When the AC welding current is 16000 A or less,
the operational distance between the
welding conductor and the cylinder/
actuator or auto switch can be
0
mm
.
For use with single-phase AC
welders. If it is used for cur-
rent inverter welders (includ-
ing rectifying type) and con-
denser type welders, the
magnetic field resistance is
reduced. Please contact SMC
regarding the performance.
Mounting position can be easily
adjusted with
2-color indication
.
Non-polar type,
with
Short-circuit protection
Use of
Standard
Auto switch mounting bracket
2-color display
solid state auto switch
Spatter proof
flame resistant cable
Pre-wired connector (M12)
Improved maintenance ability
As an auto switch mounting bracket is
fixed on the cylinder/actuator side, the
position does not need to be readjusted
when the auto switch is replaced.
