Pulse welding focuses the arc and makes the weld path smaller, so it stays in place. It's not only easier to control, but you still have full penetration. The puddle freezes as you enter the basic amp portion of the pulse cycle, and the cooling at that moment helps the weld to level out. The longer you spend on the background amplifier, the better the "puddle freeze" effect, which is what creates the appearance of a stacked dime. Pulse welding also completely eliminates spatter, so you don't have to do any post-weld cleanup.   When should we pulse weld? ❉ Stainless steel, aluminum and other highly thermally conductive metals Pulse not only helps prevent sheet metal distortion, but is often used with known heat sink metals. Cooler welds provide all the penetration needed without exploding the metal with excessive heat. ❉ Misalignment Welding The cooling of the puddle makes it smaller meaning it is less likely to drip. If you weld misaligned, the use of pulses will keep...

Pulse welding is a form of welding in which the amperage alternates between high and low points. It keeps the overall heat input to the weld low, while still achieving the proper depth of melt. Its pulse frequency, what the peak amperage is, what the base amperage is, and how long it spends at either amperage setting can all be adjusted to fit the weld you are making.   Pulse Percentage (%) The pulse percentage is the amount of time each pulse spends in peak and base amperage. If you set the percentage to 50%, this means that 50% of the pulse period will be peak amperage and 50% of the pulse will be base amperage. You can adjust this either way, where 90% is almost entirely peak amps and 20% is almost no peak amps. The more time you spend on the peak amp portion of the pulse, the more penetration you will get, and vice versa.   Pulse Frequency/Pulse Hertz Pulse frequency or pulse hertz is the same thing: the number of pulses per second. For example, UNIMIG AC/DC machines have ...

Typical plasma cutting machine air pressure ranges from 4-8 SCFM with a pressure of 90-120 PSI. this article details the air pressure requirements for plasma cutting machines and some of the conditions necessary to keep the system stable.   What is the air pressure for a plasma cutter? A plasma cutter is really the best tool for your shop. It helps in cutting different metals of various shapes quickly. The basic requirement of a plasma cutter is compressed air. The plasma cutter air pressure gauge provides you with an accurate reading to set the air pressure. Plasma cutters are very similar to electric welding.  A superheated arc heats the compressed air of the system to a point where it transforms into plasma. Usually, a starting arc is required to create the plasma. To be precise, the air pressure required for a plasma cutter is about 4-8 SCFM at 90-120 PSI. This plasma cutter air pressure is a generalization for cutting steel between 3/8" and 7/8" thick.    Some o...
