1 Spot Welding Application Using a Motor Gun
1.9 Manual Pressure
1-76
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
condition specified by “PRESSURE FILE NO.”
PRESSURE : It is defined by the dry spot pressure file
condition specified by “PRESSURE FILE NO.”.
• When “CST PRESS” is selected
TOUCH SPEED: It is defined by the value input to
“CONST PRESS TOUCH SPEED”.
PRESSURE : It is defined by the pressure input to
“CONST PRESSURE”.
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.
16. WELD GROUP OUTPUT(WGO)
Specifies a welding group No. output to the welder.
For the details, refer to chapter 1.13.7 "Welding Conditions Group
Output Function"
•Touch motion :
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.
•1ST PRESSURE :
Start-up the welder at the same timing with
the execution of the1ST PRESSURE.
•2ND PRESSURE :
Start-up the welder at the same timing with
the execution of the 2ND PRESSURE.
