Voltage can play a major part in the performance of any plasma torch. Why? It’s because a low voltage would not give enough power or electricity to the torch to burn plasma unless you lower your machine’s amp setting. This happens to me in this video and I want to share with you why sometimes there’s a case of a plasma cutter sputtering or a plasma cutter not arcing as we expected. The thing is this can be caused, most of the time by low voltage issues.

In this video, I was testing my new plasma cutter and was about to cut up a metal plate. However, the plasma cutter is not working fine as the arc just sputters and creates a rapidfire sound. So as part of my plasma cutter troubleshooting protocol, I changed the consumables in case they are malformed but still the plasma cutter is not arcing properly.

When I glanced at the amp the machine was set to and it was 55 amps and I thought there was nothing wrong with the amps. But then I remember my plasma cutter was hooked up to a transformer which was only 110 volts and that’s when I realized the plasma cutter was not working fine because of the low voltage source. The other day, I tested this new machine using my 110voltage transformer to see how things go when it’s using lowvoltage electricity and I forgot to put the plug back into my outlet which gives out 220240 volts.

So the lesson from this video is simple. In case of plasma cutter sputtering, there’s no need to consider doing serious plasma cutter troubleshooting. What you must do is check the voltage first then the amps that your machine is set to. But using your plasma cutter on low voltage is not actually a problem. All you have to do is turn down your amps so that the electricity that your machine gets is just enough to put up the right amount to create the plasma.

In this scenario, you will realize that when your voltage is only up to 110 volts, the maximum amp your machine can do is also only up to 35 amps while if your voltage is 220240 volts, you can set your machine up to 55 amps.

So the end of the story was when I plugged my plasma cutter back into my 220 volts outlet though the amps stayed at 55, the case of plasma cutter sputtering was gone. So if your plasma cutter is not working fine you should consider two possible causes first – voltage and amps and you might not need to think about doing plasma cutter troubleshooting as this can immediately solve the problem.
