NOTES
When the welder works for a long time, the high temperature indicator will light. This means the inside temperature has
exceeded its standard. And you must turn off the power immediately for a period until it recovers.
• You have to wear canvas overalls and face mask to prevent from arc light and heat radiation.
• Vibration screen should be laid out to prevent others from arc light.
• Inflammable and explosive stuffs are not allowed to pile up. All the connections must be right, reliable.
5.1 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.
5.2 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.
5.3 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.
5.4 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
