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

***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.
