I have noticed that when cutting with a T45m machine torch, it sometimes makes a crackling sound which can be heard over the hissing sound of the air flow. It is not very loud, but it is audible, and one can hear it if you listen carefully. Is this an indication of something faulty, or an early warning of something going wrong, or nothing to worry about? I cut thin mild steel, from 1 to 3 mm thick (about 19 to 11 gauge).

Re: Crackling sound made by Powermax45 machine torch
The crackling sound with the 45 comes from the Power Supply, and is an audible noise that comes from the inverter power supply. Many can hear this noise, many cannot (I have never heard it...even when standing next to people than can hear it). It is 100% normal with a Powermax45, and has to do with the inverter switching frequency. Jim Colt

Hi Jim,
Interesting that it comes from the Power Supply. To me, it sounds like it is coming from the torch! Anyway, I'm relieved that it is normal and not an indication of a problem!
Thanks very much and best wishes,

Make sure you don't have moisture or oil in the lines. The inverter noise is hard to hear when the machine is at idle. Not sure if your going to hear it when the air is flowing.

Thank you john78,
The thought of water or oil in the line also crossed my mind. But I do have water and oil filters, which I check daily.
