The road transport equipment building industry is dependent on high quality welding machines and highly skilled welders to produce trailers and tankers of a standard that the market demands.
It’s for this reason, among others, that Welding Industries of Australia (WIA) offers the American-designed and built-to-last Miller Dynasty and Maxstar range of TIG Stick welding machines.
“Essentially, it comes down to quality – both in the product build and operational performance,” says Mathew Hefferan, Business Development Specialist at WIA, when asked what sets the Miller range apart from the competition.
“Every component used to build these machines is of the highest quality, which is why they produce such quality weld results and have a reputation among those who use them for being reliable and consistent.”
Mathew adds that a road tanker manufacturer that uses Miller TIG machines comments that they produce excellent results when welding the stainless-steel fittings that are integral to the builds.
“They describe the Miller machines as among the best on the market for achieving the consistent quality welds that are required for these expensive fittings,” he says.
The Miller TIG welding machines have a broad range of features including Auto-Line Power Management Technology – a key feature that’s exclusive to the Dynasty and Maxstar TIG Range.
This ensures smooth and consistent welding power with multi-voltage input, with the Auto-Line circuit boosting primary power to a higher and more constant voltage. Even if the incoming voltage varies widely, the circuit will ensure a rock-steady welding arc.
This feature provides a number of benefits including better weld quality from uninterrupted production, location flexibility, fewer amps, electrical efficiency and more welding output on the primary power.
“With Auto-Line, end users have the benefit of being able to use the welding machine in a workshop or out on a site with single- or three-phase input,” Mathew explains. “It’s also generator-compatible, so it can be used in remote areas where generator power is the only option.”
Other unique features of these welding machines include the wireless foot control which removes leads from the floor, ensuring a much safer working environment. Also, the TIG can run on either an air-cooled or liquid-cooled system.
Standout features of both Dynasty and Maxstar 210DX models include:
- Auto-Line technology – allows for any input voltage control (240-480v) with no manual linking
- Blue Lighting high frequency arc starter for non-contact arc initiation. This provides more consistent arc starts.
- Pulse – pulsing can increase puddle agitation, arc stability and travel speeds while reducing heat input and distortion.
- DIG control – allows the arc characteristics to be changed for specific applications and electrodes.
- Sleep timer – this conserves electricity by powering down the machine if it has been idle for a certain time.
- Stick-stuck – this detects if the electrode is stuck to the part and turns the welding output off to safely remove the electrode.
- Hot start – adaptive control provides positive arc starts without sticking.
- Fan-on-Demand – variable speed fan adjusts to match the cooling requirements.
- Wind tunnel technology – protects internal parts from airborne contaminants.
- Pro-Set technology – provides a starting point for new welders by giving them pre-set parameters and controls.
While the Arc and TIG welding machines share many features and are both considered premium products of their respective classes, they are suited to different applications.
The Dynasty 210DX is an AC/DC TIG welding machine that can weld aluminium. It is ideal for precision fabrication and maintenance jobs split between a workshop and site.
Meanwhile, the Maxstar 210DX is a DC TIG that is appropriate for welding exotic materials and steel, including stainless steel, copper and titanium.
The main differentiating feature that the Dynasty machine boasts – and one that is also exclusive to Miller – is its four AC wave formations. These are:
- Advanced squarewave – which provides fast freezing puddle, deep penetration and fast travel speeds.
- Soft squarewave – this enables a soft, buttery arc with maximum puddle control and good wetting action.
- Sine wave – is for customers who prefer a traditional arc with quiet and good wetting.
- Triangular wave – this reduces the heat input and is good on thin aluminium. It allows fast travel speeds.
As Mathew points out, these Miller welding machines are premium products that are widely considered to be the most advanced of their kind on the Australian market. They also have a reportedly unparalleled three-year warranty which includes parts and labour.
“Reliability is key,” Mathew reiterates. “We supply companies that are involved in defence-type contract work and we find they always come back to the Miller brand because it is reliable and consistent. Likewise, we have a lot of customers in the transport and automotive sectors and the features that these welding machines provide allow them to achieve quality weld results on a consistent basis.”
