Overload forbidden!
The operator must observe and check the maximum permitted charging current from time to time (depending on the
selected duty cycle) to ensure that the welding current does not exceed the maximum permitted charging current.
Current overload could significantly reduce the service life of the welding machine and even deteriorate it.
Meaning of the duty cycle: The percentage of the equipment running time in 10 minutes of service cycle, when the
welding current decreases, the duty cycle increases, when the welding current increases, it decreases.
When the welding machine exceeds the normal working cycle, it may enter protection and pause mode. The yellow
indicator on the front panel will glow. Under these circumstances, the power plug must not be disconnected (the fan
cooler must continue to operate normally to cool the welding machine). The yellow indicator goes off when the
temperature is back to normal. The machine can be restarted.
Warning
When the output exceeds the duty cycle level, the internal temperature of the equipment increases, at which point the
protection circuit operates and disconnects the power source output. The equipment will resume operation only after
cooling to normal temperature.
Note: A persistent overload could damage the welding power source.
Over-voltage forbidden!
The supply voltage is listed in the "Main Performance Parameter" table. In general, the automatic voltage compensation
circuit in the welding machine will ensure that the welding current is within the allowed range. When the power source
voltage exceeds the allowed value, the welding machine may be damaged. The operator must take this into account and
take the corresponding preventive measures.
3. Use of personal protective equipment
• The arc and its reflexive radiation damage unprotected eyes. Protect your eyes and face properly before starting or
observing the welding. In addition, please follow the different requirements of the darkness of the mask screen when
the welding current changes.
• Arc radiation and splashing could burn unprotected skin. Always wear gloves, protective clothing and footwear during
welding.
• Always wear the hearing protection if the ambient noise level exceeds the permitted limit (eg 85 dB (A)).
4. Other operating safety
• Be careful when handling heated solder parts. For example, the tip of the electrode support, the end of the welding rod
and the workpiece become hot, during the welding time, the elements can reach several hundred degrees, so there is a
risk of burns.
• Never wear the appliance on the shoulders during welding and never hang it by the carrying strap during welding.
• Avoid exposing the machine to high temperatures as this may cause damage to the machine.
• Keep the electrode support cable and the earthing cable as close as possible. Straighten the folded parts of the cables.
This action reduces exposure to dangerous magnetic fields that could interfere with a stimulator for example.
• Avoid wrapping cables around the body.
