Section 5 PARAMETER SET-UP
5.1 Peak Level
The voltage control on the power supply is used to set the peak level. The
melting temperature of the filler wire used determines at what point the voltage
should be set. For example, 4043 aluminum may require as little as 30 peak
welding volts, whereas steel and stainless may require 35-38 peak welding
volts, Figure 7. When trying to weld thin material the peak voltage should be
kept as low as possible without losing the spray transfer.
5.2 “ON” Time
The “On” time dial is used to obtain a smooth transfer. Start with an “On” time
of 2 ms, and adjust until the correct transfer is achieved.
5.3 “OFF” Time
Start with an “Off” time of 6 ms. If the weld is too cold, decrease the “Off” time.
If the weld is too hot, increase the “Off” time. Remember that the wire feed
speed must also be increased and decreased accordingly
NOTE: The required open circuit voltage (OCV) may vary from one power supply to
another, depending on the slope of the power supply. Sample parameters can be
found on the nest page.
