MIG Welding Guns

Here at HTP America® we make our replacement MIG welding guns to the highest standards—after all, these guns are OEM on our welding machines! We took the design principles employed in our own HTP guns and applied them to the replacement guns we build for other, non-HTP welders.

(Fig. 1).


A view into the construction of our replacement MIG welding guns enables you to see the quality of the guns. For instance, we use high temperature shrink tubing to prevent the trigger wires from chafing against the crimp connection (Fig. 1).

 

(Fig. 2).


Our crimp connection—the key to good transfer of the welding current— uses high-quality copper crimps and solid brass fittings and lock nuts (Fig. 2).

Looking at a cutaway of the coaxial cable (Fig. 3), you see the liner, which features a plastic coating to prevent the shielding gas from running out the back of the gun, that runs through the inner tube of the gun assembly. The shielding gas runs between the outside of the liner and the inside of the inner tube. The copper wires, which carry the welding current, and the trigger wires, which activate the machine, are neatly wound around the inner tube. Finally, we encase the whole assembly in a heat-resistant, flexible, rubber outer sheath

 

Where do air hoses typically fail? At the crimp connection where you go from a flexible connection to a rigid connection. That is why HTP guns use a spring support system at both the handle end and the machine end of the welding gun (Fig. 4 & Fig. 5).

Our color coordinated handles feature an ergonomic design that fits your hand better. Plus, you can disassemble the handle without any tools. If you really want to make welding easier, consider upgrading to an HTP flex neck MIG welding gun. We can outfit many of the guns we make with our flexible neck. The flex neck MIG welding gun works great for exhaust work or for building roll cages.

With an HTP replacement gun, you get the best of both worlds—a better than OEM quality gun at an affordable price! With over 40 years of experience in the welding industry, we can custom build you a gun for virtually any machine. So don’t throw that old welder away—put new life into it with an HTP replacement MIG welding gun!
