2.4. Manually opening and closing the welding gun, and manual squeeze

 

The procedure for manually opening and closing the welding gun and performing manual squeeze is as follows.

 

(1)   Confirm the manual mode. Make preparations for operating the servo-gun axis if the servo-gun is used.

 

(2)   Select the gun number for manual open and close or squeeze. The gun number is selected as follows:

Single-gun	For welding gun change	R358 (Welding gun connection/disconnection)
	Not for welding gun change	R210 (Welding gun selection)
Multi-gun		R214 (Simultaneous welding gun selection)

 

(3)   Confirm if the following [user] key is registered.

Servo-gun		Air gun
Manual open and close	Manual squeeze	Manual open and close	Manual squeeze
			[GUN] key (Provided in key pad)

 

(4)   By pressing “[SHIFT] and [user]” key together, the movement described below will be carried out. If multi-gun is selected, all guns will be operated in a uniform manner.

 

Servo-gun	Air gun
	Manual open and close	Manual squeeze
	Opening and closing air gun (X1 ~ X4) Output assigned signal	Executing welding process (W1 ~W4) Output assigned signal   Welding condition (W1~W4) Output assigned signal

 

If using the servo-gun, the gun will display the following characteristics at the time of manual open/close and squeeze operation.

 

l The operation will be stopped automatically at the location where large open stroke, small open stroke and squeeze force reach their set values.

 

l The moving speed is 『2: Step fwd/bwd max. speed』 of 『[F7]: Condition setting』.

 

l Set the appropriate squeeze force, as the operation will not be successful if the set squeeze force is too small. (R211: Squeeze force setting)

 

l When using multi-gun mode with different moving distances for the two guns, the gun that arrives first will be stopped, and the other gun will be stopped after moving the remaining distance.
