Beyond Commodity
The decision to switch to metal-cored wires involves much more than just a financial investment. Because they comprise only about 4 percent of the overall cost of a welding operation, filler metals often are perceived as a simple commodity. They have a per-unit cost and require ongoing...

Cool your torch
The difference is a matter of degrees. In an automobile, the heat source is the combustion chamber inside the engine, which operates at temperatures in excess of 2,000 degrees F. In a plasma torch, the heat source is the plasma chamber inside the torch, where the temperature of the arc can... Read more...
