OVERVIEW

Reliable Power and Comfort for All-Day Welding

If you are looking for a workhorse MIG gun that won't break the bank but still delivers the performance you need, the NT174 Bernard-style gun is the answer. Designed for welders who spend hours under the hood, this 400-amp torch combines heavy-duty power handling with an ergonomic design that helps fight fatigue. The curved handle fits naturally in your hand, and the trigger action is smooth and responsive, giving you precise control over your welds whether you are running long beads or tacking up a fit-up.

We know that downtime is the enemy, which is why this gun uses the industry-favorite Bernard Centerfire consumables. You won't be fumbling with threaded tiny tips; the drop-in tip design stays tight and conducts current better, meaning fewer burnbacks and less frustration. The 15-foot lead gives you plenty of room to move around your jig or table, so you aren't constantly dragging the feeder with you. Plus, the heavy-duty strain relief at the handle keeps the cable from kinking or pulling out, even when you're working in awkward positions.

This gun is set up with a Miller-style back end, so if you are running a Millermatic or a Miller feeder, it plugs right in—no tools or adapters required. It's built tough to handle the heat of 400 amps, making it perfect for spray transfer or running heavy flux-cored wires. Stop fighting with worn-out equipment and upgrade to a gun that works as hard as you do.

Why Welders Choose This Gun:

  • Comfort: Balanced handle design reduces wrist strain.
  • Reach: 15 feet of cable lets you weld where you need to.
  • Simplicity: Uses common parts you likely already have in the shop.
  • Durability: Tough outer jacket resists cuts and burns.
