A Free copy of “Arc Welding Safety” booklet E205 is available from the Lincoln Electric Company, 22801 St. Clair Avenue, Cleveland, Ohio 44117-1199. BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES ARE PERFORMED ONLY BY QUALIFIED INDIVIDUALS.
- Page 3 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. 3.b. Insulate yourself from work and ground using dry insulation.
- Page 4 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. Avoid welding near hydraulic lines.

It is designed for industrial and professional use. All electrical equipment generates small amounts of electromagnetic emission. Electrical emission may be transmitted through power lines or radiated through space, similar to a radio transmitter.
- Page 7 The size of the surrounding area to be considered will depend on the structure of the building and other activities that are taking place. The surrounding area may extend beyond the boundaries of the premises. Welding equipment should be connected to the mains supply according to the manufacturer’s recommenda- tions.

ELECTRODE CONNECTION The LN-25™ PIPE (CCC) does not include the elec- trode cable. The customer is to install an AWG 2/0 to 4/0 cable. To install: 1. Turn off power at the welding power source. 2. With a 5/16” nut driver, remove the 4 screws hold- ing the rear cover panel. -
Page 18: Operation
SAFETY PRECAUTIONS READ AND UNDERSTAND ENTIRE SECTION BEFORE OPERATING MACHINE. WARNING • ELECTRIC SHOCK CAN KILL. Unless using COLD FEED fea- ture, when feeding with gun trig- ger, the electrode and drive mechanism are always electri- cally energized and could remain energized several sec- onds after the welding ceases.. -

The LN-25™ PIPE is specially engineered to be the most rugged portable wire feeder available and meets the individual welder needs. This model includes a gas solenoid for flexibility to run most wire processes. The plastic case is molded from a high impact, flame retardant plastic for durability and low weight. -

For best results, keep the gun cable and conduit as straight as possible. Perform regular maintenance and cleaning on the gun liner, conduit and gun. Always use quality electrode, such as L-50 or L-56 from Lincoln Electric. LN-25™ PIPE Maximum WFS... - Page 21 POWER-UP SEQUENCE All of the LEDʼs will briefly illuminate during power-up. If the gun trigger is activated during power up, the feeder will not operate until the gun trigger is released. WIRE FEED SPEED/AMPERAGE DISPLAY Idle The left display shows the preset wire feed speed. The right display shows OCV.
- Page 22 WIRE FEED SPEED UNITS To change the wire feed speed units: Rotate the WFS knob to the left to use “inches/minute” for the wire feed speed units. Rotate the WFS knob to the right to use “meters/minute” for the wire feed speed units. Then rotate the WFS knob to the 12 oʼclock position.
- Page 23 LEFT DISPLAY SELECTION The left display can show either amperage or actual WFS during welding. Note that actual WFS is not the same as preset WFS. For example, the preset WFS may be set to 400 ipm, but the arc voltage is only 15V. The actual WFS will be approximately 280 ipm because there is not enough arc voltage to run at 400 ipm.

If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, contact your Local Lincoln Authorized Field Service Facility for technical troubleshooting assistance before you proceed. - Page 33 3. Blow dirt out of the liner with low pressure (40psi or less). Replace the liner if worn. 4. Use only clean electrode. Use quality electrode, like L-50 or L-56 from Lincoln Electric. 5. Replace the contact tip. 6. Verify the proper parts are installed.
- Page 34 Observe all Safety Guidelines detailed throughout this manual PROBLEMS (SYMPTOMS) Wire feed speed consistently oper- ates at the wrong value. The speed changes when the wire feed speed knob is adjusted. The wire feed speed stuck at 200- 300 in/min and there is no change when the wire feed speed knob is adjusted.
