1.  Environment 

1

  The machine can perform in environment where conditions are dry with a dampness level of max 90%. 

2

  Ambient temperature is between -10 to 40 degrees centigrade. 

3

  Avoid welding in sunshine or drippings. Do not let water enter the gas. 

4

  Avoid welding in dust area or the environment with corrosive gas. 

5

  Avoid gas welding in the environment with strong airflow. 

2.  Safety norms 

Our  welding  machine  has  installed  protection  circuit  of  over  voltage,  over  current  and  over  heat.  When  voltage, 

output  current  and  temperature  of  machine  are  exceeding  the  rate  standard,  welding  machine  will  stop  working 

automatically. Because that will be damage to welding machine, user must pay attention to following.   

1

 

The working area is adequately ventilated

 

Our welding machine is powerful machine, when it is being operated, it generated by high currents, and natural 

wind can’t be satisfied with machine cool demands. So there is a fan in inter-machine to cool down machine. 

Make sure the intake is not in block or covered, it is 0.3 meter from welding machine to objects of environment. 

User  should make  sure  the  working  area  is adequately  ventilated. It is important for  the performance  and the 

longevity of the machine.     

2

 

Do not over load

 

The  operator  should  remember  to  watch  the  max  duty  current  (Response  to  the  selected  duty  cycle).Keep 

welding current is not exceed max duty cycle current. Over-load current will damage and burn up machine. 

3

 

No over voltage

 

Power voltage can be found in diagram of main technical data. Automatic compensation circuit of voltage will 

assure that welding current keeps in allowable range. If power voltage is exceeding allowable range limited, it is 

damaged  to  components  of  machine.  The  operator  should  understand  this  situation  and  take  preventive 

measures. 

4

  There is a grounding screw behind welding machine, with a grounding marker on it. Before operation, welding 

crust must be grounded reliable with cable which section is over 6 square millimeter, in order to prevent from 

static electricity, and accidents because of electricity leaking. 

5

  If  welding  time  is  exceeded  duty  cycle  limited,  welding  machine  will  stop  working  for  protection.  Because 

machine  is  overheated,  temperature  control  switch  is  on  “ON’’  position  and  the  indicator  light  is  red.  In  this 

situation, you don’t have to pull the plug, in order to let the fan cool the machine. When the indicator light is off, 

and the temperature goes down to the standard range, it can weld again.
