What three types of power switches are used on plasma torches?

What three types of power switches are used on plasma torches? Thumb, foot (both manual), and automatic.

What is Torch coolant?

Torch coolant is a mixture of de-ionized water and ethylene or propylene glycol to depress the freezing point. Many shops use plain de-ionized water if there is no risk of freezing.

What temperature does a plasma torch cut at?

25,000 degrees Celsius
How hot does a Plasma Cutter get? The heat of a plasma cutter can reach an impressive temperature of 25,000 degrees Celsius. To put this into perspective, it is hotter than the surface of the sun which sits at a comfortable 5,505 degrees Celsius. Safety is paramount when using a plasma cutter.

What is the recommended distance the Pac torch nozzle should be above the base metal when cutting?

The shielding cup and constricting nozzle should be held approximately 1/8″ to 1/4″ above the metal being cut.

What happens to the plasma column when water is injected around the plasma stream?

Water Injected Plasma Cutting – this process uses a concentrated column of water surrounding the plasma column. The water column concentrates the plasma stream by increasing its swirl resulting in a higher density and increased temperature for faster mechanized cutting.

Do you need a air compressor for a plasma cutter?

All plasma manufacturers include minimum air flow and pressure requirements in the owner’s manual. If you do a lot of cutting, or plan to cut thick plate, we recommend using a compressor that is 1.5 to 2 times the plasma system requirement.

Can you heat metal with a plasma cutter?

No. Plasma cutters use a jet of air along with the arc to cut they pretty thoroughly oxidise the metal, plus the jet would just spray molten metal everywhere if you tried to contain it.

How is the temperature of a plasma torch cooled?

In a plasma torch the heat source is the plasma chamber inside the torch where the temperature of the arc can exceed 20,000°F. A plasma torch, like an engine, is cooled by a combination of radiation, convection, and conduction. Energy radiates from the arc in the form of intense ultraviolet rays.

What happens when a plasma arc cutting system overheats?

When the plasma system overheats it will also cost you time and money. An overheating plasma system will wear out torch parts quickly and eventually may burn out the torch and leads. If the problem goes uncorrected, a motor and pump may have to be replaced.

Can you use propylene glycol in a plasma torch?

Ethylene or propylene glycol is the same agent used in automotive cooling systems. However automotive antifreeze should never be used in a plasma system! Most commercial antifreeze has material in it to clog small leaks. This makes it unsuitable for use in a plasma torch.

What is the flow rate of a torch cooling system?

The individual components in the plasma cooling system are all designed to ensure one thing: an adequate volumetric flow rate to the torch for cooling. Flow is typically measured in gallons per minute (gpm) or liters per minute (lpm).
