Procedure
a)
Connect to the power switch digital ammeter lights on.
b)
To adjust the current potentiometer to the required value of the welding.
c)
Pick up electrode holder, and point at the welding edge. Then put the electrode on the workpiece,
you can start welding
Electrode Replacement
When the electrode is left only 2~3cm away from the holder, you have to replace new one to go on
working.
NOTES: When the electrodes combustion is in process at high heat, do not touch it with bare hands while
replacing it. Besides, the electrode head down should be unified in a metal container. And the cover
coating should not be caught by the holder. Scratch gently when igniting the arc, otherwise it is easy to
come across the phenomenon of sticking electrode.
Slag Removal
After finishing work, you should remove the slag with specific knock residue tools in the way of
knocking.
Warning!
The welding slag should not be removed until it is cooled down. Don't point it at the other people while
knocking on the slag incase that it will do harm with pop-up slag.
Maintenance
* The major difference between inverter arc welder and traditional welder is the inverter welder has lots
of advanced electronic components. What's more, it is high technology product. And this requires high
skill maintenance.
* It is very essential to do daily maintenance. You must be responsible for examination and repair. Once
you do not have the ability to check it, kindly contact with manufacturer to acquire the service and
support of technology.
The following is the steps for maintaining:
a)
Dust removal.
b)
Remove dust by professionals with dry and clean compressed air (using a compressor or Paper
Tiger) regularly. Meanwhile, check inter circuit of welding machine regularly and make sure the cable is
connected correctly and connectors are connected tightly. If scale and loose are found, please give a good
polish to them. Then connect them again tightly. Generally, if welding machine is operating in
environment where there is no heavy accumulated dust, the machine need remove dust once a year. If in
the environment where is polluted with smokes and polluted air, it is needed to be removed once or even
twice of each season.
c)
To maintain good contact with cable and plugs.
d)
Check up the contact conditions of cable and plug frequently, at least once a month for stationary
use.
Warning!
Due to high voltage in the main circuit of the welder, you need to do the safety precaution measure to
prevent accidental electric shock. Don't open the shell except for the professionals. Remember to turn off
the power before removing dust. And don't meddle with the connections and components when doing this
work.
