    General Physical Description The LN-25™ IRONWORKER is specially engineered to be the most rugged portable wire feeder available and meets the individual welder needs. The plastic case is molded from a high impact, flame retardant plastic for durability and low weight. The patent pending design keeps the internal components protected and dry.

  • Page 20 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. POWER-UP SEQUENCE All of the LED’s 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.
  • Page 21 WIRE FEED SPEED UNITS To change the wire feed speed units: Rotate the WFS knob to left “inches/minute” for the wire feed speed units. O O WFS Rotate the WFS knob to right “meters/minute” for the wire feed speed units. Then rotate the WFS knob to the 12 o’clock position.
  • Page 22 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.
