BUSINESS Full Digital CO2/MAG Welding Machines Enhanced Low-Spatter Performance Stainless Pulse S-UW2 Weldtarocess Full software control elaborated in TAWERS. Stable CO2 welding from thin to thick plates! IA waveform control that stabilizes droplet transfer in CO2 welding Dotted line: CO2 welding CO! welding process (conventional model) I 1 1 u Process of droplet transfer ©Initial short-circuit control Detects initial short-circuit and then the secondary switching circuit reduces weld current rapidly to prevent micro short circuit that causes spatter. ©Neck control Detects a neck of the droplet and then the secondary switching circuit reduces weld current rapidly to prevent fuse effect that causes spatter. ©MTS control Suppresses weld pool oscillation at the time of short-circuit and short-circuit release. Also suppresses micro short-circuit during arcing time. A waveform control that reduces spatter in MAG welding Equipped with TAWERS's SP Control praised by many of our customers • Reduced spatter (Reduced removal work) • Shorter short-circuit cycle suited for high speed welding • Shorter arc length for good bead appearance ©Initial short-circuit control Detects initial short-circuit and then the secondary switching circuit reduces weld current rapidly to prevent micro-short circuit that causes spatter. ©Neck control Detects a neck of the droplet and then the secondary switching circuit reduces weld current rapidly to prevent fuse effect that causes spatter. ©SP control Superimposes the current immediately after a short circuit release and allows for higher wire-melting speed. This makes the next short-circuit smooth and also makes the short-circuit cycle shorter (from from To to Ti). HD-Pulse lAfolflinpf Dedicated characteristic for 500GZ4 wl\JII I® Rated output: 400 A at 100 % (pulse welding) Equipped with TAWERS's HD-Pulse process. Best for high quality and high speed welding of medium and thick plates. • Preventing undercuts during high speed welding. • Dip (Short circuit) transfer enabling lower heat input with gap handling capability. • Precisely controlled dip timing reducing spatter. o» Droplet transfer: •One drop per one pulse •Drop transfer

►Connection cables *1: Use 3P type dedicated torches tor GZ4 series. *2: Rated duty cycle of pulse MAG welding: 20 % at 350 A •Gas regulator ►Welding torches*1 3-pin type torch switch receptacle (3 m: dedicated torch) GZ4 can be used for low-spatter robotic or automatic welding! *3: Terminals for connecting ammeter, voltmeter, and flow meter are standard on jig terminal block of welding power source. To use "Stop", "Emergency stop", and "Current detection", this optional unit is necessary. *4: To use GZ4 with Panasonic welding robot, this optional init is necessary. *5: This optional unit is...
