intelligence. The ideal characteristic ensures the arc is always stable, even for example at mains voltages of up to 100 metres, or with fluctuating mains voltages (340 to 506 V) and during generator operation.

The TransPocket 3500 is guaranteed to weld all electrode types up to 5 mm – including the vertical-down welding of cellulose electrodes. It is extremely robust and yet small, light and portable.

Overview

Overview

  • Anti-stick function 
    Prevents the electrode from sticking following a short circuit
  • Cellulose-compatible 
    Vertical-down compatible welding for cellulose electrodes
  • Generator-compatible 
    for mobile use, including construction sites
  • Hot start 
    Makes ignition of cellulose and rutile electrodes easier.
  • Single-phase operation (up to 140A) 
    A 230 V connection is sufficient for the power supply
  • Soft start 
    For a stable arc when using basic electrodes that take little welding current to ignite
  • Spatter-free ignition 
    for a jolt-free and spatter-free welding start, with less time spent on rework

Resonant Intelligence
Just imagine your’re driving down a wide, more-or-less straight highway. Every so often, there is a gentle bend in the road, or a slight gradient up or down. And then imagine doing this with cruise-control. You’ve set the ideal speed, and the system automatically increases or decreases the engine power to keep the car moving along at exactly this speed – makung your journey much more pleasant and smooth. Welding with resonant intelligence is just like this. It defines the ideal characteristic, and this remains ideal – no matter what happens to the conditions in the background. The Fronius “resonance concept” was developed for rod-electrode welding.
