Programming Levels/Segments Parameters
The Weld Schedule - Weld Levels screen displays weld
parameters that may be changed for each level. Once parameters for Level 1
have been entered, touch OK to save. Touching Add a Level will create
another level identical to the previous level. Select those parameters you
wish to change and enter the value from the keyboard.
Level Position: Enter the position of the electrode at the end of
the level. The time to arrive at that position will be entered auto-
matically once the travel speed has been entered.
Determination of Welding Currents
Primary Amps: Primary amps will essentially determine the
amount of weld penetration. Calculation of Primary Amps for Level
1 is based on wall thickness. The amount of primary amperage
needed will vary somewhat from heat-to-heat of stainless steel.
One Amp per 0.001” is a rough approximation. However, more
realistic amperage values are obtained using the corrections
shown in the table on the next page. Values are based on a travel
speed of 5 IPM.
Symbols for each parameter are shown at the left of the screen.
