Key Features of Vacuum Tube Welder with Speed/ Power Control

• Alphanumeric display housed in remote control unit shows output power and fault messages.
• PLC for welder operating sequence and fault diagnostics.
• Speed /power control greatly reduces open seam tube through accurate weld power control on start-up and shut down
• Thyristor [SCR] power control with low ripple LC filter for smooth minimum weld bead at all power level
• Air cooled high voltage transformer eliminates leaks, toxics, inflammable or other problems associated with liquid cooled designs.
• Automatic load impedance matching system to achieve optimum matching condition at all loads-optimum efficiency with minimum operating cost.
