Optrel E650 is an optimum tool for most welding processes. In addition, Optrel E650 has a special spot welding function that significantly improves the efficiency of this process. For spot welding or bonding of welded components, the TACK mode provides greater comfort for the welder. In the TACK mode, more energy is automatically supplied to the filter so that the welder has a very quick and clear vision of the processed material after weldingis finished (shade level 4). During spot welding, the danger of processed materials igniting and related dangers can be eliminated almost completely. The TACK mode allows for reliable execution of up to 3 welding spots per second.
