• Turn the input power OFF at the disconnect switch or fuse box before attempting to connect or disconnect input power lines, out- put cables or control cables.
•Only qualified personnel should perform this installation.
•Do not touch metal portions of the work clip when the welding power source is on.
•Do not attach the work clip to the wire feeder.
•Connect the work clip directly to the work, as close as possible to the welding arc.
•Turn power off at the welding power source before disconnecting the work clip from the work.
•Only use on power sources with open circuit voltages less than 110 VDC.
LOCATION
For best wire feeding performance, place the LN- 25™ PRO on a stable and dry surface. Keep the wire feeder in a vertical position. Do not operate the wire feeder on an angled surface of more than 15 degrees.
