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. Globular arc range: · Globular arc 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. Spray arc range: · 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. For more information on Wise products, visit www.kemppi.com.
