The Weller WXA2 Dual Channel Digital Hot Air Station Power Unit provides the ultimate in temperature precision and performance. The standard power-sharing feature offers the flexibility to simultaneously operate any WX series tool, or combination of tools, with up to 255 watts of total power output. The WXA2 station also acts as a "benchtop controller" to communicate with other Weller external devices such as the Weller WHP1000 / WHP3000 pre-heating plates or the Weller Zero Smog 4V/6V Series solder fume extraction units. An external compressed air supply with 58 to 87 PSI is needed to deliver the hot air for the WXA2 series stations. Unlike traditional units that are continuously powered while in operation, the Weller WXA2 includes a Standby Temperature mode, which monitors the use of your Weller soldering iron and automatically sets the tool and peripheral devices to a lower temperature. The Auto Off feature can also be used to allow the unit to go into a Sleep mode when not in use. These innovative features reduce energy consumption, increase the life of the heating element and nozzles, and improve overall safety for users. The WXA2 combined with the WXHAP200 (sold separately) is ideal for professional repair or rework on state-of-the-art electronic assemblies in the industrial manufacturing, repair and laboratory sectors. The Weller WXA2 Hot Air Station System delivers unprecedented versatility, performance, power and peripheral management on one single platform solution.
