ALPHABETICAL LIST OF WORDS RELATING TO THIS MANUAL

Duty cycle

 

The duty cycle is the percentage of 10 minutes that the machine can  

 

 

weld for at a set amperage (10%=1min up to 100%=10mins). The higher  

 

 

the amperage, the lower the welding time.

Polarity

 

The relative orientation of electric poles.
