The Piranha Junior is a low cost 400 amp isolation safety switch, designed essentially for cutting operations, but of course can still be used for welding, but comes without amp or volt metres. The unit is housed in a smaller wall mounted steel enclosure, 300 x 250 x 200mm, but is light enough to be used as a portable/non-fixed unit. All Piranha Juniors come with DIN style cable connectors for quick and easy connections and a rubber sealing front closing door, and large easy to operate switching handle.
