A product listing from Swagelok in the January issue included an incorrect photo. The product release and correct photo are below.
“Orbital welding power supply”
Swagelok Co. released the Swagelok welding system M200 power supply that offers a 200 amp capability at a weight of less than 50 lbs. (23 kg). A high-resolution, 12.1 in. (307 mm) color industrial touch screen gives users a pathway to enter weld programs. Users can choose from one of three forms to enter weld programs, including automatic weld schedule programming. The M200’s automatic shield gas control (patent pending), simplifies set-up of shielding gas, requiring no use of a separate flow meter.
Multi-language capability is built in to the M200, requiring no separate programming or special ordering. Built-in languages are English, French, German, Spanish, Japanese, Korean, and Chinese (simplified and traditional). Universal voltage input (100 to 230 V) requires only a cord/plug change to accommodate an input voltage.
The M200 works with all currently available Swagelok weld heads. It includes four USB ports, Ethernet port, USB device (output) port, VGA output, and serial port. All gas and electrical connections, plus the integral, high-speed thermal printer are easily accessed from the unit’s side panels.
