are an important industrial tool used for cutting metals
such as stainless steel, aluminum, and other metals like brass in varying thickness. Plasma
equipments have been around for more than 50 years now, especially during the World War II when they were used for wielding joints in materials used for building aircrafts.
Later in the sixties, plasma cutting machinery became commercially viable and as a popular technique of cutting both ferrous and non-ferrous metals. The enormous benefits of speed and accuracy made possible through plasma cutters prove to be helpful for both heavy as well as small scale metal fabrication industry. And today, they are to be found almost in every nook and cranny, where metal works are done.
Many professionals who have experienced the convenience of using plasma cutting seldom wants use any other mechanical tools like saws, cutoff wheels, and shears.
There are many different types of plasma cutting
equipments available in the market such as portable plasma cutters
, plasma torches and plasma cutters
. Depending on the nature of your works, plasma
tools come in varying voltage or amperage. Portable plasma cutters are suitable primarily for cutting
sheet metal and other light work. If you are in a trade that involves a lot of wielding works, you probably need to get plasma cutters
for precision and quick execution of your metal crafting. The multi-purpose Longevity plasma cutter
model such as the WeldMex LC-416D
and WeldMex LC-518
can be used to automate your method of material fabrication. The various models of plasma
tools available with www.longevity-inc.ca may be a worthy deal as they are backed by an industry leading warranty besides the reasonable pricing. The first step to ensure smooth performance is to buy a machine that will be reliable for years.
Operating plasma cutters is easy. First you want to make sure you setup your plasma cutters properly including grounding, proper air pressure (depending on your model), and you have the proper power source to power the unit.
After reading the safety operations of plasma cutters, which can be found in the LONGEVITY plasma cutters resource pages, you are ready to begin cutting.
Things to do to insure a good cut:
- Measure the piece you are cutting twice before cutting to avoid any issues!
- Start cutting at full amps and turn down the amps as required to see what is the lowest setting you can achieve while still having enough power or amperage to penetrate your work piece.
- Check your pressure settings to make sure your air capressor is putting out enough air for a good arc. This various on the size you are cutting and the model you are using.
- Practice cutting a similar piece of metal (size, thickness) prior to cutting the actual workpiece.
- Go slow when cutting to insure that your arc penetrates the thickness of the metal,
- Maintain 1/8” distance between the workpiece and the cutting torch to prolong the consumable life and minimize slag from the workpiece.
- Brush off or chip off the slag that remains on the workpiece after you have completed the cut. Using a steel metal brush will help.
LONGEVITY also offers plasma cutters with built in TIG Welders and Stick Welders for just a little more. Check out our multi-purpose welders. If you are looking for MIG Welders, Stick Welders or TIG Welders, please look at our site for the best deals.
