- Pneumatically-operated suspended gun with integrated TE300, TE470 or TE480 microprocessor-based welding controls.
- Intelligent Design, Small Dimensions, and High Welding Capacity deliver Maximum Productivity.
- High electrical efficiency.
- The totally-enclosed unit includes rubber bumpers in some areas, for safe and easy operation.
- Accurate maneuverability at any angle is guaranteed by gyro suspension mounted on sealed bearings, coupled with a TECNA balancer.
- Rotation lock allows the locking of multiple axes of motion.
- Accepts a broad range of standard and special arms to accommodate special applications. “C” type gun assists in accessing unconventional areas.
- Chromium copper electrode holders offer long life in a production environment and are designed for use at angles of up to 30°. Ask about WSI-exclusive 30-degree arms!
- Long, adjustable Welding Stroke enables welding in difficult-to-reach areas, including welding reinforcements and ribs.
- Temporary extra stroke (retraction stroke) allows for reaching into tough spots.
- Water-cooled transformer, with epoxy resin-coated windings for long life.
- Water-cooled arms, electrode holders, and electrodes for best performance and maximum use.
- SCR (Silicon-Controlled Rectifier) is insulated from the cooling circuit and includes a thermal cutoff switch for overheat protection.
- Lube-free chromium-plated cylinder and shaft offer a long service life in a production environment.
- Lube-free pneumatic circuit eliminates oil mist in your shop.
- Trigger Handle Safety prevents accidental initiation.
- Trigger Handle Controls enable selection between 2 or 4 welding programs, as well as Stage 1 ‘weld / no-weld’ function.
- New for 2017: Power Supply Cable is replaceable without opening up the welder!
