MMA SETUP

 

 

Output connections

 

 

Electrode polarity is generally determined by the type of welding rod being used although in general 
when using manual arc welding electrodes the electrode holder is connected to the positive terminal  
and the work return to the negative terminal. 

 

 

Generally, there are two connection methods of DC welder: DCEN and DCEP connection. 

 

 

DCEN: The welding electrode holder is connected to the negative polarity, and the workpiece is                

 

             connected to the positive polarity. 

 

 

DCEP: The electrode holder is connected to the positive polarity, and the workpiece is 

 

             connected to the negative polarity (as example shows below). 

 

 

The operator can choose DCEN based on the base metal and welding electrode. 

 

Generally speaking, DCEP is recommended for basic electrodes (i.e. electrode 

 

connected to the positive polarity).

 

 

Please Note:

 

Always consult the electrode manufacturer

’

s data sheet if you have 

 

any doubts.

 

 

 

 

 
 
 
 
 
 
 

MMA welding

 

 

1.

 

When connecting welding cables, ensure that the machines ON/OFF mains switch is                                            
turned off and never connect the machine to the mains supply with the panels removed.

 

2.

 

Insert the cable plug with electrode holder into the 

“+” 

socket on the front panel of the welding     

machine and tighten it clockwise.

 

3.

 

Insert the cable plug of the work return lead into the 

“

-

” 

socket on the front panel of the welding           

machine and tighten it clockwise.

 

 

If you want to use long secondary cables (Electrode holder cable and/or earth cable), you must ensure 
that the cross

-

sectional area of the cable is increased appropriately in order to reduce the voltage drop 

due to the cable length. 

 

 

Please Note:

 

Check these power connections 

 

daily to ensure they have not 

 

become loose otherwise 

 

arcing may occur when 

 

used under load.
