If a new procedure is being developed, and there is no previous data available regarding the expected

welding current, these steps should be followed.

11.1 Enter the Main Screen - Admin Function Active (See SECTION 3.1.0)
11.2 Configure a weld pass as closely to the expected values as possible. This data should

be acquired from reliable industry product data. The values for the minimum, maximum

range for the current should be set such that these values will allow a considerable range

of adjustment. The startup and crater times should be set to very low values so that the

Automatic Height control will not be given time to make erratic adjustments prior to the

welding phase of operation.

11.3 Turn the Automatic Height Control (See SECTION 4.9) off and perform a weld, manually

controlling the height axis to give a proper amount of contact tip to work distance..

11.4 While making the weld and with the height adjusted to an acceptable position as found

in SECTION 11.2, observe the control box and record the current being displayed. (See

SECTION 4.4) during the weld.

11.5 Stop the system.
11.6 Adjust the current using the Current Switch on the pendant (See SECTION 5.1.E or 5.2.F

depending on the pendant being used.) so that the Current Value displayed on the Run

screen (See SECTION 4.2) it is close to the average current observed during the weld

performed in 11.3 above.

11.7 Turn the Automatic Height Control on (See SECTION 4.9).
11.8 Perform another weld, making small adjustments to the current if necessary.
11.9 Save the pass. (See SECTION 4.10)

11.10 Edit the startup/crater current values so that they provide the required contact tip to work

distance for the given wire feed speed.
