SUSPENDED GUNS

Available in stock
SKU: 3321-3328

Description

MAIN WELDER FEATURES Pneumatic operated suspended gun, with integrated TE300 or TE470 microprocessor welding control unit. High productivity achieved with rational design, reduced dimensions, high welding capacity. High electric efficiency. Reduced installation costs. Totally enclosed, rubber protected for easy and safe operation. Gyro suspension on sealed bearings together with a spring balancer guarantees accurate manoeuvrability at any degree. Rotation locking device. Large selection of arms, enabling to set-up the welder according to the work exigencies. Chrome-copper electrode-holders for heavy duty and long life, designed for both straight and angled assembling. Adjustable electrodes distance, adjustable short working stroke for heavy duty. Temporary extra stroke to reach the areas to be welded. Long working stroke to weld reinforcement ribs, jobs in areas difficult to be reached. Water-cooled transformer, with epoxy resin coated windings. Water cooled arms, electrode-holders and electrodes. Synchronous SCR contactor insulated from cooling water circuit with protection thermostat. Oiless chromium plated cylinder and shaft for heavy duty operation and long life
