Load rate:

The load ratio refers to the ratio of the actual load of the transformer to its capacity, which is used to reflect the load-bearing capacity of the transformer and whether its operation curve is between the optimal 75-80%.

Load Duration Rate:

The duty cycle, also known as the duty cycle, refers to the ratio of the duration of the arc welding power source to the cycle time. Full cycle time, or duty cycle, includes load duration and rest time. The period specified in the national standard is Smin, 10min, 20min and continuous. The national standard stipulates that the rated load duration rate of manual welding is 60%, and that of automatic or semi-automatic is 60% and 100%. For example, the rated current of 500KR2 welding machine is 500A when the rated load duration rate is 60%. When the actual load duration rate is 100% (automatic welding), its maximum welding current is ≤387A.

Buzzer:

Buzzer is an electronic sounder with integrated structure. It is powered by DC voltage and is widely used as a sounding device in electronic products such as computers, printers, copiers, alarms, electronic toys, automotive electronic equipment, telephones, timers, etc. . Buzzers are mainly divided into two types: piezoelectric buzzers and electromagnetic buzzers. The buzzer is represented in the circuit by the letter "H" or "HA" (the old standard used "FM", "ZZG", "LB", "JD", etc.).
