  • Plasma Cutter Info needed

    I work for the local fire department and we are looking into adding a plasma cutter to our heavy rescue rig. I'm looking at the 375 and the 625 but I'm not sure which one would work the best with our power supply. We have a 6000 watt generator that has 220. My question is that If I dial the 625 plasma cutter down can I use it with the generator and then If we get to incident and have a better power source we could use it to it max capacity then.

    Do you have high volume 70 psi clean air?

      I'm guessing those yellow things they carry on their back with 2200/4500PSI in them might be able to supply 70PSI fairly good...... be good and dry air too.

      Besides I think that they are using them for small cuts, like security bars not really needing to make long cuts.

      I might be wrong?????????

        Yes like railmen said we have a good supply of air with our SCBA bottles (Each bottle has 87 cu.ft.) and air compressor on the rig. The air compressor is 5.2cfm and is .8 shy of the needed capacity for the 625. As far as use of the unit, it is hard to say. We respond to all types of incidents and could be cutting anything from rebar in tight spaces to components of a collapsed structure.

            Probably not the best of ideas, being FIRE fighters and all. In order to cut something, you'll be spraying molten metal around.

            Really better off thinking liquid nitrogen to break steel or hydraulic breaker jaws.

              It's just another tool in the toolbox. Obviously we wouldn't be using it if molten slag was going to be an issue.

                  Do you know anybody with this product? It seems like it could be difficult to work with in smaller spaces. Looks like it works great if that's not an issue though.

                    Runown,
                    Out of curiosity, what type of Rescue are you trying to equip? What level of training and responce are your members equiped to handle?

                    The generator, does this also power the lights, fans, vent systems, and saws also needed on the scene?

                    I think it may be harder to power such a tool than you think. I also wouldnt count on an on-scene power supply being readily available unless its another one of your rigs.

                    Just some food for thaught, Robbie

                      I've used the slice system and it works well. You have to hook it up to an oxygen cylinder ( not compressed air ). It will not only cut metal, but concrete, etc. Not the best thing for tight spaces as it blows slag ALL OVER the place! A lot of this finds it's way onto the operator as well. The consumable rods it uses are pretty pricey and don't last long, esp. in heavy cutting.
                      Sometimes there's no second chances.

                        Yes

                        The answer to your question is yes, the 625 will operate at reduced input power. With 6000 watts you might be able to cut 1/2" at 6"/min, as that's what the 375 does at 4000 watts or 27 amps out put.
                        At full out put (8000 watts) the 675 will sever 7/8" at 4"/MIN.
                        I just when through something similar with my Trailblazer 302 (9500 watts).
                        I will be able to run my 120amp plasma at 40 amps output, but that's it.
                        Good Luck

                          WOW! that looks like a great product. Imagine you are being rescued and the Fire Dept is jacking around with a plasma cutter running their air lines and rigging power and all that and then slowly sawing thru thick steel to get to you, when with this sucker all you gotta do is light it and go and blow right thru 3" thick steel. You would not need to be very accurate which is something that a with plasma must have....accuracy.
                          I think every junk/scrapyard could use one of these.
                          The fact that it can work while being sprayed with water is nice. I wonder if they are simply saying if you was using a plasma cutter in the same situation you just might get your @$$ shocked into the future?
                          I am sure those rods are not cheap but neither is the time wasted saving a life.
                          Just the fact that this product is coming from a source that mfgs cutting torches and plasma cutters says a great deal to me.
                          At the very least I would have companies come and DEMO these machines to make an informed decision.
                          I believe Fire and Rescue needs every tool known to man when the time comes so good luck in deciding, and please keep us updated on you decision

                          P.S. Dave...how do you continually FIND all this stuff???? You and Brocoli could start a biz just making suggestions to companies on what the heck to do!!!
