welder is a semi-automatic gas shielded welder. To properly operate & maintain the
welder can assure it of good performance and prolong its operating life. Only the qualified personnel are
allowed to be in charge of repairing. It is strongly recommended customers contact with our company or

* Dust removal
The professional maintenance personnel should use dry compressed air (use air compressor or bellows) to
remove the dust inside the machine. The part adhering to grease must be cleaned with cloth while make sure
there are no loose parts ,the machine should be cleaned twice a year.
* Regularly check the input & output cables of welder.
*Don’t pull the feeder device by means of the torch cable.
* Use qualified wire.
* Clean the dust from liner with compressed air regularly (the dust is accumulated by friction between wire
and liner) to assure of even wire feeding.
* Please replace the feed roll if find it wear and tear to prevent wire uneven feeding.
ATTENTION:
* The welder voltage is always higher, so the safety precaution should be taken before repair to avoid
Accidental shock. Under no circumstance can anyone except the professionally trained personnel
open the case of the machine.
* Switch off the power source each time when removing dust.
* No touching inside cable or work piece while removing dust.
