is a method that involves a high speed of ionized gas that is being released from the mouth of a procurement. Plasma cutters cut metal using a plasma torch.

No doubt if you’ve been pondering purchasing a plasma cutter, you have a few questions about the operation and what some of the recommendations are for setting up a plasma. Precious little information is available that give rudimentary plasma settings for given thicknesses of metal. And very little information is out there on the different types of starts, or how they work. Maintenance information is almost zero as well.

One reason for this is that plasma cutting is a skill that is quickly mastered. With a simple point, pull trigger, and go operation, it takes nothing more than practice and a fairly steady hand. There are a few items like guides, and hole cutters that you can add to your arsenal to help multiply the versatility and accuracy of your cutter. But these items are icing on the cake and can be picked up later, after basic skills are acquired. There are also a few “hidden” bits of information that should be covered if you are to be ahead of the game.

Over the next few blogs, will break down the small tidbits of information that you’ll need to make a plasma cutting success. You’ll become familiar with what a dryer is, where it should be used, the different start types, and how each can benefit , and even a few simple guides for setting up your plasma for the first cuts.

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 Tokentools 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-welding-tips are useful reminders intended to stress the main characteristics of Plasma Arc Welding (PAW) for the correct exploitation of its specific advantages.

The first of the Plasma-welding-tips is a correct definition of PAW, useful for understanding the differences that make the process unique.

Plasma Arc Welding is defined as a gas shielded arc welding process where the heat for welding is generated by an arc producing collimated plasma by the passage of the shielding gas through a constricting nozzle.

The copper alloy nozzle is called constricting because it presents a limited diameter orifice, through which the shielding gas, highly ionized by its transit through the arc, must pass.

The concentrated and collimated jet stream of ionized gas (composed of nearly equal number of electrons and ions of gas atoms and molecules) that exits at very high temperature (about 17,000 0C or 30,000 0F) from the constricting nozzle is called a plasma column.

Plasma Arc Welding can be performed with or without additional filler metal. In manual applications, the filler metal as added as needed by hand. In the mechanized version, the filler metal is added from the side by a wire feeder.

Plasma-welding-tips concerns understanding the specific features of the process detailed below, and using its capabilities for obtaining successful welding results.

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.
