These are a few of the important details in regards to the Razorcut 45 Plasma Cutter. I have not found many details on what the expected life of its consumables are but the important details follow, including what I used to prepare my manspace for the table.
Question 1
It would be nice to know…
How long an electrode will last, how long a nozzle will last, how long the swirl ring lasts, and last but not least, how long a retaining cap lasts?
I know that these will fluctuate based on how dry your air is and some other use factors but averages would be great
Questions 2
Would it be better to go with the 3/64" orifice or the 1/16" if we are running at 40 Amps or greater? It would be a bummer to have to invest in two sets of nozzles but I understand the probability of a need to do so.

The tip orifices focus the plasma stream to the work piece. It is important to use the correct size tip for the amperage being used, for example a tip with a 3/64" orifice is good for 0-40 amps whereas a 1/16" orifice is better for 40-80 amps
Air Pressure and Volume
The required air pressure and volume can vary from model to model and the manufacturer will provide the specs. The RazorCut45 air pressure is pre-set at 4.5 psi and requires a flow rate of 6.0 CF/M. The volume capacity of your compressor is important, if you have a small compressor with exactly the same l/min rating as the plasma, then the compressor will run continuously when you are plasma cutting, a compressor with a l/min rating slightly higher than the plasma would be more adequate. If you are doing a lot of cutting, cutting thick plate (same air consumption but slower cut speeds = longer cut time) then choose a compressor at 1.5 to 2 times the plasma system requirement.
What I bought:
I went with the best compressor for the lowest price and came across the Home Depot Husky 60 Gal. Stationary Electric Air Compressor. They usually have these hanging around in store and as I am a Veteran of the Navy and get a Military Discount, this was a no-brainer buy for me.

You will also need to pick up a standard Vertical Air Shut-Off valve to put at the output from the tank as well as a regulator and filter. If you are worried about condensation you will want to pick up an air drier as well. The driers are not cheap so do your best to look for the best deal. I am in the desert here in Idaho so I am not too worried about condensation.( I still plan on keeping an eye on it. ) I also bought an under tank drain valve extension for easy access to check for and drain condensation that might be in the tank.
Hoses and quick disconnects will probably be needed and types and quantity will be based on how you plan on setting things up for your table.
Wiring for Compressor
30A double pole breaker for the Husky 60 Gal 220v compressor. I separated the circuits for the compressor and the torch so I could run both without putting them on one massive breaker. SAFETY FIRST!
Make sure you know the type of breaker panel you have and whether or not you have the room to add the required breakers to your system. You may have to hire an electrician if you feel uncomfortable doing this on your own or you need to add a sub panel for your setup.
If you are planning on a long run from your breaker panel to your outlets you will probably want a safety switch as well as adding a heavier gauge cable for the run. Look at the Electrical Code for what your situation will call for.
This compressor is a stationary compressor. You will want to mount this to the floor of your garage or shop. I see quite a few people skipping this step, but its dumb to leave a large compressor like this unbolted or sitting on the original pallet. If it tips you could have a massive electrical issue that could cause harm or death not to mention that you have a large tank with 60 gallons of compressed air that could launch flammable dust in the air causing combustion from the aforementioned possible electrically unsafe situation caused by a tipover. Not something I would want to risk in the garage of my home. Why risk your family? Buy the cement bit, anchor bolts and rent a hammer drill. Its not that expensive when you consider the alternative.
Wiring for the Razorcut 45 plasma cutter
60A double pole breaker for the 45A 220V Plasma Cutter. I have a 50A already for my welder but I am not sure if this is going to be adequate based on whether the plasma cutter pulls a true 45 Amps. If it starts slamming the breaker I may have to upgrade to a 60A breaker as that is a true 25% greater than the suspected load whereas the 50A is somewhere around 12% greater than the possible applied load.
(I might upgrade before I get it the Razorcut 45 just to be safe, but a 50A is more than adequate for the 30A plasma cutting machine Razorweld makes.)
On the cable, check what is required for the length of your run and the amperage requirements. Every situation is different and it is honestly better for you, as the individual installing the equipment, to find the information yourself, diligently, or talk to a licensed professional (i.e. a trusted Electrician).
If you have any further questions, let me know. I will be glad to attempt to answer. Maybe some of them will be answered by Langmuir Systems as well.
