Why is my Hypertherm plasma cutter not working?
Change out your nozzle and electrode as those two consumable parts are often the first to show signs of wear. If that still doesn’t fix the problem, try changing your swirl ring. Also, look at your air supply as moisture could be the culprit here as well.
Why does my plasma cutter keep shutting off?
Too slow of travel speed when cutting- Moving excessively slow when cutting (especially at higher amps) overheats the torch consumables and can cause the parts to wear out prematurely. It can also cause the arc to terminate.
Why is my plasma cutter overheating?
Travel speed too slow: A slow travel speed when cutting can also cause the torch consumables to overheat and wear out parts prematurely. Be sure to move the tool at a sufficient speed, particularly at higher amperage.
Why is my plasma cutter sputtering?
This is caused when the high frequency can’t penetrate the high-pressure barrier that exists between the electrode and nozzle. To correct this, double-check the factory-recommended settings for gas pressure and flow to ensure that the pressure is at the right level for optimal performance.
Why does a plasma cutter need to be grounded?
Good grounding practice is to connect the frame of the table to a separate ground rod located close to the table. The reason for this is cut down on noise generated by the plasma arc from affecting the motor and data cables on the table.
How long do plasma cutters last?
Usually, in normal conditions, we can say that the electrode will wear out first during machine cutting. Typical life time of a set of consumable should last about 1 to 3 hours for about 120 A of mechanized cutting, it’s in function of the job. Cutting at lower current may gets longer consumable life.
What is a common issue when plasma cutting?
Cutting too fast or too slow Cutting too fast or slow will cause cut quality problems. If the speed is too slow the cut pieces will develop “low speed dross,” a large bubbly accumulation of dross along the bottom edge. Slow speeds may also cause a widening of the kerf and excessive amounts of top spatter.
Can you get electrocuted by a plasma cutter?
However, plasma arc cutting requires higher voltages than welding to start and maintain the arc – typically 110 to 400 VDC – and touching live electrical parts can cause fatal shocks or severe burns. Poor connections and bare spots on cables increase the possibility of electrical shock.
