3.2 Duty Cycle and Over-heating
The letter ‘X’ stands for duty cycle,
which is defined as the proportion
of the time that a machine can work
continuously within a certain time (10
minutes). The rated duty cycle means
the proportion of the time that a
machine can work continuously within
10 minutes when it outputs the rated
welding current.
The relation between the duty cycle ‘X’
and the output welding current ‘I’ is
shown as the figure on the right.
If the transformer over-heats, the heat relay inside will open and send an instruction to
the circuit board, cut AC relay and the output welding current. The over-heat pilot
lamp in the front panel is lit.
At this point, the machine should be turned off for 15 minutes to cool the fan. When
operating the machine again, the welding output current or the duty cycle should be
reduced.

§3.2 Duty cycle and Over-heat
The letter “X” stands for the duty cycle, which is defined as the proportion of the time that a
machine can work continuously within a certain time (10 minutes). The rated duty cycle means
the proportion of the time that a machine can work continuously within 10 minutes when it
outputs the rated welding current.
The relation between the duty
cycle “X” and the output welding
current “I” is shown as the right
figure.
If transformer is over-heat, the
heat relay inside it will open and will
output an instruction to circuit board,
cut AC relay and the output welding
current, and brighten the over-heat
pilot lamp in the front panel. At this
time, the machine should be relaxed for 15 minutes to cool the fan. When operating the machine
again, the welding output current or the duty cycle should be reduced.
