Tired of seeing your broken bumper for a long time and not have enough time or money to go and get it fixed? No problems then! Here is a quick and easy way to do it!
So i am here to tell you about how to fix a bumper of your precious car. A car that might be your sole source of pride and that has to look good.
Getting a bumper changed or getting it repaired can be very costly and time consuming if you hand it over to the experts like a professional mechanic and the result may not come out to be as expected! To get out of this problem, follow the following steps to get done fast and easily.
Step 1: Take a sand paper of thick grains and make the surroundings of your bumper rough and hard i.e remove all the paint in the surroundings of the crack.
Step 2: Apply small glue on the bumper and place DRY cloth of fiber glass on the glued portion.
Step 3: Apply the fiber glass resin on the cloth and make it wet and leave it there for a couple of hours.
step 4: After it is dry, rough it again with the same sandpaper and apply the primer coat.
Step 5: Now sand it with a fine sandpaper and reapply the primer coat.
Step 6: Now apply at least 5 coats of desired color paint to the fiberglass part and the whole bumper, because it will look more homogenised.
And now, you are ready for the nice ride!
IGBT Plasma Cutters
IGBT Plasma Cutters
Plasma cutting in simple is a process through which steel and metal of different sizes and thickness is cut through the plasma torch. During this process, the inert gas or compress air used in some machines is blown at very high speed from the nozzle and at the same time electrical arc is made from the gas of nozzle to the surface needed to cut which turns some of the as to plasma. This plasma is suitably hot to easily melt the metal that is cut and it also moves fast to blow the metal far from the present cut. Additionally Longevity plasma arc cutters and several other applications also use IGBT plasma cutting technology which enables for Longevity to provide more commercial plasma cutting equipment.
The starting method
The Longevity IGBT plasma cutters generally use a different method to start the pilot arc and are built for professional metal working environments. Some IGBT plasma metal cutters might often use high frequency starting technology, high voltage circuit just for the starting process and others use Pilot Arc starting technology, where the torch enables a constant arc without touching the work piece. A Longevity IGBT plasma cutter featuring high frequency starting technology is more affordable, but also possesses a technological inferiority because of spark gap maintenance, difficulty of repair and you might also find a huge amount of radio frequency emission. Those plasma cutters which work near sensitive electronics like computers or CNC hardware would use the contact start method. The electrode and nozzle would be in contact. Here the nozzle would be the positive and electrode is the negative. So, when the plasma cutter gas starts to flow nozzle would be flown forward. However the other method which is less common is the capacity discharge in the main circuit through silicon controlled rectifier. In most cases Longevity uses Pilot Arc starting technology with IGBT Plasma Cutters because of the popularity and importance of a quick starting arc.
Inverter IGBT plasma cutters
The analog plasma cutter would generally need above 2 kilowatts and they also use heavy mains frequency transformer. The inverter plasma cutters generally rectify the main supply to the DC supply which is give as a high frequency transistor to nearly 200KHz. Some higher switching frequencies would give even greater efficiencies in transformer which allows its weight and size to be reduced.
The transistors that were commonly uses before were MOSFETs but today IGBT plasma cutters are highly being used in commercial or industrial applications where the demand of the size of the amperage is high. When placed parallel with MOSFETs and one transistor activates too early then, it can lead to cascading problem of one of the quarters of inverter. However with the newer invention and by using IGBTs, the Longevity Testing Team was able to avoid this problem. The IGBT plasma cutter can be commonly found in several high current plasma metal cutting machines that put out more than 60amps of power.
The Longevity ArcMate M200 IGBT Mig Welder is the first device to include IGBT technology in the Longevity Welding Equipment lineup, which achieved great success for MIG Welders able to compete with the leading brands and it enabled a it opened the doors for other IGBT welders and plasma cutters. After carefully testing a number of IGBT products by the Longevity Testing Team and well received recognition from welding professionals, it lead to the launch of the IGBT plasma cutters and welders full line up. These units are of top notch quality, are easily portable and can compete with any major brand that is today available in the market regarding both the price and quality.

Total confusion on wiring a 220-volt plug...?
None of the wire colors I have correspond 100% with any of the answers on here. I have a new MIG welder and a new 30amp plug that has to be put on it.
The plug has four terminals marked W, X, Y and G (green) for the ground. The cord from the welder has a black, red and a yellow (with green stripe) wires. No green ground wire as the portable welder has rubber feet. The question is simply how to connect red, black, yellow w/green stripe to X, Y & W?
No I'm sorry but the male plug which is what I'm trying to wire has four prongs marked as mentioned W, X, Y, G. The female is a portable Craftsman 5500W generator with an existing 220-volt outlet & 4 110-volt outlets which won't be used at the same time.
(w) white should be neutral, (g) green should be equipment ground, (x) and (y) should be the two ungrounded, or hot conductors, if you look at the plug it should make sense..
Did it make sense? you don't need the (W) terminal, so you use (X) and (Y) and (G) (G) is the equipment ground, sounds like this is a 4 wire twist lock,, take the plug apart and plug it into the generator and take a tester and you can see what terminals are the 240 volt if you can't see the letters there very good, the g should be easy to see.
If you have a 240 volt welder this should be fine, should be pretty easy to see after you look close..
Where's the Growth in MEMS in the Post-Recession Economy?
PITTSBURGH----MEMS growth continues to outpace nearly all other segments of the electronics industry, claim market researchers. The question is “why?” Executives from leading companies in the MEMS supply chain—Analog Devices, Applied Materials, Bosch Sensortec, Coventor and Kionix—say that continued acceptance of MEMS, or microelectromechanical systems, stems from a variety of reasons.
