Connect the earthing clamp to the weldment. 

8. 

Insert into the electrode holder the appropriate electrode and you can start 
welding. 

 

NOTE

 

Prevent touching the electrode any metal material for in this mode 

the terminals 

C1

 and 

C2

 are under current.   

Insert the coated electrode into the electrode holder, connect the clamps of the 
ground cable to the welding piece and you may start welding.
