How does a plasma down draft table work

How does a plasma down draft table work?

Why down draft?

Down draft tables are commonly used under plasma and laser cutting machines as an effective method for smoke collection and removal. Small down draft tables are common in shops where a work cell includes a hand-held plasma cutter. But larger CNC plasma machines and large plate lasers also use down draft tables on a much larger scale.


What Eye Protection Is Required for CNC Plasma Cutting

Don’t stare at the bright light!

A plasma cutting arc, like any electric arc, gives off a broad spectrum of electromagnetic radiation, which extends all the way from Infrared light (IR), through the visible spectrum, and into the Ultra Violet (UV) range. Plasma cutting arcs can also be very intense, because the arc current is typically anywhere from 100 to 800 Amperes. Needless to say, looking at an arc that intense can easily cause eye damage, including permanent damage leading to blindness.


Does Plasma Cutting Produce Hex Chrome

Does Plasma Cutting Produce Hex Chrome?

What is Hexavalent Chromium?

Hexavalent Chromium, also known as “Hex Chrome”, or Chromium 6, or Chromium (VI), is a heavy metal that is known to be a potent carcinogen when inhaled. It can occur naturally, but can also be generated by various industrial processes.

Chromium is found in the environment in two principal forms: trivalent chromium (chromium 3) and hexavalent chromium (chromium 6). Chromium 3 is found naturally in foods at low levels and is an essential human dietary nutrient. Chromium 6 is the more-toxic form of chromium.


What Is The Best Plasma Torch Coolant

What is the best plasma torch coolant?

Why does a plasma torch need coolant?

Every plasma cutting system uses some sort of fluid to cool the torch, and prevent the electrode and nozzle from melting due to the high temperature of the plasma arc. On smaller torches, typically anything up to 100 Amps, that fluid can be air, and it can be the same air that is used as the plasma gas. But as the current gets higher, a separate cooling liquid is required to carry away all of the heat.
