Energy Method
In this method, weld duration is controlled by the amount of energy input into the weld joint as determined by the spin torque and angular rotation. The welder will maintain a constant spin speed until the programmed energy is produced. Then the tool will decelerate and stop. The Weld Parameters button is used to enter the settings shown in Figure 5-16.The Energy (J) field specifies the weld energy in Joules. As a safety measure, using the Energy Method requires that the Weld Time Process Limit be enabled (To set this limit, refer to the Process Limits description in the POST-WELD menu later in this manual.). If the Upper Weld Time Limit is exceeded during the weld, the machine will stop the cycle and report an error. The VERT Speed (mm/s), SPIN RPM, and Dir. fields are the same as in the Time Method.

WELD OPTIONS
Several weld options are available, any combination of which may be enabled simultaneously.
Orientation Option
With this option you can specify the upper tool’s angular stopping orientation at the end of the weld. To enable it, press the Orientation button and then the Enable box on the screen shown in Figure 5-17. The final weld orientation is defined in the Weld field. Two methods set this value: 1) direct numeric entry into the Weld field, or 2) visual alignment by jogging the spin tool to the desired orientation. To jog the spin tool, select the SPIN Jog Speed (Low, Medium, or High) and the jog direction (JOG + or JOG -). Then activate both RUN switches to rotate the tool. The current spin tool orientation is shown in the Jog Pos.. (Deg..) box. Once the head is in the desired orientation, use the Transfer arrow button to set this value as the final Weld orientation. To aid in visually setting the orientation, the press can be jogged vertically by selecting the DOWN or UP buttons and activating both RUN switches. The Move To button allows the spin tool to be rotated to the programmed Weld orientation. After selecting this button, activate both RUN switches until the spin tool stops moving. Press DONE to return to the main WELD tab screen.
