1.

If “HIGH LINE” or “LOW LINE”

 

 

power. Welds are “cold”.

 

 

 

messages are displayed then

 

 

 

 

 

 

check the input voltage. Make

 

 

 

 

 

 

sure input voltage matches

 

 

 

 

 

 

nameplate rating and reconnect

 

 

 

 

 

 

panel configuration.

 

 

 

 

 

2.

Make sure settings for wire feed

 

 

 

 

 

 

speed and voltage are correct

 

 

 

 

 

 

for process being used.

 

 

 

 

 

3.

Make sure output polarity is cor-

 

 

 

 

 

 

rect for process being used.

 

 

 

 

 

4.

Check welding cables and gun

 

 

 

 

 

 

assembly for loose or faulty con-

 

 

 

 

 

 

nections.

 

 

 

 

 

 

 

 

 

Poor arc striking with electrode

 

 

1.

Make sure settings for wire

 

 

sticking or blasting off.

 

 

 

speed and voltage are correct

 

 

 

 

 

 

for process being used.

 

 

 

 

 

2.

The Run-In (Fast or Slow) speed

 

 

 

 

 

 

may be wrong for process and

 

 

 

 

 

 

technique being used. See
