On Time, Pulses/Second, Background | Miller Electric KC237900

Pulsing operations may be performed when the PO- LARITY SWITCH is in either the ELECTRODE NEGA- TIVE or ELECTRODE POSITIVE position.

When remote control of the output amperage is employed, only the peak amperage level is remotely controlled; the background amperage level is still estab- lished by the position of the BACKGROUND control.

4-10. % “ON TIME” CONTROL (Pulser Models Only) (Figure 4-1)

% “ON TIME”

The % “ON TIME” control provides pulse width selection of the welding power source output amperage. The % “ON TIME” control is operational only when the PULSES switch is in the ON position.

Rotating the % “ON TIME” control in a clockwise direc- tion increases the peak amperage “on-time” relative to the entire pulse time; the balance of the time is back- ground amperage. Hence, this control establishes the peak amperage pulse width relative to the entire pulse width.

The scale surrounding the % “ON TIME” control is cali- brated in percent and does not indicate an actual time value.

IMPORTANT: This control may be adjusted while welding.

4-11. PULSES/SECOND CONTROL (Pulser Models Only) (Figure 4-1)

PULSES/SECOND

The PULSES/SECOND control provides pulse frequen- cy selection of the welding power source output amper-

age. The PULSES/SECOND control is operational only when the PULSES switch is in the ON position.

Rotating the PULSES/SECOND control in a clockwise direction increases the pulse frequency.

The scale surrounding the PULSES/SECOND control is calibrated in pulses per second to aid in the selection of a pulse frequency suitable for the application.

IMPORTANT: This control may be adjusted while welding.

4-12. BACKGROUND CONTROL (Pulser Models Only) (Figure 4-1)

BACKGROUND

The BACKGROUND and AMPERAGE ADJUSTMENT control provide amperage selection within the welding power source output amperage range being used. The setting of the background control establishes the back- ground level from which the output amperage travels to the pulse level established by the setting of the AMPER- AGE ADJUSTMENT control. When the AMPERAGE ADJUSTMENT control is adjusted to a setting above the BACKGROUND control, there will be positive pulse peaking from the background reference level. This unit does not have negative pulsing capability. The back- ground amperage is always a percentage of the peak amperage. If the peak amperage is adjusted (by means of the AMPERAGE ADJUSTMENT control), the back- ground amperage will always vary with it according to the percentage setting of the BACKGROUND control. The background amperage can never be higher than the peak amperage. Rotating the AMPERAGE AD- JUSTMENT control and BACKGROUND control in a clockwise direction increases the output amperage.
