Warning! Before using the welding machine read the instruction manual carefully! For qualified and specially trained persons only after proper reading of this manual is allowed to use and to maintain this welding machine

Environment to which the product is subject

• 
  The surrounding temperature range: When welding: -10 ~ +40°C During transport or in storage: -25 ~ +55°C
  
• 
  Relative humidity: when at 40°C : ≤50%, when at 20°C : ≤90%.
  
• 
  The dust, acid and erasable materials in the air can not exceed the amount required by the norm (apart from the emissions from the welder). No violent vibration at the job site.
  

• 
  There should be 50 cm space about for the welding machine to have good ventilation.
  
• 
  Keep from raining when it is used outdoors.
  
• 
  Please at a distance of 300mm or more from walls or similar that could restrict natural air flow for cooling.
  
• 
  The wind speed for all of the location should less then 1m/s;
  

The Requirement for Main Supply

• 
  input voltage from 150 to 240V
  

4. Installation

Installation welding machine

• 
  The dust, acid and erosible dirt in the air at the job site can not exceed the amount required by the norm.
  
• 
  The welder must be installed in the place where it can not be exposed to sun and rain. Also it must be stored in less humid place with the temperature range at -10 ~ 40°C.
  
• 
  There should be 50 cm space about for the welding machine to have good ventilation.
  
• 
  Apparatus to exclude wind and smoke should be equipped if the inside aeration is not sound.
  

Connection between Welder and Power Source

4. Operation

Attention:

• 
  The equipment class DC Inverter Arc Welder is class A. The class A equipment is not intended for use in residential locations where the electrical power is provided by the public low-voltage supply system.
  
• 
  DC Inverter Arc Welder adopt the drooping characteristic.
  
• 
  The 'protection indicator light' will be on after a long time operation, it shows that the inner temperature is over the permitted data, then the machine should be stopped using for some time to let it cool down. It can continue using after the 'protection indicator light' is off.
  
• 
  The power source should be switched off after the operation or while temporarily leaving job site.
  
• 
  Welders should dress canvas work cloth and wear welding mask to prevent the hurt from arc and thermal radiation.
  
• 
  Light separating screen should be put in the job site to prevent the arc will hurt other people.
  
• 
  Inflammable or explosive materials are prohibited to access the job site.
  
• 
  Each connection of the welder should be connected correctly and creditably.
  

1. 
   Connecting the power source switch, (Power Indicator Light) bright;
   
2. 
   Regulate the welding current potentiometer to reach the value for welding;
   
3. 
   Take-up the torch hand, aim at the welding seam, use the stick contact with the work piece and then the electric arc was ignited, i.e. you can effect the arc welding at the same time the (Welding Indicator Light) bright.
