When using WiseSteel, different adjustment methods are applied at different power ranges (different arcs). Within the
short arc range, WiseSteel is based on adaptive short arc control; that is, the process adjusts the short circuit ratio. This
creates an easily-adjustable arc and less spatter. Within the short arc range, the shape of the current is similar to the tra-
ditional short arc welding. When a short arc is used in vertical up welding where weaving motion is applied, WiseSteel
ensures good quality through adapting to the changes in the stick-out length.
Using WiseSteel on globular arc range means that WiseSteel fluctuates the power between short arc and spray arc at a
low frequency, so that the average power stays within the globular arc range. This results in less spatter than con-
ventional globular arc welding, and a welding pool that enables excellent structural durability.
Within the spray arc range, WiseSteel is based on adaptive arc length control, which keeps the arc optimally short.
WiseSteel also utilizes micro-pulsed welding current. This creates a well-formed weld pool that enables excellent bead
geometry and optimal penetration with smooth and durable joints, and speeds up the work. The pulsing is not notice-
able to the welder. The shape and control of the current are close to the conventional spray arc welding.
To take WiseSteel into use, select Settings > Wise features > WiseSteel.
To adjust the welding power/wire feed speed while welding, in the Control Pad's Welding view, turn the left knob.
To fine tune heat output while welding, in the Control Pad's Welding view, turn the right knob.

The wire feed speed / current indicator shows the arc range:
1. Short arc
2. Globular arc
3. Spray arc
The adjustment method is different for each range.
Wise features: introduction to WisePenetration+
In standard MIG/MAG welding, changes in stick-out length cause welding current to fluctuate. WisePenetration+ main-
tains constant welding current by controlling the wire feed speed according to the stick-out length. This ensures stable
and effective penetration and prevents burn through. WisePenetration+ also adjusts the voltage adaptively, which keeps
the arc focused and optimally short. WisePenetration+ enables welding with Reduced Gap Technology (RGT) and is com-
patible with 1-MIG and Pulse welding processes.
