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.
