A double electrode (dual seam electrode) consists of two parallel welding electrodes mounted on a holder. It is used for creating channels, which is helpful for example when welding truck covers that will be equipped with different types of straps. It saves time since it welds two seams simultaneously and it helps improving the final product’s appearance since the two parallel welds will always be at the same distance from each other.
The double electrode is available with either standard, soft, lamella or soft lamella electrodes and the distance between the two welding electrodes can either be adjustable or fixed.
