Brand New Industrial Grade 3-in-1 Inverter TIG/MMA Welder, AIR Plasma Cutter Sale Price: $445.95 |
|
This auction is for a brand new 3-in-1 multi-functional welder. This welder is made with advanced inverter technology, and they have three functions: TIG/MMA/CUT. The inverter power is the power that first changes 50/60HZ working frequency to high frequency (as high as 100KHz) with high power factor V-MOS, and then reduces the voltage and rectifies, and then output with PWM the welding and cutting power of high power factor. By using the inverter technology of switch power, the weight and volume of the mains transformer greatly reduces, while the efficiency is raised by over 30%. When working as MMA or TIG, the outer characteristic is constant current and the welding current doesn't change with the length of the arc, the current is very stable. When working as CUT, the arc is compressed by the rapid-circulating air, and then its temperature reaches 10000-15000"C in the state of ionization, thus turning into strong plasma arc. The plasma arc into cutting makes the energy more concentrating, and gets smooth arc surface, which may take convenience for later work. This industrial grade welder can be widely used in welding and cutting carbon steel, stainless steel, alloy steel, copper and other nonferrous metals. It's portable, efficient, energy-saving and stable, and the exchange cycle of the assembled machinery can be as high as 85%. |

Here are some more information for Inverter Welder:

Wanna learn how to TIG weld aluminum?
First you need a decent TIG welding machine. Not a great one, just a decent one. Already got one? You might have an old Synrowave 300 or a DialArc, an old Hobart CyberTIG or you might have a brand new Miller Dynasty 350.
Know what? It doesn't really matter. The same principles apply. If you have an old as dirt TIG welding machine, you can still make good aluminum TIG welds. Weld beads that look like a stack of dimes.
First lets look at machine settings:
- Set the polarity to A/c (alternating currrent)
- Make sure to set the high frequency to continuous
- Set the amperage to about one and one half amps per one thousandths of inch of thickness. (up to about 250 amps then things change quite a bit)
- Set both the contactor and amperage switches to the remote positon.
- Set the argon or argon/helium torch shielding gas to around 15 cfh. (if you are using a #7 cup) less if the cup is smaller.
- Notice I said argon or argon/helium? Argon is not the only game in town. In fact, if you TIG weld any aluminum over about .063" thick, adding helium to the mix makes a huge difference.
Now lets talk tungsten electrodes
- 2% thoriated have received a lot of bad press for the radioactivity issue but they do work.
- 2% lanthanated electrodes are a really good all purpose electrode...good for TIG welding aluminum as well as steel.
- Use the smallest electrode that will get the job done without quivering at max amperage.
Remote amperage control...you need a foot pedal. Period.
- Once all the settings are ok, and assuming you are welding on 1/8" thick aluminum, grab a piece of 4043 filler rod in 3/32 diameter (rarely will you use a rod as thick or thicker than the metal you are welding)
- extend the electrode tip about 1/4" past the tip of the TIG torch cup and pre purge the gas by tapping the foot pedal.
- hold the torch like a big first grade pencil. touch the tip of the tungsten to the metal and then pull it back about 1/8 inch. flip your helmet down and press the pedal to initiate the arc.
- don't melt the aluminum right away though, watch the black stuff cook away from the arcs cleaning action before you melt the metal. Then press the pedal far enough to create a puddle that is about 3-4 times the thickness of the metal you are welding.
Now comes the part on how to achieve the "stack of dimes" look. You get that by adding the same amount of rod and by moving the torch the same distance each time you add rod. Add rod, Step ahead 1/8 inch,Add rod, Step ahead 1/8 inch,Add rod, Step ahead 1/8 inch, lather rinse repeat. If you do this consistently, you will get evenly spaced ripples that look like a stack of dimes.
Of course it looks different from underneath the welding helmet and it is harder than it sounds, but this is really how you do it. All that is left is the doing. It takes practice and lots of quality seat time.

Factors That Influence the Type of Used Welding Equipment to Buy
A simple search online will show you how vast and varied the offer for used welding equipment really easy; there are pictures of welding devices prior to reconditioning to reflect the amount of work as a guarantee for quality refurbishing as well as price comparisons between new and second hand devices. Most of the companies that sell such products offer advantageous warranties and even the option of returning the used welding equipment within thirty days in case you have any objections to its working quality. For those interested in the historic development of industrial technologies, technical museums usually have used welding equipment on display, reflecting the specificity of welding in time.
Before purchasing used welding equipment, a serious analysis of the business purpose is required so that you make sure that low costs are the most important issue at stake. There are several factors that should influence such a decision, but the most important ones worth talking about here are the utilization needs and the volume needs. For instance, you have to determine the utilization rate of the used welding equipment as well as the number of welders necessary to keep the business going. Last but not least the technological requirements are equally important for optimum functionality.
Most people who choose to buy used welding equipment are those who don't exploit it for too long a period of time; otherwise, if you have to utilize the welding devices at least in 70% of the activities, then, buying a new model is the more advantageous variant. Note the fact that high volume arc needs are also important when it comes to purchasing used welding equipment. You can use an inverter and an engine that performs both welding and power generation at the same time, and thus you'll cut off the expenses. Such a system is operated by a two-man team and requires professional certification.
For small working areas, special used welding equipments that incorporate 100 kw generators should be purchased to make sure that the maximum efficiency levels are achieved. In time, the analysis of the amortization rate in relation with the regular costs of the welding complex should provide a clear image of the profitability of your investment. It goes without saying that before purchasing any used welding equipments it is advisable to see all the technical peculiarities of the product and perform a professional check if possible. If you choose to buy used welding equipment on the Internet, see what kind of certifications and approvals the company that sells them has.

what is a welder inverter?
Do you mean welder/invertor.http://en.wikipedia.org/wiki/Welding_power_supply;;;;; check paragraph 6ish(same thing as rectifier.
Since the advent of high-power semiconductors such as the IGBT, it is now possible to build a switching power supply capable of coping with the high loads of arc welding. These are known as inverter welding units. These supplies generally convert utility power to high voltage and store this energy in a capacitor bank; a microprocessor controller then switches this energy into a second transformer as needed to produce the desired welding current. The frequency of switching is very high- typically at least 10,000 Hz and often much higher. Because of this high frequency, inverter-based welding machines can be much more efficient than transformer-based machines.
The actual IGBTs in an inverter based machine are controlled entirely in software, by a microcontroller, so the electrical characteristics of the welding power can be changed by software in real time updates. Typically the controller software will implement features such as pulsing the welding current, variable ratios and current densities through a welding cycle, variable frequencies, and automatic spot-welding; all of which would be prohibitively expensive in a transformer-based machine but require only program space in software-controlled inverter machine.
