Plasma cutters
constitute a high-voltage electrical arc that slices over metal objects. The elevated heat from the electricity melts the metal as the torch moves along the surface. Plasma cutters are portable Sufficiently to be used in a inland workshop. They are powered by a sample 110-volt household ongoing and determine not demand any more tanks or fuel sources.
Instructions
1. Inspect the electrode and replace it if you see pockmarks or a deep pit in the surface. Pockmarks indicate a problem with the gas flow, while pitting means the coolant system is malfunctioning. If your plasma cutter is gas-cooled, low gas flow is the most likely cause of the pitting.
Plug in the plasma cutter and turn on the order breaker switch for the electrical outlet. Always use an electrical outlet with an operational third prong for grounding. Attach the plasma cutter's grounding clamp to your project to complete the electrical circuit.2. If you have a water-cooled plasma cutter, inspect the water line for kinks, leaks or clogs.
3. Replace the plasma cutter's nozzle if the hole in the tip is not a perfect circle. Use a stiff steel brush to clean the tip of the nozzle if you are not replacing it. Metal slag can build up over time and interfere with the electrical arc.
4. Check the air pressure settings if your plasma cutter will not maintain a steady torch. Set the pressure at the gas source approximately Thirty psi to Forty psi higher than the pressure on the plasma cutter. Turn off the unit and replace the gas line if the torch is still inconsistent. Make sure the line has a diameter of at least 3/8 inch so you have enough gas flow to generate the desired pressure.
5. Change the air filter on the regulator to keep all moisture out of the unit. Even small amounts of water can create internal arcs and damage the plasma cutter.
