X8 MIG WELDER 2.5 Operation
Introduction to WiseSteel
The WiseSteel function is based on modifying the conventional MIG/MAG arcs to enable
higher quality of welds. WiseSteel improves the arc control, reduces spatter and helps create an
optimally-formed weld pool.
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 traditional 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 conventional 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 noticeable to the welder. The
shape and control of the current are close to the conventional spray arc welding.
Using WiseSteel
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.
