6.10.2.5 F5: Maximum external command voltage
Set the maximum value of the voltage command inputted from the outside when using the welding
power source by setting the internal function F4 (Auto/Manual mode) to "1" (Automatic machine 1
mode).
Select one of 10 V, 12 V, 14 V and 15 V.
The graphs below shows the relations among the voltage command and the welding (base) current/
Pulse current
Use the following table as a guide. Due to the length and layout of the wiring such as external input line
(command voltage line) and the base material side/torch side cables, the actual output may differ from
the graphs below.)
6.10.2.6 F6: Hazard reducing function
The voltage reducing function is used for AC STICK welding and DC STICK welding. This is a safety
function to reduce the risk of an electric shock to workers by limiting the no-load voltage of the welding
power source to a low voltage when welding is not performed.
Therefore, if the welding power source is used in an elevated or narrow workplace, use it with the hazard
reducing function set to "ON" (Use).
The setting at the shipment from our factory is "ON" (Use).
• [ON]: This function is enabled.
• [OFF]: This function is disabled.
NOTE
•
When the welding power source is connected with Model K-300 (external type voltage
reducing device), set this function to "OFF".
