how much less time will an inverter welder take?
Comments from an end user of a 350 for 2 years; tigger for 26 years, 10K hours on the bench. 70% repairs, 30% fab.
The driving reason behind a Dynasty 350 purchase needs to be time/labor savings, especially with AL welding. 6X faster than a tranny, as a guide.
The power and gas savings (from less arc-on time and gas lens) are the frosting on the cake.
The Miller Dynasty 350 allows for INFINITE tailoring of the arc characteristics in AC—for welding AL (Aluminum).
4 basic wave forms to choose from.
The arc can be focused to a tight, stiff cone about .060-.090 OD, then the amplitude of the waveform adjusted to vary the EP/EN to suit. The Electrode positive/Electrode negative amplitudes can be independent of each other.
Wave form balance is used, plus cranking the AC frequency up to stiffen the arc.
All of the above creates a powerful, intense arc that is much more efficient for precise, fast welding, penetration to suit and minimum heat input.
Massive, focused heat succeeds where all other methods-fail.
It's 6X faster than an old tranny, while consuming a fraction of the power and gas needed.
I began on a 400A Birdsell, then Lincoln idealarc 300/300, then new Lincoln 355 Squarewave, then on to inverters.
Most folks will just blow off the above buffet of basic settings as just so many bells and whistles to justify the ‘ridiculous overpricing’ of a damn welding machine. From a user experience that started with old transformers, then using my 4th machine-a thermal arc, 300 amp, AC-DC inverter in ‘97—I realized that one could weld 6X faster in AL than with a conventional transformer and could do things with that T-A that were impossible with the old units; plus (in my case—save a good, hard, real $2K/year or more in power savings and gas—which pays for the machine over and over).
Prior to purchase, I knew that learning the 350's computerized menu would be some work. I soon realized that everything I 'Knew' about setting up and running previous high power AC/DC inverters, squarewave trannies and conventional trannies--
---meant nothing when learning how to setup the 350. Using old set up techniques didn't produce the same arc characteristics. I was able to get 'okay' results, right off-first arc.....and then start the learning curve of the little details of 350 setups....just like every experienced user of the 350 has had to do.
Experienced AL tiggers know what they're looking for as they tailor the arc.
Low time AL tiggers-don't.
Collaborating with other users-helps. The link below shows the results of a setup method that's completely opposite to the 'norm'…….and works rather well for certain applications. Myself and others are still learning the potential of this machine.
Taking a different approach to independently adjustable EN and EP amperage.
