ROTOCON ERG Electrical Rotary Grounds are 100% Maintenance-Free. The flexible design offers a number of robust options and mounting variations to meet your exact specifications. 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.
