Esab Welding & Cutting Products showcases the Swift Arc SL system, a side-load robotic cell featuring a new tandem Swift Arc Transfer (SAT) MIG welding process. The cell is said to achieve travel speeds well beyond the limits of normal spray arc welding for high productivity automated welding, due in part to the tandem SAT process, which uses twin welding wires running simultaneously through the cell’s robotic torch to deliver high deposition rates.
The MIG welding process produces flat welds with good penetration and without undercut, yielding in higher productivity. Its low heat input results in less deformation, and less part deformation and limited spatter minimizes post-weld labor, resulting in lowered production costs.
Dual trunnions manipulate parts from two sides, enabling welded parts to be unloaded and new parts to be loaded during the welding process. This continuous “arc on” time improves output by reducing downtime, according to the company.
It uses AristoRod non-copper coated wires to reduce contamination of the feed system with copper particles. According to the company, this results in dependable feeding properties and a stable arc at high welding currents and wire feed speeds.
The system is equipped with the Aristo RT robotic torch, which is said to have the highest TCP (tool center point) of any robotic torch, ensuring reliable operation.
Additionally, the cell comes with a supply of Endless Marathon Pac, a bulk wire drum system that provides continuous, in-line wire supply source, said to virtually eliminate the need to stop for wire changes.
The system is part of the Swift Arc series of robotic welding cells available in four models: Swift Arc AL (angle-load), Swift Arc FL (front-load), Swift Arc SL (side-load) and Swift Arc ML (mobile learning) robot cells. Each system is designed to be an economic configuration for a complete work cell that is delivered ready-to-weld.
The system is designed for the robotic welding of large parts at high production rates.
