repairing, accessories supply and service back-up when they feel unable to work out the technical hitch or
problems.
• Maintenance job should be conducted by the trained personnel. It is never allowable to have hot line job.
• The newly installed welder or it not in use for some time needs to be surveyed the insulation resistances
between each winding and every winding to case with multimeter, which can not be less than 2.5MΩ.
• Keep from rain, snow and long term exposing to sunlight when welder is used outdoor.
• If the welder is not in use either for a long time or temporarily, it should be kept dry and have good ventila-
tion to free it from moisture, eroded or toxic gas. The tolerable temperature ranges from ﹣ 25 ～﹢55℃, and
the relative humidity can not be more than 90%.
• 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 loosing parts existed in the tightened places and connected cable. Usually the machine
should be cleaned once a year if the dust accumulation problem is not very serious, while it needs cleaning
once or even twice every quarter if the dust accumulation problem is serious.
• Regularly check the input & output cables of welder to guarantee them right and firmly connected and
avoid them being exposed. Check should be taken once every month when fixed using and every check
taken when removing.
• Regularly check the seal performance of gas system, whether the fan and feeder motor having abmodeal
sound and whether every joint being loose.
• Keep torch cable direct when welding.
• Regularly clean the splash of nozzle (cannot use the way similar to knocking the torch head) and stick to
using splash ointment. Don’t remove the feeder device by means of pulling the torch cable.
• Use qualified wire, no using inferior or rusty wire.
• Clean the dust of liner with compressed air after the welder using some time (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. The pressed roll can not
be pressed too firm to guarantee smooth wire feeding. (It will lead to wire deformation, adding the feeding
resistance and accelerating the friction of gear if pressed over firmly.)
ATTENTION
• The welder voltage is always higher, so the safety precaution should be taken before repair to avoid Ac-
cidental 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.
