Torch Kit shall include power supply and all necessary cables, fittings and any other accessories required for operation of the torch. Also included shall be a taper lock, 0.045" Contact tip. 5. Pneumatic Valve Kit MANIFOLD ASSEMBLY, ACCUFAST/LASER TARGET, 4-PORT MANIFOLD WITH MASTER CONTROL VALVE AND 2 CONTROLLED VALVES, NO FILTER REGULATOR - This pneumatic valve package is to be utilized with sensors such as Accufast. A primary valve should ensure air is provided to the sensor anytime servo power is applied. When servo power is removed or the "Power Save Function" is entered, the main valve shall close preventing air flow and saving on utility consumption. This package is to include two separate individually controlledvalves that are intended to be used on systems with wire brake(s). These valves provide individual control of wire brake(s) as controlled from the INFORM program. A single cable from the valve assembly to the robot controller shall handle all needed wiring and signaling. This kit is to include all required cables, hoses, and fittings to connect to system devices. 6. SOFTWARE ETHERNET/IP CONFIGURATION/MONITORING APPLICATION - Shall include Ethernet/IP configurationsoftware to find and configure Turk Ethernet/IP devices on the welding cell network. This software shall monitor and troubleshoot communications issues after devices have beenlinked. All required ethernet and other cables shall be included. 7. DRESS KIT, ARC WELDING, AR1440 MILLER AUTO CONTINUUM - Shall Include hardware and labor to dress the robot and function test the welding system an external feeder control for routing up the robot arm while shielding gas is supplied from the base of the robot to the wire feeder via the robot's internal hosing. The feeder cable and gas hose are to be supplied with the system. The torch lead is to be routed along the upper arm up to the feeder and is to be protected ata minimum by a leather cover. Robots shall be weld tested to verify proper operation. Power Source, wire feeder, and feed rolls are to be supplied with thesystem) 8. TORCH CLEANER - REAMER ASSEMBLY, TREGASKISSTT3, CLEANER/SPRAYER/CUTTER, W/O STAND - REQUIRES 1 START-UP KIT Tregaskiss Tough Gun TT3 Reamer with anti-spatter sprayer and wire cutter. This kit shall include an Ethernet/IP interface assemblyhoused in the post of the reamer. The interface is to allow Ethernet/IP connectivity to the reamer post but still utilizes the standard (non-Ethernet) reamer. 9. STAND, ACCESSORY, 915MM (36), TREGASKISS, W/ POSTMOUNT INTERFACE - This 4" tubular steel reamer post is to house a universal, compact Ethernet/IP enabled interface that is included as part of the reamer. Cables are to be secured to the post to ensure a clean installation. 10. ACCUFAST SENSOR Kit, ACCUFAST II, TREGASKISS, INSTALLATION - The Accufast II sensor shall utilize a class II (560 uW commercial 1-D laser instead of "touch" sensing with the weld wire. The sensor shall be wired into a rapid input on the robot for high accuracy material detection, and macro jobs to provide simplified programming with auto each ofprogrammed part location. Thesensor is to be housed in an enclosure with pneumatic shutter that opens when searching and closes to protect the sensor from the welding arc. The enclosure should maintain positive air pressure keeping smoke and other fumes out of the enclosure. A valve assembly mounted to the controller base provides the positive air pressure to the enclosure anytime servo power is applied. This valve is to minimize air consumption when the robot is not in operation or the "Power save function" activates. 11. PNEUMATIC VALVE KIT - KIT to Include MANIFOLD ASSEMBLY, ACCUFAST / LASER TARGET,4-PORT MANIFOLD WITH MASTER CONTROL VALVE AND 2 CONTROLLED VALVES, NO FILTER REGULATOR - The primary valve is to ensure air isprovided to the sensor anytime servo power is applied.
