1 Spot Welding Application Using a Motor Gun
1.9 Manual Pressure
8. MANUAL DRY SPOT MODE
Pressurizing method for the dry spot is specified by selecting either
"FILE" or "CST PRESS". With this procedure, "TOUCH SPEED" and
"PRESSURE" are specified as follows.
• When "FILE" is selected
TOUCH SPEED: It is defined by the dry spot pressure file
PRESSURE : It is defined by the dry spot pressure file
• When "CST PRESS" is selected
TOUCH SPEED: It is defined by the value input to
PRESSURE : It is defined by the pressure input to
9. PRESSURE FILE NO.
This item appears when "FILE" is selected to "MANUAL DRY SPOT
MODE". Specifies the dry spot pressure file number for the manual dry
spot operations.
10. CONST PRESS TOUCH SPEED
This item appears when "CST PRESS" is selected to "MANUAL DRY
SPOT MODE". Specifies the touch speed for the constant pressurizing
operations.
11. CONST PRESSURE
This item appears when "CST PRESS" is selected to "MANUAL DRY
SPOT MODE". Specifies the pressure for the constant pressurizing
operations.
12. MANUAL SPOT MODE
"FILE" is always specified while executing the pressurizing operations
at the manual spot.
13. GUN PRESSURE FILE NO.
Specifies the gun pressure file number in welding operation.
14. WELDING CONDITION(WTM)
Specifies the welding condition number to be output to the welder.
15. WELDER STARTUP TIMING(WST)
Shows the timing to start-up the welder. Select one condition out of the
following three conditions.
•
Touch motion
:
•
1ST PRESSURE
:
•
2ND PRESSURE
:
16. WELD GROUP OUTPUT(WGO)
Specifies a welding group No. output to the welder.

condition specified by "PRESSURE FILE NO."
condition specified by "PRESSURE FILE NO.".
"CONST PRESS TOUCH SPEED".
"CONST PRESSURE".
Start-up the welder at the same timing with
the execution of SVSPOT instruction.
A squeeze time at the welder is required
because the welder starts its operation before
pressurization starts.
Start-up the welder at the same timing with
the execution of the1ST PRESSURE.
Start-up the welder at the same timing with
the execution of the 2ND PRESSURE.
