§4.6 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.
