4.3.1. Peak Level
The peak level is set by the voltage control at the power supply. Because the
peak level must be well into the spray arc region, it must be set substantially
higher than non-pulsed operation (typically 30-40 volts).
4.3.2. Background Level
The background level (typically 30 to 130 amps) is the result of the fixed design
values in the Pulse+, together with the power supply input voltage, wire feed
rate, and other parameters.
4.3.3. “On Time”
To obtain the one drop transfer during the peak level, the “On” time must be
varied, depending on the wire diameter. As the wire size is increased, so must
the “On” time be increased to burn off the larger size wire, Figure 4.
The “On” time is variable from 1 to 10 Ms.
4.3.4. “Off Time”
With the “On” time set to provide a smooth transfer, the “Off” time is used to
control the amount of heat. Decreasing the “Off” time moves the pulses closer
together (more heat), while increasing the “Off” time moves the pulses further
apart (less heat), Figure 5.
The “Off” time is variable from 1 to 20 ms.
