Plasma Cutter & Plasma/AC-DC TIG/Stick (Inverter Design = Magic!)

[DivTec]

***HOPEFULLY I WON'T GET THUMPED BY THIS SITE OR IT'S MEMBERS BECAUSE I'M A SMALL BUSINESS OWNER SHARING THE BENEFITS OF INVERTER DESIGNED MACHINES FOR METALWORKING***

C'MON AMERICA... STOP YOUR PC ATTITUDE AND BUILD SOMETHING!

FEEL FREE TO ASK QUESTIONS ABOUT THE TECHNOLOGY AS I UNDERSTAND THE ELECTRONICS TO THE COMPONENT LEVEL... I'M AN OLD GUY LEFT OVER FROM A BYGONE ERA.

Every shop should have one of these machines, especially since they are so affordable. Let's see if you agree.

Machine Performance Thin & Thick Cuts:
(if you don't want to read... just WATCH and be AMAZED!)

PLASMA
50 amp plasma cutter, will cut thin sheet-metal (even painted) WITHOUT leaving heat-signature, no warping... to over 3/4 inch thick steel. Cuts all metals... and with a trick will cut glass, wood, rubber, even granite... not kidding! Plasma is very interesting! Only uses ~4.5CFM compressed air (about 2.5 HP compressor). Extremely efficient plasma torch... inexpensive consumables.
A very important feature is the ability of this machine to precisely shave levels (Z axis) of metal to a specific desired depth in a controlled fashion. Real project: Lawn tractor blade shaft, sprocket teeth rounded of. I used the stick to weld nubs, drew new blade pattern with marker, used plasma at low current to shave steel to proper depth following the pattern I drew previously. IT WORKED!

The hardness of metals is not a factor. This machine is just as happy cutting stainless, Inconel, etc. as it is with Aluminum, brass, copper, steel, etc.

AC-DT TIG
200 amp AC for aluminum welding, DC for steel, etc. Extremely precise welding on thin material with plenty of power for thick welds.
Controls for Gas pre-flow, Weld Penetration/Clean duty-cycle, Amp Output, Amp Decay Time, Gas Post-flow. AC Frequency (Weld bead width).
Dynamic current control is attached to the torch handle for very intuitive operation. (Can be easily fitted with common foot-pedal if desired.)
It is clear that all the "special" welding methodology typically needed for quality Aluminum welds do no apply to machine base on inverter technology due to the ability of the electronics to provide extremely fast polarity switching and extremely precise current regulation. As a best/worst case test we we're able to weld a soda can of 0.0035 inch thickness. That produced a WOW! It seemd like pouring Aluminum "resin" from a container... if that analogy makes sense.

AC-DC STICK
The stick welding mode on this machine is very interesting in ways that are not typical. Due to the inverter design Stick welding is much different on this machine than on a non-inverter. You can easily weld thin (I mean extremely thin) sheet metal with any rod size or type. Due to the extremely precise output current regulation, you can strike a arc, form a weld pool, and push around under command. No burn through or rod sticking. In fact as a test I have formed a weld pool... pushed the rod in until arc was extinguished... and the machine continued to put controlled heat into the weld which allowed the controlled forming of a metal tower. I'm not sure if what I did had application but, it did confirm the uniqueness of inverter welders to control output current and ultimately provide extremely good welds under worst case scenarios.

MACHINE INFO:
This machine is an Inverter design. This is very important due the inherent benefits.
Power in to power out efficiency is 85 - 87%... which translates into low input current draw of a maximum of 24 amp on 220 volt single phase... with enough current left over to run a small compressor. This means can be powered through over 150 ft extension cord of 12 gauge for extreme portability. The machine weighs ~45 lbs and small in size, adding to portability.

COMPANY INFO:
Small business, electronic equipment sales/service since 1975. Plasma cutter, welder sales/service since 2004.
We understand the electronics theory of operation of every circuit in every machine we sell. If repairs are needed, most problems can be solved by technical support by phone due to expertise.
If bench repair is needed we troubleshoot to the component level, no horribly expensive board replacement as with other brands. Feel free to check the cost of repairs for the "other" brands.
If you've been thinking about buying a plasma cutter and or welder... buy a machine that has it all.
Feel free to check out www.parkermetalworking.com
There you will find many machines, details, photos, video of machines in operation.
Be prepared to be amazed... then run, don't walk to the phone... and don't forget your wallet because the price is amazing too.

DivTec supply us a demo machine in late May when a bunch
of us are getting together and we will review it for you.

Put a wirefeed on it and give it MIG and FC capability and I'd be interested.

With inverter tech and electronic tech these days I'm surprised no one has made a "true" all in one machine that'll do all that plus AC and DC.

[WeekendWarrior]

eh, made in China, nevermind.

Ok... I'll give you a thrill... and tell you that your comment made me feel sad.

I know how you feel... but, you'd be selling yourself short out of stubbornness. I mean another way to look at it, is that you get to keep a hell of a lot more $ in your pocket... not mention that unfortunately no combo machines are made by US mfg's. WTF! I'm the closest you got, I import base machines (since 2004, do internet search) and technically embellish, cause I know how. And yet another bummer... can't find technical help these days. Hopefully, things will change in November. Go Mr. T!

This could make you feel better. I least the Chinese chose to us US designed Pulse Width Modulation chip. I mean great design... the workhorse. SG2535.
Turthfully, the machines that chose back in 2004 turned out to be an amazing design. Not sure if it's a copy or was designed by the Chinese. Really not anything but, properly designed classic inverter technology. They just did it right. I looked at two other designs back then, one was a technical embarrassment , the other was just mediocre.
The problem China has is quality of the build... as they let anyone build products, so quality varies. But, that's way we do, every machine we sell has been prepped. Very important!

This is partly why America is going down the tubes, we're giving our money to the Chinese.

I have a Lincoln 210 MP. It does stick, TIG, MIG and FC. Is that not a multi-process machine?

I agree about the addition of MIG function and it is a viable option. I have the circuitry designed and running on simulator... just one of many projects that are still on the shelf. However, if enough interest is expressed it could bubble to the surface as a priority.

Some specifics: MIG requires regulation of Load Voltage instead of instead of output current as with Plasma, TIG, and Stick welding.

Tell you what... any of you guys are welcome to come by my shop and demo until your heart's content.
Bring your worst case cutting/welding senerio (how the hell do you spell synerio?) and be prepared to be amazed. Roseburg, Oregon (Semi-retired on 10 acres... and love'n it. Hey, there's only so many re-runs a guy can watch.

Here's one that might create interest.
AC TIG, I successfully welded the tail end of a Coke can (0.0035"). That generated a WOW! It was felt like pouring Aluminum "resin" out of a bottle kind of feeling. Really quite interesting and proved to me from an electronics standpoint even more performance can be squeezed out of this design.
Some specifics: I had modified the polarity switching speed (originally opto-isolators we're used, which we're a bit slow). So I inserted push-pull buffers which improved repeatability along with the faster polarity transition speed. The current regulation circuitry was not modified and I was pushing the machine to provide the precise current regulation for that thin of a weld. The point is with appropriate mods to the current regulation, I think adding an "extreme precision" welding feature would be quite easy technically. Opinions please. How valuable would that feature be? Hmm.

BTW... I don't have problem substantiating what I say. I'm from the old days where it was common for a guy to say what he meant and mean what he say's.

Hope this stuff is interesting to you.
