The ERG Series provides a perfect rotating ground contact to meet the most demanding applications. The adaptability of its design offers an abundance of robust mounting options to deliver the highest quality solution.
Suitable for all environments and applications including rotary welding, electro-plating, electro-polishing, cutting, and other high-current rotating industrial applications, the ROTOCON ERG Series is designed to withstand 100% duty cycles in continuous manufacturing and production processes, without interruption or downtime. The ROTOCON’s brush-free design eliminates all issues such as maintaining brush contact and conductivity, does not require application of conductive greases, and eliminates elevated contact resistance associated with conventional brushed rotary grounds.
The Importance of Low and Stable Contact Resistance While Selecting a Rotary Ground / Welding Clamp
An imperative concept in the design and use of rotary grounds is contact resistance. Contact resistance is the measurement of electrical resistance between two points. Everything electrically conductive has some amount of contact resistance, typically a more conductive material will exhibit less contact resistance. The ERG-400 exhibits less resistance than competitors and more consistent in how that resistance is exerted. By delivering a consistent and stable current delivery, Meridian Laboratory products ensure improved results and a lower margin of error. In the demonstration, you will see this is the case.
Since 1963, ROTOCONs have been relied upon to exceed even the highest industry demands, with tens of thousands of units sold worldwide. ERG rotary ground clamps are made available as RoHS / CE compliant while still delivering the legendary quality and durability that ROTOCON customers have come to expect.
Stop Settling for Less, It’s Time to Upgrade from Your Problematic Lenco and Tweco Brands
Brushed rotary ground clamps and other traditional products on the market provide poor grounding capabilities, constant grease maintenance, and high arcing potential. This leads to machines operating at decreased current levels with variances in penetration, weld quality, and ultimately scrapped product.
