Fixed Automatic MIG Guns

Tregaskiss® fixed automatic MIG guns are engineered for hard tooling applications requiring a simple, durable and repeatable MIG gun. Available in air- and water-cooled models ranging from 350 to 600 amps, these automatic torches can be configured with the same consumables as your Bernard® semi-automatic or Tregaskiss robotic MIG guns to simplify your inventory.

High-performance consumables plus the armored neck and body plus the simple internal connections equal a torch that is quick and easy for you to maintain for maximum uptime and throughput.

Cable Options | Hytrel® Polymer versus Steel Monocoil

Cutaway of steel monocoil cable showing internal cable, trigger leads and copper — Steel Monocoil Cable
(cutaway shown)

Cutaway of Hytrel polymer (industrial grade) cable showing Hytrel inner tube, trigger leads and copper — Hytrel® Polymer Cable
(cutaway shown)

Hyrel® polymer or steel monocoil cable. What is the difference between the two and which one should you choose? The key difference between the two cables is the material of the inner tube at the center of the cable through which the gun liner, wire and shielding gas travels.

Bernard S-Gun™ is built with steel monocoil cable, which offers extra structural integrity to the cable. Users in industries or welding applications that require longer gun cables that are frequently looped or stretched around corners to the point of pinching are the ones who should consider upgrading their welding guns to our specialty steel monocoil cable.

For our welding gun users who do not experience these issues, Bernard BTB MIG guns are a great solution that offer long, dependable product performance with our heavy-duty Hytrel polymer cable.

Common Consumables Platform

Tough yet flexible!

The Common Consumables Platform™ means less consumable inventory is needed to maximize flexibility and productivity across a variety of MIG welding applications.

Durable, long-lasting Bernard® and Tregaskiss® consumables are designed for maximum flexibility and compatibility between a variety of consumable parts, gun models, and welding applications.

AccuLock™ Consumables

Bernard AccuLock™ S and Tregaskiss AccuLock R consumables share a common contact tip. If you have a combination of Tregaskiss robotic, fixed automatic and Bernard semi-automatic MIG guns in your facility, you’ll benefit from the reduced costs and simplified inventory of a Common Consumable Platform.

LOAD and LOCK to reduce downtime, troubleshooting and rework. Contact your local sales representative for more information.

TOUGH LOCK^® Consumables

In most cases, the same Tregaskiss nozzles, TOUGH LOCK® contact tips and QUICK LOAD® liners can be used with Tregaskiss TOUGH GUN® robotic and fixed automatic MIG guns, and Bernard® BTB and TGX® semi-automatic MIG guns.

Double-Life MIG Gun System

Double the life of your BTB MIG Gun!

Our built-to-order MIG guns keep on welding in the harshest and most abusive environments. The innovative Double-life MIG gun system* from Bernard allows you to extend the life of your BTB semi-automatic air-cooled MIG gun equipped with a T Series or C Series straight handle.

How It Works

BTB MIG guns with T Series and C Series straight handles have identical front and back handles and internal connections. Once the front end of the cable becomes worn, simply flip-flop the neck and trigger from the front end of the gun with the power pin on the back.

Arrows indicate that front and back end components of a straight handle BTB MIG gun model can be swapped to take advantage of the double-life MIG gun system

This results in a newer front handle to work with and the worn handle and cable moves to the feeder end of the MIG gun, extending the life of your gun.

*The Double-life MIG gun system is not compatible with B Series curved, B Series small curved, O Series curved, O Series small curved, or T Series small straight handle styles, or to any handle style if the MIG gun is equipped with Bernard®, OXO™ or Euro power pin options.

Dual Taper Technology

We’ve added a second taper at the rear of our TOUGH LOCK® retaining heads feature a second taper at the rear, so there is one taper for the contact tip connection and a second for the neck.

Dual taper technology creates a more secure seat, preventing the contact tip and retaining head from loosening due to vibration.

Dual taper technology:

Locks your MIG gun from contact tip to the neck
Keeps your consumables running cooler
Improves electrical conductivity
Decreases your downtime
