Plasma cutting

A great tool for breaking metal structures or cutting something finer

A hot knife cuts butter … A hot plasma cutter cuts nearly anything in a similar fashion, if it even somehow conducts electricity. The plasma cutter is a great tool for breaking light or heavier metal structures or cutting something more accurate, but not too precise. The cutting seam is relatively clean, depending on the speed of the maker’s hand and its smoothness, tilt and distance to the piece … So if you have to do something neat and precise. Our plasma cutter needs compressed air as a friend (or shielding gas for extraordinary fine jobs). We have previously dismantled hot water boilers and steel structures from our customers premises. So cutting fast and quick, here and there is easy, but if you want to cut something precise, it would then require a manufacturing of some sort of a jig, which will be used to guide the cut along the way.

The cutting capacity goes somewhere around 25mm (we had not yet met so thick things to cut that we wouldn’t have gone through it). Compared to oxyasetylene cutting, plasma cutting is suitable for all materials that conduct electricity. Oxyasetylene (oxygen + acetylene) only works mainly on steel / iron. Oxyasetylene also carries its own risks associated with explosive gas and the work expels significantly more sud. In plasma cutting, smoke formation typically occurs about 3mm from the smoldering paint on either side of the cut groove, if any. The hardware is also considerably lighter than the gas equipment. The downside to plasma is its dependence on electricity and when making thicker cuts, the device really does require all the 16A from the outlet (and probably still blow a fuse from the electrical cabinet).
