Provide protection from electrical shock when direct grounding of the secondary circuit is not practical. Typical applications are Portable Welding Gun installations, Transgun installations for robots or Series Welding and Push-Pull welding circuits in multispot welders. Can be used with any resistance welding transformer, regardless of make, model, or age. Available in several sizes and voltage ranges.
Designed for an operating voltage which will be equal to or higher than the maximum secondary voltage of the welding transformer and a ground conductor size which must be equal to or larger than required by the National Electric Code.
