The Fire Triangle, And How It Relates To Oxy-Fuel Cutting

July 15, 2013

More than just an interesting discussion, studying the fire triangle helps understand how the oxy-fuel process works, which can aid in troubleshooting as well as proper operation. Studying examples of the fire triangle can also help machine operators and other factory workers recognize and avoid potential fire dangers and explosion hazards wherever they may exist.

How Does A Plasma Water Table Work?

July 7, 2013

When CNC plasma cutting, there are a lot of good reasons for using a water table instead of a dry, or down draft table. A water table is less expensive to purchase, does not require a dust collector (in most areas), reduces noise, eliminates dangerous arc flash, reduces heat distortion and keeps parts cool, just to name a few. And even though it is an older technology, a significant number of large gantry CNC plasma and oxy-fuel cutting machines are still sold with water tables.

How Does a Plasma Down Draft Table Work

June 30, 2013

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?

May 26, 2013

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?

May 12, 2013

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.
