Wire

Speed

listed

is a starting

value

only

Wire

Speed

setting can be

 

 

fine−tuned

while

welding.

Wire

Speed

also

depends on

other variables

 

 

such

as

stick

out,

travel

speed,

weld

angle,

cleanliness

of metal,

etc.

 

 

 

 

 

 

 

 

 

keep torch as

straight as possible.

A ”push

angle” for

the torch

is normally recommended.
