Additional Features

The LN9 and LN9 GMA semiautomatic wire feeders provide dependable performance and reliable operation, making them ideal for shop or field operations. For precise wire feeding and quality welds, these wire feeders feature controlled wire feed speed and voltage during starting for clean, positive starts and reduced stubbing, skipping and spatter. Solid state control compensates for wire drag and input line variations to maintain accurate wire feed speed.


  • Completely enclosed case – Protects the heavy duty wire drive mechanism from damage, yet allows easy access to drive rolls
  • Rugged and durable design - Recognized throughout the industry for its long life and years of trouble-free wire feeding
  • Standard digital meter - Can be set to read volts, inches or meters/minute on the LN9
  • Control of wire feed speed and voltage at the wire feeder - Eliminates the need to return to the power source to adjust procedures
