3.2. DUTY cycle & Over heat
The letter "X" stands for duty cycle, which is de ned 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 gure.
If the welder is over-heat, the IGBT over-heat protection unit
inside it will output an instruction to cut output welding
current, and brighten the over-heat pilot lamp on 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.
3.3. SOLDERING IRON POLARITY CONNECTION
