1. Introduction
This manual provides explanation based on the following systems below. If individual systems on sites are different, the site workers are required to follow the manual to meet their requirements.
Specifications of the system used in this manual
Robot-gun (Welding gun change):
Servo-gun (G1), Servo-gun (G2), EQless-gun (G3), Eq-gun (G4)
Stationary-gun: Servo-gun (G5), Servo-gun (G6), EQless-gun (G7)
(1) Servo-gun
This gun carries out squeeze and opening operation by delivering the turning force of the servo motor to the ball screw to operate GUN TIP, and is used by setting it as an additional axis of the robot. The robot will carry out the equalization process during welding operation.
(2) Eq-gun
A spot-gun that carries out squeeze and opening operation by air pressure, the Eq-gun controls welding operation with welding condition and welding (applied current) output signal, and mechanically carries out the equalization process at the time of welding operation.
(3) EQless-gun
A spot-gun that carries out squeeze and opening operation by air pressure, the EQless-gun controls welding operation with welding condition and welding (applied current) output signal. As this gun does not have a cylinder that will carry out equalization at the time of welding operation, the robot will carry out the equalization process.
