Safety Depends on You
Lincoln arc welding and cutting
equipment is designed and built with
safety in mind. However, your overall
safety can be increased by proper
installation ... and thoughtful opera-
tion on your part.
And,
most importantly, think before you
act and be careful.

Page 3: Electric Shock Can Kill
ELECTRIC SHOCK can kill. 3.a. The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands. - Page 4 WELDING and CUTTING SPARKS can cause fire or explosion. 6.a. Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding materials from welding can easily go through small cracks and openings to adjacent areas.

Page 16: General Description
GENERAL DESCRIPTION The LN-15 is a light weight, portable, durable semi- automatic wire feeder. The LN-15 accommodates spools 8" (200mm) diame- ter up to 4" (100mm) wide. The domestic feeders comes factory equipped with a K1500-2 Magnum Tweco-compatible style #2-#4 gun bushing. -
Page 17: Case Front Controls
CASE FRONT CONTROLS (See Figure B.1) ACROSS THE ARC MODEL 1. WIRE FEED SPEED DISPLAY-The Wire Feed Speed display shows the rate the LN-15 will feed electrode dur- ing welding. The default WFS units for domestic models are inches/minute and can be changed to meters/minute through the configuration menu. -
Page 18: Ln-15 Power-Up Sequence
LN-15 POWER-UP SEQUENCE Normal Power-Up Display When power is first applied to the LN-15, the display will momentarily show set-up information. For exam- ple, it may show "CV" and "HI", indicating operation from a CV power source and the wire drive is config- ured for the high speed gear. -
Page 19: Internal Controls
Rotate the WFS knob until the desired parameter is displayed. CV/CC Mode: WFS Units: 2. Activate and release the GAS PURGE switch to select the parameter. The present value will then display in the right hand side of the display. Example: 3. -
