USER MANUAL                                                                        - 3 -                                                                                  YF-68E/A0 

people with safety knowledge and technique to operate the machine. 

 

Danger! Please follow the rules below in case of electric shock:

   

Any contact of electric parts may cause fatal electric shock or burnt.   

1. Don’t touch any electric parts.   

2. Ask professional person to connect the machine and workpiece to the ground.   

3. Cut off the power box before the installation or checking, and restart after 5 minutes. For the 

capacitance is chargeable, please ensure it has no voltage before restart even if the power source is 

cut off.

   

4. Do not use cable without enough section or with worn-out cover or broken conductor. 

5. Do ensure insulation at the cable joint parts.   

6. Do not use the machine when the housing is off.   

7. Do not use broken or wet insulation gloves.   

8. Use safety net when work at high position.   

9. Check and maintain regularly, don’t use it until the broken parts are fixed well. 

10. Cut off all the input power when not use.   

11.  Follow  the  national  or  local  related  standard  and  regulations  when  using  the  AC/DC  machine  at 

narrow or high position.   

Danger!

 

Please use preventive measures to avoid gas and fumes.   

Gas and fumes are harmful to health.   

It may cause choke when operate in narrow space.   

1. In case of accidents like gas poisoning or choke, please use suggested exhaust equipment and 

breathe preventive facilities.   

2. In case of hurt and poisoning by gas and other powder, please use suggested part exhaust 

equipment and breathe preventive facilities.   

3. When operated on trunks, boilers, cabins etc.,the CO2 and argon gas will stay in the bottom. Please 

replace gas sufficiently and use gas respire facilities in case of oxygen shortage.     

4. Please accept the supervisor’s check when operate in narrow space, and ensure enough gas supply 

and use breathe preventive facilities.
