ST-ARC™ is the intelligent control of the Short Arc process, capable of handling automatically allvariations within the welding process.

The result is a short concentrated and stable arc 100% easier to control. The dynamic cold welding
characteristics significantly lower the heat input reducing distortion, spatters, re-working and cleaning
plus less weld time.ST-ARC™ is a standard feature of all Stel MIG / MAG Stel welders.

SELF 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.

START CONTROL


The approach speed of the wire to
the piece and welding dynamics are
synergic and provide limit spatters
at the start with every material.
The dynamic synergic technology
provides for an extremely smooth,
spatter free Arc Ignition with all
materials.

VERTICAL POSITION


In a vertical UP position allows welding of thin material with separation up to 5mm gap.

THIN MATERIALS


Provides a smooth, controlled arc too
at the lowest parameters with few spatters,
good weldability of the edges, heating and
reduced deformations for thin materials.

PAW™ is Precision Aluminium Welding. A new intelligent arc welding control on very thin Aluminiumthicknesses from 1 to 2mm.

The result is a very short and concentrated welding arc using 1.0mm wire with a standard MIG
Torch.Therefore, there is no need for expensive push-pull torches, plus the additional cost saving of
using smaller wire diameters that cause problematic feeding.

PROGRAMS


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

PULSE


Preset synergic pulse programs
greatly assists the operator
with welding materials such as
aluminum.

ALUMINUM


Owing to PAW™ technology, the
IRON-MIG 221P power source can
weld AlMg5 and AlSi5 aluminum
wires avoiding the use of expensive
push-pull torches and smaller
diameter wires.

Normally pulsing is a “HOT” process. This has always caused problems of metal distortion (in particularthin 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 title 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.

i-Cold Pulse™

I-Cold: reduce heat input by improving performance

Find out how the Stel pulsed system reduces heat input by increasing speed by 35%.
Many have tried, Stel has succeeded.

Normally you know the pulsed welding in TIG and MIG, But not the pulse in electrode.STEL has been the first to develope this procedure with the range Max dp 171.-201C presented at ESSEN in the 2005.

Today this process has been studied and appreciated in all the European Universities of Welding.
The benefits

SELF COMPENSATION


> Better arc stability (expecially at low currents)
> Possibility to use the electrode with bigger diameter with thin materila thickness.
> Reduction of breakthroughs during welding with thin material thickness
> Better transfer control of the welding arc
> Easier control for the welder
> Improvement of the aesthetics of welding very similar to the Tig expecially with 4-5Hz frequency.

START CONTROL


> Ensures better and safer welding with gaps
> Ensures better penetration from both sides of the pipe
> Ideal for vertical up and vertical down welds.
