Never thought about that! An air supply full of water would be big problem! Interesting discussion here.

Anyone using a compressor with air tools, blasting cabinets and such should already have a good moisture management system in place. I don't have a dedicated dryer in line. I have a 60 ft run of black iron pipe along the ceiling for cooling with 3 drop t's and ball valve drains every 20 ft along with the ball drain at the bottom of the tank. With regular maintenance, the air out the end of the hose is usually as a dry as a pop-corn fart...

Randy can you post a pic of the two tips so we can see the difference...The ones that came with the cutter are concave ,I guess so the center of the tip dont actually touch the workpiece but the edge will make contact to get everything started...

old torchmate ?

Next you will want a pattern cutter, I made one about 15 years ago like the ones advertized 30 + years ago for my ox-acety system . I used a ford windshield wiper motor that i made a longer knurled shaft, then used a vary-ac controller and an older battery charger. Rotten leonard now sells a kit for a plasma , but manually move it.

I gota great air supply...One thing I noticed that got me thinking was where the air goes into he unit it says "gas" ,I remember being at the metal fabricators, where I get my materials from and they were cutting with the cnc plasma cutter and they were using Oxygen ,it got me thinking what would happen if I were to use oxygen insted of air or if its even an option for someone that dosent have dry air...

I think you would have a very big fire! Is not one of the biggest causes of house fires caused by smokers who are using medical oxygen?

Pure oxygen might make the flame point hotter ??? Don't know why they would use gas with a flame cutter. Like John said anything flammable would be a hazard...

Iam not fimilar with the new Plasma cutters but mine came with a dyer and a regulator attached to the rear of the unit and one on each outlet line and it has a automatic bleeder to help keep moisture to a minimum,,i guess it is the humidity out here but almost all compressors produce water =we drain 2 or 3 times a day when all the compressors are running,,it is probably dry enough on the left coast so you don't have to worry like we do out here

In Michigan we are surrounded by water on three sides, always humid and always draining water traps.
The water trap/regulator on the back of my plasma machine never gets water so I guess my air system takes care of the problem well.

The port that says Gas is used on the models of machines that also TIG weld. They use that port for shielding gas. As well as air.

I bought the lotos off of ebay a couple years ago and I love it. You may want to consider the pilot arc as it doesn't require the metal to be clean, it can blow through rust or paint but the consumable are much more expensive. I was able to easily cut a piece of rusty 1/2" steel in two, about a foot long and it made a really nice cut.
