You can find used plasma cutters online and in the real world. If you find a used plasma cutter you have to make sure that it is in good condition and, more importantly, you have to find out if the unit meets your needs. Use the following list of questions to assess any used plasma cutter that you find. When you have the answers, you will be in a much better position to make an educated buying decision.
- Is the cable insulation worn down from use?
- Does the sever cut, rated cut, and quality cut of the match what I need?
- Are the cuts still clean?
- Has the machine ever been repaired or serviced?
- Is there still a factory warranty?
- Is there a power source at my business or home that matches the power requirements of the machine?
- What is the duty cycle of the unit?
- Are the diagnostic lights and controls functioning properly?
- If I buy the machine do I get any consumables?
- What is the condition of the internal components (if they are in good condition then the owner probably took good care of the machine)?
It is most important that all of the cables are in good condition. Electrocution is no joke and no matter how safely you operate the machine, if there are exposed cables you are in danger. It is better to spend a few dollars more than to put yourself in a dangerous situation.
You may find it to be a pain to try to answer all of these questions, but it will be worth it. I would rather put in the time to find the right machine on the first try as opposed to kicking myself for buying a piece of junk.
