§4.5 Operation Environment
●
Height above sea level is below 1000m.
●
Operation temperature range:-10
0
C
～
+40
0
C.
●
Relative humidity is below 90 % (20
0
C).
●
Preferably site the machine some angles above the floor level, the maximum angle does not
exceed 15
0
.
●
Protect the machine against heavy rain or in hot circumstance against direct sunshine.
●
The content of dust, acid, corrosive gas in the surrounding air or substance can not exceed
normal standard.
●
Take care that there is sufficient ventilation during welding. There is at least 30cm free distance
between the machine and wall.
§4.6 Operation Notices
●
Read §1 carefully before attempting to use this equipment.
●
Connect the ground wire with the machine directly.
●
In case closing the power switch, no-load voltage may be exported. Do not touch the output
electrode with any part of your body.
●
Before operation, no concerned people should be left. Do not watch the arc in unprotected eyes.
●
Ensure good ventilation of the machine to improve duty ratio.
●
Turn off the engine when the operation finished to economize energy source.
●
When power switch shuts off protectively because of failure. Don’t restart it until problem is
resolved. Otherwise, the range of problem will be extended.
●
If there is any problem and has no the authorized professional maintenance personal of our
