Magnum® PRO Curve™ 400 A Semiautomatic Welding Gun

  • Industrial Grade Construction
  • Lincoln Electric Copper Plus® Contact Tips:  Larger tip diameter and mass improve heat dissipation to increase tip life.
  • Curve™ Handle Design:  Our Curve™ handle is lightweight and balanced, providing a comfortable grip to reduce fatigue.
  • Rotating Gun Tube and Gun Hanger Clip:  Allow any number of hand positions to reduce fatigue or fit into tight spaces.
