Longer Tip Life
Less Rework and Ease of Maintenance
AccuLock™ S Consumables with conventional rear-load liners are now available on select Miller® Packages including:
We’re offering rear load liners with AccuLock S consumables to make it as easy as possible to convert existing fleets of BTB MIG Guns from Centerfire™ or TOUGH LOCK® to AccuLock S consumables. To convert your current guns from Centerfire or TOUGH LOCK to AccuLock consumables, simply swap out the nozzle, diffuser and contact tip. You can continue to use your existing rear load liner without retrimming. Later, when you want the additional benefits offered by the front load liner, you can upgrade your existing guns by swapping out the diffuser, liner and power pin cap or you can begin purchasing new guns with the full AccuLock S system.
Click here to download the AccuLock S Consumables Conversion Guide for Miller Packages. This detailed guide contains all the part numbers needed to convert your existing guns to AccuLock or to re-order the AccuLock consumables that came with your Miller package.
The Tregaskiss® Hercules™ Robotic MIG Gun is a key component of the Hercules system, an innovative single-arc solution that increases deposition rates by 30% or more without sacrificing weld quality or aesthetics.
Like other Tregaskiss products, the Hercules Robotic Gun is designed to maximize performance, longevity, accuracy, and ease of maintenance.
The Hercules™ single-wire, high-deposition, automated MIG welding system significantly boosts welding productivity rates without the expense of adding more weld cells. Only the Hercules system can deliver a gain of up to 30% or more in deposition rates and up to 30% or more in productivity with no loss of weld quality — making you more productive, competitive and profitable.
Developed by Miller, Hobart and Tregaskiss, the revolutionary Hercules MIG welding system combines Miller® power source and wire-feed technology, a unique Tregaskiss® torch and a specialized Hobart® metal-cored wire. Together, they boldly go beyond the welding productivity rates you thought were possible.
Eliminate welding bottlenecks, unlock unutilized capacity
With the Hercules System, welding will no longer be the bottleneck slowing your productivity. It unlocks capacity that’s currently underutilized, all without adding more weld cells — which require additional floor space or brick and mortar. In many cases, the Hercules MIG welding system doesn’t require all-new automation allowing you to use equipment that’s currently in place.
Improve welding throughput without risking weld quality
Compared to your current solid wire or metal-cored process, the Hercule MIG welding system can improve welding throughput 30% or more — all while delivering similar (or better) weld bead profiles, heat-affected zones and weld integrity.
Increase deposition rates by 30% or more
Get welding deposition rates that beat your current single-wire GMAW system by as much as 30% or more. Time and again, the Hercules MIG welding system delivers higher welding deposition rates than our customers thought possible — even customers who believed they were at the forefront of high-deposition welding with a “state of the art” system.

Use the same AccuLock™ contact tips across your Bernard® semi-automatic and Tregaskiss® fixed automatic and robotic MIG guns.
Choose from AccuLock consumable series options – AccuLock S and AccuLock R to achieve the above in the most effective way possible depending upon your mix of welding applications
Based on discussions with customers in key industries, we found that MIG gun consumables challenges differed depending on the quantity and mix of welding applications in each customer’s facility (i.e. semi-automatic, robotic, fixed automatic).
If you have all semi-automatic or automated arcs, the choice of AccuLock consumables is more straightforward. However, with the increasing adoption of automated welding to address the ongoing welder shortage, many operations now have a mix of welding application types. Click on the tab below that best describes your welding applications mix to learn more:
If you are experiencing the following welding challenges, we recommend using AccuLock S nozzles, diffusers, liners, power pins and power pin caps with AccuLock contact tips:
Many of the issues above can be traced to MIG gun liners that have been trimmed to an incorrect length or that pull out of position inside the MIG gun creating gaps along the wire feed path.
If your primary issues center around a complex and costly inventory of MIG gun consumables, we recommend that you use AccuLock R consumables as a Common Consumables Platform™ across all your semi-automatic, robotic and fixed automatic MIG guns. Issues typically experienced include:
If your primary welding challenges are specific to the different welding applications in your operation, we recommend that you use a mix of consumables:
For issues specific to each application, please see the All Semi-Automatic Welding Arcs and All Automated Welding Arcs tabs.
If you are experiencing the following welding challenges, we recommend using TOUGH LOCK™ nozzles, AccuLock R diffusers, QUICK LOAD liners and AccuLock contact tips:
Many of the contact tip issues above can be addressed by selecting from our AccuLock copper, chrome zirconium and HDP contact tips. Our front-loading QUICK LOAD liner system cuts liner replacement time in half and allows operators to access the robot from a safe zone in the robotic cell.
Bernard offers a wide range of fully configurable, industrial-duty semi-automatic air-cooled MIG welding guns designed specifically to accommodate a variety of welding styles, preferences and applications.
TOUGH GUN® clamps and mounting arms are made of tough yet resilient aluminum. These products are engineered to provide a robust and durable connection for the TOUGH GUN CA3 robotic air-cooled MIG gun.
The TOUGH GUN clutch clamp triggers an emergency stop in the event of a robotic collision and its new compact design allows for a larger working envelope. The TOUGH GUN solid mount clamp is available for clutchless models, offering the same increased working envelope.
Insulating discs help to protect your robotic investment by insulating robots and their controllers from the weld current, and are available with different bolt patterns for attaching TOUGH GUN robotic MIG guns to various brands of robots.
For applications where verification of tooling is a requirement, the TOUGH GUN neck checking fixture provides the opportunity to verify the accuracy of the neck to the intended tool center point (TCP). Further, an adjustment handle is provided to help implement minor adjustments if required.
Compatible with TOUGH GUN CA3 and legacy TOUGH GUN G1 series robotic air-cooled MIG guns, the original TOUGH GUN clutch is designed to e-stop your robot with a deflection of only 1° in the event of a robotic collision.
Made of high-strength aluminum, the TOUGH GUN solid arm mount can replace a clutch on TOUGH GUN CA3 and legacy TOUGH GUN G1 series systems using collision detection software.
Bernard and Tregaskiss offer a comprehensive selection of feeder connections for the most popular wire feeder models on the market. Select from the following:
Power pins provide a direct connection for wire, electrical current and gas flow between various wire feeder to MIG welding guns.
Quick-connect blocks and adaptors provide an adaptive bridge from your existing welding gun power pin to a different kind of feeder connection.
Control plugs transmit an on/off signal from the semi-automatic MIG gun trigger to the feeder as well as the dual schedule control (if equipped).
Bernard and Tregaskiss offer various rear load, innovative front load, and other revolutionary MIG welding liner solutions.
Load and Lock for Better Productivity
Load your liners from the front of the MIG gun in less than half the time it takes to install conventional liners.
Ideal for aluminum, steel, stainless steel and flux-cored wire, rear load liners are made of high carbon music wire for smooth wire feed and long life.
Genuine Bernard® and Tregaskiss® consumables enhance the performance of your MIG welding gun. They are manufactured to the same durable, high-performance standards as every MIG welding product we build, and they deliver the improved performance you’ve come to know and expect from us.
