A lot has changed in Miller’s series of welders. Trailblazer 325, among other best-in-class models in the 300amps series, receives continuous updates year-in-year-out. And as expected, an upgrade may favor a side of the market. On the flip side, some other welder operators will find the same upgrade as a curse rather than a blessing to their ventures. An example of this situation is the 2015 update on the Eastwood 175amps TIG machine. The changed system drive and torch gun made the otherwise versatile unit an aluminum-only system for experts only. Therefore, in this Miller Trailblazer 325 review, we highlight everything about the latest version and show you what has changed so far. Let’s dive in.
In the previous version, all setups and configurations are done at the rear of the power supply. The only control you can make at a distance is heat frequency adjustment, either on a foot pedal or the gun torch. But on this new Miller Trailblazer 325 version, there’s an all-new ArcReach Technology on an external remote control. This technology replicates all setup functionality of the control knobs located on the power supply directly unto an intuitive remote control. Just soft click through the soft buttons to adjust amperage, frequency, and weld speed. All adjustment is sent over to the power source for faster adjustment response without the need for a connection cord between remote control and power supply.
Though this improvement may speed-up heavy-duty operations for experts and eliminate the need to walk the distance to the power supply for adjustment. It equally allows an entry-level unto welding for beginners and straightens out the learning curve. Another upside is the absence of obstructing connection cords stretched over a distance that may otherwise make movement difficult. Lastly, for auto repairers and assembly-line engineers, welding in tight positions such as under a car chassis just got easier and effective.
Talk about arc performance optimization. Trailblazer comes with a heightened amperage capacity that is truly 300amps as stated on the product’s specifications as listed on the manual. Coupled with an improved welding deposition, you can get the job done faster, increase productivity, and cut your power usage bill in half. Especially for TIG or STICK beginners, a more precise arc control is integrated. Basically an ultra-adaptive arc control technology, to allow fine-tuning the arc to your preference and minimize hits-and-misses. Regardless of your starting type, rub or scratch or high-frequency start, the improved feeder delivers accurate amperage to the work surface. Thereby, eliminating burn-through in thin gauges metal sheets. While allowing you to create deep weld pools between thicker materials more easily with minimized slags.
Weld Speed Automation
This feature is exclusive to Miller Trailblazer alone. An auto-speed technology that responds to current adjustment by matching the best welding speed to your configured welding current. This hasn’t been possible before. The oldest Trailblazer version, like most welders on the market today, retains the same weld speed through all welding current. For most, they come with weld speed adjustment which incur another setup work. Other welders maintain the same weld speed, thereby eating up your fuel and making unnecessary noise even when performing light-duty operations at low amperage. With the all-new auto-speed technology, you get a consistent 2500RPM of welding speed when welding at 150amps. This way, you eliminate unnecessary fuel usage, reduce fume emission, and perform silent, light-duty operations. Also, when you switch to 151amps or 210amps directly on your remote control. Or you do it from the control panel on your power supply. You are able to weld at a stable speed of 2800RPM. Likewise, when you adjust current between 211amps and 250amps for heavy-duty operations, a 3200RPM speed is automatically initiated to reduce operation cost and time. Finally, for your assemble line tasks on highly thick steel or aluminum, such as vehicle frame assembling. You get to speed up the process with 3600RPM welding speed by increasing welding current to 250amps. We believe this feature makes Miller Trailblazer a great fit for your garage to reduce power cost. In the same way, as you’ll be welding at low current with this welder at home, it’s a great way to save costs and avoid disturbing the neighborhood with a noisy unit. Overall, having such aspect as speed control taken care of by the machine itself, you can focus on delivering quality and professional welding service to your customers. Also, as a beginner/DIYer/hobbyist you can focus more on honing on your STICK welding skills with one less aspect to work around.
Optimized Power Generator Engine
Miller Trailblazer uses a new version of the Excel power generator technology to increase power output and optimize welding stability regardless of weld speed. While other models deliver auxiliary power at high-speed alone, the Excel technology engine delivers 2,400 watts of 120 voltages of inverter-based power on idle. Combined with the steady 25horse power, you take your STICK operation to the peak without burning through your fuel. In the same light, consistency is achieved on both high frequency and low-frequency arc. Likewise, the cable-free feature is an advantage to free movement on the field without interrupting power delivery or causing welding imperfection. Jobsite tools are uninterrupted for accuracy and cleaner welds, and thereby scaling productivity, quality, and stimulating profit. Speak about durability, the Excel engine is made to last to eliminate repair budgets. By the way, you don’t want to get stuck in-between an unfinished project and fixing a faulty welder. Your personal project at home may be postponed for another day but in the case of a customer’s work, you’d be losing credibility. Most importantly when working on a Jobsite or an assembly line.
You deserve more than just a welder when spending above 2grand on a metal-frying equipment. Right? The Miller Trailblazer’s generator is a dynamic power-shelling unit for multiple purpose. While it serves as a power supply for your welding ventures, it is also applicable in your battery charging business. You can power grinders and other Jobsite tools with the generator and even make it serve as an auxiliary power source to kick stubborn or dead engines back to life. This may open opportunities to mechanics and engineers in charge of a fleet of trucks, cars, and other lines of vehicles in the garage. The only thing you need to get separately is a 300422 jump/charge cables set to tap into this advantage. Get that available and you’ll put a steady 75amps-350amps power for battery charge and crank support to your advantage.
As a business welder operator, the least you could expect from a high price-point unit is to incur even more spending. Right? Exactly why an EFI option is included in this welder to reduce fuel usage by 42%. Yes, read that again. The EFI, the electronic fuel injection, as an option, complements the Excel power for a steady, pure-sine 21hours power supply on full tank. Just fill the 12 gallons tank capacity with treated gasoline. And you’ll be reducing refueling trips while preventing engine knocks traceable to the usage of untreated gasoline. The 1.5qtz oil capacity also cuts the numbers of oil replacements per month. This way, you save both gas cost and engine oil cost.
Portability; Less Transportation Hassle
While a heavy-duty piece of equipment is expected to be heavy of course, the portability of your welder has a lot of advantages to it. For one, a light-weight unit cuts away the expenses of moving a bulky welder over a short distance in a truck. Also, the ability to easily lift your power supply inverter when on a Jobsite or working down a construction assemble line is important. It speeds up your operation, saves stress, and allow you to utilize energy well. For this reason, unlike its predecessors, the updated Miller Trailblazer version sheds 10% of its weight away. Say goodbye to the heavy lifting.
On the same side, this new version is 17% less than its predecessor’s size. By implication, you get more space at the back of the truck to tag other essential pieces of equipment along for the fieldwork. Again, if you’re looking to save more space in your garage, home, or your auto repair shop, this may be a smart investment for your needs. The only downside is the absence of lifting handles that leaves the boys carrying it in a cart or in a bag. But who says you can’t weld tough handles unto the inverter body yourself?
Complete Duty Cycle
Remember where we mention the diversity of an upgrade? This is such an update on a welder that may be an improvement to a category of welder operators and at the same time a curse to other engineers. As a beginner, you’ll be needing more downtime to improve your welding skills at a pace with an FCAW welder. Unfortunately, Trailblazer 350 is a 100% duty cycle machine across all welding current levels. Meanwhile, for busy welder operators looking to put all their welding period to use, the 100% duty cycle of this unit is a plus. You can weld down the assembly line with no downtime, thereby spending less time and increasing productivity.
Attachments and Replacement Part
First off, the Miller Trailblazer will work with any 50amps 120/240V receptacle that has a circuit breaker in it. For a wireless connection to remote control, however, you can make a replacement with any 16-pins receptacles that have an auto-remote sensor built into it. Other replacement parts such as the LB model engine choke can be easily found at a low price. Meanwhile, for the protective transportation cage, Miller has one with off-road running gear with inner tubes. You can buy a complete accessory kit at Miller and it will include a 15-feet charging cable for car battery charging and heavy-duty protective bag that is mildew-resistant and waterproofed. Gas cylinder mounting accessory is also included in the kit.
If you have a follow-up on this series, you’d instantly notice a position change in the Trailblazer’s engine. It is now located on the front side for an efficient gas emission along with an expanded exhaust pipe. This new development allows efficient airflow and reduces the bulkiness of the previous versions. Also, since the exhaust pipe is now closer to the outside, the re circulation of emitted hot air/fume is avoided, which would have otherwise been detrimental to the welder operator’s health. Meanwhile, an inbuilt heating control in the inverter protects your investment from destructive voltage. And all delicate internal parts of the machine are cooled from overheating. Finally, an additional thickness on the inverter’s covering panels allows your welder to withstand more knocks especially for fieldwork. Overall, this is a safety-wise welding system for the money with no cable connections needed.
