7. This knob is active in the MIG/MAG mode only and allows selection between two arc types.
When the led above the knob is lit a softer welding arc for MIG brazing is obtained.
When the led is dark the normal, slightly crisper or harder arc is obtained.
8. Mode selection
2 step wire welding
• Bring the torch close to the piece you mean to weld.
• Press (step 1) and hold the torch button.
• The wire advances at closing speed until it contacts with the work-piece. The
welding arc is lit and the set wire feed speed will continue at set speed.
• Release the button (step 2) in order to start the welding completion procedure.
• The supply of gas continue for the selected post-gas time
4 step wire welding
• Bring the torch close to the piece you mean to weld.
• Press (step 1) and release (step 2) the torch button.
• The wire advances at closing speed until it contacts with the work-piece. The
welding arc is lit and the set wire feed speed will continue at set speed.
• Press (step 3) and release (step 3) the button in order to start the welding
completion procedure.
• The supply of gas continue for the selected post-gas time
MMA (stick) welding
In this mode a constant current characteristic for MMA welding is set and the
terminals are live (10V).
An automatic hot-start enables easy arc start. And an automatic arc-force maintains
a smooth and stable arc by momentarily increasing the current if bigger droplets in
the arc tends to produce short circuits.
An automatic anti-stick function will cut the power if the electrode should get stuck in
the melt-pool so that it can be removed without damage.
2 step TIG welding
• Touch the electrode to the piece you mean to weld.
• Press (step 1) and hold the torch button. Shielding gas and very small “signal”
current will start flowing.
• Lift the torch slowly, and the signal current will initialize an arc and an up-slope
function that increases the current to set value.
NOTE: The arc must be started within 3 seconds, if not the signal current will be
stopped to protect the circuit and a new start cannot be done before gas supply
has stopped.
• Release the button (step 2) in order to start the slope-down function that gradually
reduces the welding current to zero.
The supply of gas will continue for the selected post-gas time
