Direct water cooling of the gas nozzle reduces the adhesion of weld spatter. The cooling water is routed through its own channels in the torch body up to the contact pipe, and from there through the nozzle stock to the gas nozzle.
igm torch exchange system
By means of this torch exchange systems the robot can automatically be equipped with torches of various geometries. This functionality is program controlled and can be applied wherever appropriate and needed. The torches to be used can be of different length or special shape, designed for better accessibility to narrow areas.
In any case the welding media are lead through the hollow shaft in the robot’s wrist joint offering the large working envelope and the outstanding performance of the robot when welding in narrow spaces of the work piece. The exchange system is designed in such a way, that the torch will be decoupled from the hose package.
The exchange system is designed to seperate the welding torch completely from all media of the hose package.
The torch magazine is mounted stationary on a stand or on a pillar. A variety of torches can be exchanged, whereby also switching between tandem and single-wire process is possible.
