The letter "X" represents the working sky, which is defined as the proportion of time a machine can work continuously
within a period of time (10 minutes). The rated working limit is the proportion of time a machine can run continuously
for 10 minutes when the rated welding current is output. The relationship between the working limit "X" and the
welding current output "l" is shown in the figure.
