Bernard® BTB MIG Guns with select Miller® packages will begin shipping on March 7, 2023 with a version of AccuLock that consists of a diffuser compatible with the common conventional style liners you are used to using, plus the added benefit of standard AccuLock S contact tips and nozzles.

AccuLock™ can transform the way businesses manage their MIG welding gun consumables — helping to optimize productivity, operating costs and welder confidence.

Less tip changes
Less welding troubleshooting
More beads worth bragging about

You will benefit from:

Longer Tip Life

Reduced contact tip replacement frequency
Contact tips are 60% buried within the diffuser for less exposure to the heat of the weld
Mating tapers on both tip-to-diffuser and diffuser-to-neck connection for good electrical conductivity
Shielding-gas cools contact tip tail
Less rework and ease of maintenance/replacement

Less Rework and Ease of Maintenance

Coarse thread contact tips speed tip replacement
Steel retaining ring on diffuser helps keep threaded nozzle in place during use/cleaning

AccuLock™ S Consumables with conventional rear-load liners are now available on select Miller® Packages including:

Upgrade to AccuLock S Dual-Locked Liners to receive all the benefits above plus:

Error-proof liner replacement, every time, with no measuring required!
Flawless wire feed path — AccuLock S front-load liners are locked and concentrically aligned to both the contact tip and the power pin, optimizing wire feeding, which eliminates welding liner misalignment gaps from your troubleshooting list

Yes! I want these AccuLock benefits!

Why offer conventional liners with AccuLock S consumables?

We’re offering conventional 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 conventional liner without retrimming. Later, when you want the additional benefits offered by the AccuLock S dual-locked 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.

Hercules MIG Welding Gun

Boldly Go Beyond the Welding Productivity You Thought Was Possible

The Tregaskiss Hercules MIG Welding Gun

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.

Hercules Product Manual

Includes installation, maintenance, troubleshooting and replacement parts information.

What is the Hercules System?

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.

AccuLock Consumables

Designed to address the key pains of our semi-automatic and automated MIG welding customers

Use the same AccuLock™ contact tips across your Bernard® semi-automatic and Tregaskiss® fixed automatic and robotic MIG guns.

Acculock S and R Consumable family share a common contact tip

Increase consumable life to decrease costs and increase productivity
Reduce consumables replacement errors to reduce troubleshooting, rework and downtime
Simplify consumables replacement to increase accuracy and reduce employee training requirements

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

Which AccuLock Consumables Are Right for Your Welding Operation?

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.

AccuLock S consumables family including contact tip, nozzle, diffuser, liner and power pin — AccuLock S Consumables

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:

Birdnests
Burnbacks
Erratic arc
Short contact tip lifespan
Excessive rework

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.

Learn More

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:

Frequent errors in selecting and installing replacement consumables
High inventory carrying costs
Pressure from Purchasing to reduce SKUs

If your primary welding challenges are specific to the different welding applications in your operation, we recommend that you use a mix of consumables:

AccuLock S consumables on your semi-automatic arcs
AccuLock R consumables on your robotic and fixed automatic MIG guns
The same AccuLock contact tips can be used on all your MIG guns

For issues specific to each application, please see the All Semi-Automatic Welding Arcs and All Automated Welding Arcs tabs.

AccuLock R consumables family including contact tips, nozzle and slip-on diffuser — AccuLock R Consumables

If you are experiencing the following welding challenges, we recommend using TOUGH LOCK™ nozzles, AccuLock R diffusers, QUICK LOAD liners and AccuLock contact tips:

Short contact tip lifespan – especially in pulse welding applications
Contact tip cross-threading issues
Excessive downtime for consumables replacement
Safety issues related to climbing up to access robots or wire feeders for gun liner changes

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.
