§3.2 Duty cycle & Over heat
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 right figure.
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 Movement and placement
Please take care for the welder when moving it, and do not make it sloped.
It also can be moved by the handle on the top of the welder. Place the welder well when
moving it to the right position. When the machine gets to the destination, it needs to be fixed
up to avoid gliding.
When using forklift, its arm length must be long enough to reach the outside so as to ensure
lifting safely.
The movement may result in the potential danger or substantive hazard, so please make
sure that the machine is on the safe position before using it.
§3.4 Power supply input connection
SKYTIG 2045 ACDC welding machines’ power supply connects to 220V.
