3.1. Tool No. corresponding to Gun No., and gun-type set
Set the tool number and the gun type that corresponds to the spot-gun number. As welding methods vary according to the gun type, the tool number and the gun type should be set correctly.
(Cautions for setting Stud-gun) Set the gun type as “Stud” only if the tool attached on the robot R1 axis is Stud-gun. It should be selected as “Eq” if spot welding is being executed with a stationary stud-gun.
As an example, in the setting shown in the screen above, G1 ~ G4 are set to use the welding gun change function, so the same welder will be used. Therefore, it should be set as one welding system (W1). If guns G5 ~ G7 are stationary guns, these gun numbers are irrelevant to the tool number assigned to the robot, so the tool number for all guns can be set as “4,” which is the last tool number used for welding gun change. In addition, the welder can be set in the manner that each individual welding system (W2 ~ W4) will be assigned.
Set a gun type corresponding to the gun number as in the screen above, according to the system specifications discussed in this manual.
Tool refers to an object that will be connected with the R1 axis hem of the robot. Therefore, a separate tool number should be assigned to each welding gun change (robot-gun) without duplication, since each of these guns has a different weight and appearance. G5 ~ G7, which are stationary guns, do not connect to the R1 axis hem, so these can be set at the user’s discretion. (All tool numbers are set to “4” in the screen above)

l If a tool to be used does not support spot-gun, set all other guns to the tool number assigned to the last gun, so that this tool number is used for other purposes. That is, when making the setting as shown in the screen above, there is no gun number corresponding to “T5 ~ T15”, so T5 ~ T15 can be used for other purposes.
l When setting the gun type as servo-gun, the additional axis number corresponding to the gun number will be matched in the following way.
Gun number | Gun usage | Additional axis number |
G1, G2 | Welding gun change, including servo-gun | Additional axis 1 |
G5 | Stationary Servo-gun 1 | Additional axis 2 |
G6 | Stationary Servo-gun 2 | Additional axis 3 |
