Thermal Dynamics
An Introduction to Plasma Cutting
With Plasma Cutting, plasma gas is heated to an extremely high temperature and ionized so that it becomes electrically conductive. The metal to be cut or removed is melted by the heat of the arc then blown away. Plasma is used to transfer an electrical arc to the work piece. It creates a very clean dross free cut with minimal heat input, usually requiring very little re-work or cleanup.
Plasma is an excellent choice for most cutting applications but is particularly well suited for applications where speed and excellent cut quality are important. The plasma arc cuts ferrous and non-ferrous metals faster than oxyfuel or abrasive saws, with a minimal heat effected zone.
Safety
Before You Begin Cutting
Operation and maintenance of Plasma Arc Equipment can be dangerous. To prevent injury you should understand and follow safety precautions.
- Protect your ears from excessive noise levels.
- Protect your eyes with a welding helmet or shield.
- Always wear safety glasses with side shields, goggles, or other protective eyewear.
- Wear welding gloves and suitable clothing to protect your skin from the arc rays or sparks.
- A filter kit is recommended for improved filtering with compressed air to keep moisture and debris out of the torch.
1Torch with SureLok Technology
1Torch is the most innovative, reliable, high performance torch available today. The Thermal Dynamics 1Torch is easily adaptable to virtually all plasma cutting power supplies and lead extensions are available in 15, 25, 50 foot lengths.
Cuts
Drag Cuts
With the drag cut you actually drag the tip of the torch along the work piece to cut the metal.
Standoff Cutting
The stand off cut may be suitable when material thickness is 3/16th of an inch or greater. The torch is held so the tip remains 1/8th to 1/4th of an inch above the plate. Special devices such as stand off guides and cutting guides can make cutting easier.
Piercing
Piercing with plasma produces a quick hole through the plate and is recommended on thicknesses up to 50% of the cutting system's rating. Begin with a slightly longer arc length and slowly lower the torch, piercing the through the plate.
Straight Line Cutting
Our straight line cutting guide for hand held systems helps produce more efficient straight line cuts. The guide is secured on magnetic mounts or optional suction plates for aluminum and stainless steel. The guide can also be used to make bevel cuts.
Bevel Cuts
It is often easy to use a piece of square tubing or an angle iron as a guide. Or use the straight cutting attachment that can be angled for your bevel.
Gouging
Plasma gouging produces a very smooth, clean surface, which is often weld ready. It can also be used to separate two welds with less noise and less smoke than traditional gouging methods.
Using the Circle Guide
With proper attachments the circle cutting guide cuts circles from 2 1/4th to 27 3/4th inches.
