“I-Cold Pulse™

Normally pulsing is a “HOT” process. This has always caused problems of metal distortion (in particular thin material) and working speed. Achieving a fast process has been the manufacturer’s challenge of the last years. New processes have developed with many different names under the insignia SPEED.

What about the HEAT?
This is the real challenge that STEL has taken with the innovative i-Cold Pulse™. Reducing the thermal heat STEL have been able to increase the welding speed by 35%. The arc is more concentrated and intense granting a better penetration.is the intelligent control of the Short Arc process, capable of handling automatically all the variations in the welding process.

ST-Arc™
The result is a short, concentrated and stable arc at 100%, a colder welding, a significantly lower heat and less deformation, less welding spatters and reduction post treatments. ST-Arc™ is a standard feature of MIG / MAG Stel welders.

AUTO – COMPENSATION:
Automatically compensates for any variation in welding conditions caused either by irregularities of the workpiece or the movements of the operator’s hand. Ideal for awkward angles.
GAP BRIDGING:
Charateristics of the IRON-MIG Short-Arc welding process is perfect for root welding and the welding of thin material where gaps need to be bridged, with little or no distortion.

UNLIMITED PRECISION P.A.W.™ is Precision Aluminium Welding. A new intelligent arc welding control on very thin thicknesses from 1 to 2mm. The result is very short and concentrated welding arc with the use of 1.0mm wire.
It is therefore possible to save the expensive push-pull torches and avoiding small wire diameters that are difficult to find and expensive. (Only for 303P / 303S P).

PROGRAMS: There are 12 programs dedicated to aluminum. Programs are synergic and pulsed. Two P.A.W.™ programs (AlMg5 and AlSi5) are available for thin material thicknesses from 1 to 2mm.

PULSE: The synergic pulse preset by the program helps the operator in welding materials such as aluminum.

SHORT ARC: The P.A.W.™ programs allow to obtain a short, highly concentrated arc by helping the operator during welding of thin materials. The absence of spatters makes welding very clean and controlled.

ALUMINUM: Thanks to P.A.W.™ technology, the IRON-MIG power source can weld with AlMg5 and AlSi5 aluminum wires , avoiding the use of expensive push-pull torches and small diameter wires.”
