To prevent burn through when welding thin metal, Miller Electric Mfg. Co.™s Syncrowave® 250 DX and 350 LX AC/DC TIG welders now have improved low-end DC TIG arc starting capabilities. While Miller recommends using a 1/6-inch or smaller diameter tungsten electrode for low-amperage arc starts or for welding thin materials, the power source™s improved arc starting circuit also provides positive arc starts with larger 3/32-, 5/32-, and 1/8-inch diameter tungsten. The Syncrowave™s new low-end arc starting circuit also increases operator convenience and productivity because welders can standardize on one tungsten diameter instead of switching tungsten sizes based on welding amperage and base metal thickness.
Other major enhancements include a totally redesigned cooling system, the optional Coolmate® 3X, which provides superior heat dissipation and coolant circulation with all styles of TIG torch configurations and cable lengths. The Coolmate 3X features easy maintenance access and a flow meter on the front of the unit to confirm coolant flow.
To simplifying ordering and eliminate the chance of over-looking component, Miller now offers a Syncrowave TIGRunner® Complete package, which includes a Syncrowave 250 DX or 350 LX welder, Coolmate 3X cooler, water-cooled torch kit, 4 gallons of free factory coolant (an $80 value), a gas regulator and accessories. Miller™s factory coolant uses a proprietary blend of conditioners
