Built for the Professional

The Tweco Classic 3 features a patented Cablehoz® design that resists cuts, abrasion, and heat, ensuring a long service life even in aggressive shop environments. The connection between the cable and the gun is reinforced to prevent cable pull-out, a common failure point in lesser torches. The 15-foot length offers excellent flexibility, allowing welders to move freely around large workpieces without constantly repositioning the feeder.

Consumable Compatibility

Maintenance is straightforward with the Classic No. 3. It utilizes the industry-standard Tweco consumable platform:

  • Contact Tips: 14 Series (Heavy Duty)
  • Nozzles: 24A Series (Adjustable)
  • Diffusers: 34A (Insulated)

This compatibility ensures that replacement parts are easy to find and affordable, keeping your operating costs low. Whether you are running flux-cored wire or solid wire on heavy steel, the Tweco 1030-1137 provides the arc stability and feeding reliability professional welders trust.
