Three-phase welders feature resonant
intelligence
Fronius has evolved its resonant intelligence system and employed it in two new three-phase welding systems - the TransPocket 2500 and 3500.
Previously available only on the single-phase TransPocket 1500 welding system, Fronius has evolved its resonant intelligence system and employed it in two new three-phase welding systems - the TransPocket 2500 and 3500 With conventional MMA welding machines, fluctuations in the mains voltage and mains cables of different lengths have a negative effect on the output power

Welding for a quieter life
More compact performance, lower noise level, more stable arc and easier operation than conventional welding devices are the features of the new TIG welding systems by TPS-Fronius.
Noncontact cleaning boosts welding torch life
The electromagnetic Robacta TC 1000/2000 welding torch cleaning system can improve both quality and economy.
The same applies to changes in the arc length.
Fluctuations in the current then lead to changes in the arc, and in turn to poor quality welding results.
Such undesirable side effects are not an issue with resonant intelligence, even with cable lengths up to 100m.
If there is a short circuit, the controller briefly raises the current.
If the electrode threatens to sink into the weld pool, the increased current prevents the weld pool from solidifying.
This practically prevents the rod electrode from "sticking".
With all TransPockets "just-in-time" control of the power source generates a gently burning arc.
The welder can therefore also process cellulose electrodes up to 5mm in diameter in vertical-down seam position.
This is barely possible with most conventional welding machines.
The prerequisite for resonant intelligence is the resonance inverter developed by Fronius.
It generates an interaction between welding transformer and capacitor.
In addition to the capacitors, the transformer also takes on the role of energy buffer.
Resonant here denotes a particular condition: the transformer and capacitors are matched in such a way that they reboot each other.
The cleverly devised combination of resonance and buffer function creates power reserves that are on hand if required by the arc.
The welding current range of the three-phase TransPocket 2500 reaches 250A and that of the TransPocket 3500 is 350A.
Extra functions such as softstart, hotstart and anti stick complete the positive weld properties and make for added convenience when working.
Equally worth mentioning is the extremely robust housing with integral handle.
The machines' low weights (12.5 and 18kg, respectively) means they are ideal for portable use.
