* The Taylor-Winfield Corporation recommends Buss Fuse type LPN or LPS
** The Taylor -Winfield Corporation recommends Gould Shawmut Fuse type A4BX

CONTROL OPERATING VOLTAGE will be the same as welder power supply unless otherwise specified. Initiating switch voltage is 24, and solenoid valve voltage is 115.

TRANSFORMER SECONDARY VOLTAGES and other electrical characteristics will be furnished as shown above, unless otherwise specified.

THE TAYLOR-WINFIELD CORPORATION recommends the above indicated fusible isolation switches and cable sizes, but purchaser should check local and state electrical code requirements.

Short circuit current measurements are taken at 3" spacing between top of lower horn and bottom of upper electrode holder using electrodes in the welder.
