OPERATING PRECAUTIONS
1.
Operating Environment
a.
The machine can perform in environments where conditions are dry with a max humidity of 60%.
b.
Ambient temperature should be between -10 to +40 degrees centigrade.
c.
Avoid operating machine in direct sunshine, rain, or snow.
d.
Avoid operating the machine in environments where there is pollution or high concentrations of dust or
corrosiveness gas in the air.
2.
Proper Ventilation
All users must ensure proper ventilation of the welder. The welder is powerful and compact which generates high
currents and heat. Wind alone cannot ensure proper cooling so it is advisable to place a fan to cool down the machine
during hot weather or continuous usage in order to keep the components working for a long shelf life. Make sure the
machines vents or built-in fans are not
blocked or covered and it’s receiving proper ventilation. Keep the welder at a
minimum of 30cm from any objects to ensure proper ventilation.
3.
Avoid Overvoltage
The specific power voltage can be found in the main technical specification chart listed above or on the rear plate of the
machine. The automatic voltage compensation circuit will ensure that the welding current is functioning in the correct
range. If the power voltage is exceeded from the max allowed value it will damage the components of the machine.
4.
Avoid Overloading
Limit the welding current strictly to the max allowable duty cycle. Do not exceed the max load because overloading can
damage and burn up the machine.
5.
Duty Cycle
Duty cycle refers to the percentage of the working time against a 10-minute work cycle. For example, if the welder has
a 60% duty cycle at 140A this means you can run the welder at 140A for 6 min in a 10 min work cycle. The remaining 4
minutes will be needed to let the machine cool down. If the welding current decreases, the duty cycle will increase and
vice versa.
Do not operate over the recommended duty cycle of the welding machines or damage will occur to the machine that is
irreversible. When output exceeds the duty cycle limit, the temperature within the welding machine will rise and the
protective circuit will cut off the power source output. The power output will then resume operation only when the
equipment has cooled down to normal temperature.
Note: Continuous overload operation will damage the welding power source. In these cases, the damage is not
covered by warranty repair.
WARNING!
This machine produces an electromagnetic field during operation. This field may under some
circumstances interfere with active or passive medical implants. To reduce the risk of serious or fatal injury, we
recommend persons with medical implants to consult their physician and the medical implant manufacturer before
operating this machine.
