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
