Auto Switch Specifications
 It is possible to use in an
environment which generates
a magnetic field disturbance
(AC magnetic field).
 A proper operating range can
be determined by the color of
the light.
(Red → Green ← Red)
Precautions
Caution
For single-phase AC welding machines
If it is used for current inverter welders
(including rectifying type) and condenser
type welders, the magnetic field resistance is
reduced. Please contact SMC regarding the
performance.

Magnetic Field Resistance
If the current of the AC welding machine is 16000 A or lower, the auto switch can be used, even if the
distance between the welding conductor (gun cable) and the cylinder/actuator or auto switch is 0 mm.
Please contact SMC when the AC welding current exceeds 16000 A.
