2.1.2 External dimensions
This section explains the external dimensions of the welding power source.
2.1.3 Rated duty cycle
This section explains the rated duty cycle of the welding power source.
• Use this welding power source at or under the rated duty cycle.
Exceeding the rated duty cycle may result in deterioration and damage to the welding
power source.
• Periodically blow moisture-free compressed air to clean dust and dirt accumulated on
the transistor and radiation fin of the diode.
If dust and dirt accumulate on the radiation fin, it may not only reduce the duty cycle
but also result in degradation or burnout of the welding power source.
• The rated duty cycle of the welding power source is as
follows.
At TIG welding: 350 A/24 V 40%
At STICK welding: 250 A/30 V 40%
(Rated duty cycle of 40% means the power source must be
rested for 6 minutes after 4 minutes of continuous welding
at the rated current.)
