Generation of the Plasma Arc (2 Ways):

Plasma cutters produce the plasma in one of two ways: High-Frequency (HF) Contact or Pilot Arcs. Which one your plasma cutter uses depends on how old it is; the new high tech equipments use pilot arcs. The major dissimilarity is that HF Contact models have to close a circuit with a work piece that conducts electrical energy in order to cut while the pilot arc models can cut anything. They work in very different ways.

HF contact method of generating plasma is still found in low financial plan plasma cutters and in older plasma cutters. How it works is the plasma cutting component is connected to the work piece by a clamp and wire and when you touch the nozzle of the torch to the work piece an electric circuit is created. An electric arc zips from the work piece threw the plasma torch nozzle to the negative electrode inside the torch head. At the same time, pressurized inert gas runs in the opposite way, from the torch head out onto the work piece. As the gas surges past the zapping electric arc it is heated to around 50,000 degrees Celsius. At that heat the gas becomes plasma which is a form of matter that is a liquid and a gas at the same time. It is this super hot, super fast moving plasma that cuts the metal. The HF contact technique is said to contain one cycle since the major plasma flow is created in one step.

The Pilot Arc technique is a two cycle procedure. First, a high power, low amperage circuit is used to make a small, high intensity flash in the body of the torch which creates a small pocket of plasma in the torch head (note that the plasma is previously produced in the torch without the required to touch the work piece, this is what eliminates the require for a conducting work piece). Now, you can use a trigger to ignite the main plasma arc that will be used for cutting whatever it is you desire to cut. Pilot Arc is the technique used in CNC plasma cutting applications.

Safety for MIG Welder:

Welding is a proven technique of permanently melding two metals together. Metal Inert Gas (MIG) welding is a world renown and appreciated trade, however, the risks can out method the rewards of its manufacture if the proper MIG Welder Safety guidelines are not taken. MIG Welder protection should be the main concern of the practitioner, novice or master, it should not matter what their ability level is, and the correct safety measures should always be taken.

Some ordinary guidelines of security may seem common sense enough but sometimes employers may push out these guidelines, don’t let them. Even if you are welding on your own, it is very significant to follow all of the MIG Welder Safety protection in order to enjoy a safe, creative experience. Some examples of safety precautions are:

Make sure that all of your skin is covered and protected from the powerful UV light that is created. Just close your eyes for a quick tack will not insure that you will not get arc eye. (Arc eye is an extremely painful result of improper exposure to the welding light. The feeling of pins and needles being positioned in the eye is an ordinary description.)

Always make sure that the area you are working in has an enough exhaust system in place. If you have problem with extraction, be sure to wear a breathing mask. Never have everything that is flammable wherever close to where you are working.

Never fail to remember the basic MIG welder security guidelines and never attempt to weld with no an instructor if you are not considered a professional.

The Best Diesel Generators - Everlast:

If you are interest in receiving something that is quite portable, then think a unit like Everlast Diesel Generators. In everlast having many models some of the models are DP15000EDS and DP18000ED. Both models weight is 1001 Lbs so it is not something you want to carry long distances but it is still portable and it will provide (DP15000EDS) Max AC Output: 15000W, Rated AC Output: 13500W and (DP18000ED) Max. AC Output: 18000W. Rated AC Output: 16500W of powers so you can get a lot of use out of it if you take this unit camping or to a remote place where you require using power tools. Both model dimension is 65"x29"x40" and Long 8-Hour Run Time at Full Rated Output. Long 12-Hour Run Time At 50% Rated Output.

If you desire to save some cash and still get a unit that is very functional, take a look at the DP6500ATS Diesel Generator. This is a Maximum Surge Output of 6500W diesel generator that is going to distribute ample power for most applications. It has some standard features like oil alerts, fuel gauge voltmeter, oil warning light, circuit breaker for protection etc. For smooth and quiet operation it is enclosed in steel frame which is very rigid and isolated by motor mounts. It has an air cooled diesel engine with 11.0HP. It includes full power panel with engine shut off switch, hour meter, voltage selector etc... The idle control feature of this generator saves fuel and reduces noise.

Some Points about Used Plasma Cutters:

1. Knowing the metal thickness that you will cut through earlier is actually helpful when shopping for a used plasma cutter. Knowing your preferred cutting speed is helpful as well. If you require cutting through 3/8" steel at 10 in/minute for example, you’ll find used Everlast plasma cutters very acceptable. If you need to cut through 3/8" steel at 75 in/minute, you will find a used Everlast PowerPlasma 50 plasma cutter satisfactory. Keep in mind that the thicker the metal, the slower the cut and this is true even with high capability cutters. Should you get into a conversation concerning ratings, remember that the normal rate is 10 in/minute.

2. Plasma cutter duty cycles point out a minutes per 10 minutes ratio of a rated capability. If you were to use a machine with a 70% duty cycle for instance, it could run at 400 amps for 6 minutes without having to be cooled. This information is critical when used plasma cutters function in hot surrounds.

3. When looking at your choices of used plasma cutters, make sure you can supply a stable stream of clean and dry air from an excellence air compressor. You will also require ensuring that any air compressor you use is able of satisfying an exacting cutter’s pressure necessities. Every cutter has a different requirement, so do not think that one air pressure is suitable for every cutter. You might find a small cutter with a built in air compressor, but if you are in the market for a big cutter, be ready to seek out an external compressor with a 40 - 60 PSI.

4. Portability is one more significant issue to address. In many cases, a cutter that sits idle for a while is not that big of a deal. A cutter that will be idle for a long time, such as during transportation for example, is a large deal as it can affect the machine’s unit delay.

5. Do not forget to verify that all controls are simply accessible and functioning. All analytic lights should work and consumables (including and air filter and dryer) must accompany the whole machine at either a very little fee or at no charge at all.

6. You will also desire to see if the product’s warranty is still in effect. This will help you get your used plasma cutter serviced. If you can locate the cutter’s producer, and that manufacturer is local and still in business that is even better.

7. Upon closer assessment, avoid buying a used plasma cutter that has broken cables, dirty inside compartments or other visual signs of spoil. These types of signs point out a very short life span and/or expensive repairs down the road.

Plasma Cutter Safety:

There are a little things regarding plasma cutter safety that are different from common welding safety tips. This small list of plasma cutter safety tips is geared toward light duty plasma cutting using compressed air not large manufacturing units that use gas mixtures and water cutting tables.

Electric Shock Can Kill:

- Operating a plasma cutter completes an electric circuit between the torch and the workpiece. The workpiece and something touching the workpiece are part of the electrical circuit.

- Never touch the torch body, workpiece or the water in a water table when the plasma system is working.

Voltages & Currents:

- Plasma cutter output voltages are large amount greater than welding voltages, usually 100-200 volts.

Precautionary Measures:

- Don’t pick up the workpiece, including the waste cutoff, as you cut. Leave the workpiece in place on the workbench with the work wire attached during the cutting process.

- During plasma cutting processes don’t move the work clamp.

- Wear insulated gloves and boots, and keep your body and clothing dry.

- Don’t stand, sit or lie on or if not touch any wet surface when using the plasma cutter system.

- Insulate yourself from work and ground using dry insulating mats or covers large sufficient to prevent any physical contact with the work or ground. If you must work in or near a damp area, use great caution.

The Advantages of Portable Diesel Generators:

* One of the main advantages of diesel generators is fuel efficiency. Generators with diesel consume less fuel than those that run on gas. Some diesel generators consume only partially their fuel load when functioning in the same capability as other generator types. This is why diesel generators are great for supplying nonstop power. They can therefore be relied upon to continually power refrigerators, computers and even house medical equipment.

* A portable diesel generator is sturdier than its complements. It can run for a total of more than 2000-3000 hours before you have to gravely think major maintenance work. You can simply see proof of diesel engine sturdiness just by looking at other equipment that runs on diesel. Heavy duty vehicles for example last longer than lesser ones used for transportation because they run on diesel.

* Normal maintenance is not a problem. This is because there are no spark plugs to maintain. You only have to keep in mind to regularly alter the oil and clean your unit from as often as the product manual tells you to.

* A diesel generator is ideal for rough terrain and rough work. These generators are many times more dependable in rugged environments than gas units. This makes diesel generators just right for offsite construction work and outside behavior.

* You will hardly have a problem with your fuel basis with a portable diesel generator. Diesel is http://www.blogger.com/img/blank.gifavailable in huge quantities almost anywhere. Just as long as a gas station is around, you are sure to locate some diesel supply.

* Diesel can be safely used in the majority instances. It is fewer flammable than other fuel sources. Diesel generators also do not contain spark plugs, which further lessens the chances of freak fires. You get immediate protection for both your property and your generator unit.

MIG Welding Safety Tips:

TIG welding torches:

There are lots of different models of TIG welding torches and if you get the incorrect one, it’s similar to buying shoes that don't fit...painful. So which TIG welding torch do you want? First of all, you need to come to a decision whether to go with air cooled or water cooled.

If you are a hobbyist welder, air cooled is the method to go. Why? For one thing, water coolers cost minimum $450 and air cooled TIG welding torches don’t need a water cooler. That's why.

Once you choose between an air cooled vs. water cooled torch, then you still contain some choices to make. Like whether to get a large TIG torch or a little one, a TIG welding torch with a gas valve built in or not including, a flex head vs. a rigid head, a 12 foot vs. or a 25 foot torch, etc.

Here is a list of proposals to guide you to buying the right TIG torch for your position:

• If you want portability, a 26 foot torch is the way to go.
• For portable circumstances that need fairly high amperage similar to aluminum TIG welding, the large style air cooled torches similar to a number 18 or 26 are in order.
• For little precise and low amperage circumstances, a little gas cooled torch like a WP serious works great.
• If you can afford it, a coolant re-circulator like an Everlast Cool mate opens up your choices and lets you use attractive much any TIG welding torch you want.
