Water vs Plasma

[jakeru]

I installed a small, inline "dessicant" filter in my air line on the back of the unit where the air goes in for plasma usage. Combined with ditching the shade 9 arc welding helmet lens (and using a more appropriate for plasma, shade 5) so I could actually see how far I'm holding the torch away from the surface, I immediately got much better plasma cutting results and longer consumable life.

I use 2, one cheap HF right at the compressor and the MotorGard on the plasma. Motorgard has the highest level of protection and the HF works as an inexpensive prefilter. Hopefully, the prefilter will extend the life of the expensive Motorgard unit.

Here is an easy way to maintain the right distance from the work for straight cuts.

Remove the wire standoff and use a piece of 1/4" aluminum as a guide. It fits into the notch formed by the cup and tip for the style of torch shown in the clip. This gives 1/16" gap between the work and the tip, perfect for a clean cut. A bigger gap makes for a sloppy cut, any closer is hard on the tip.
