MultiCam Plasma machines are available at 1000 Series, 3000 Series, 6000 Series, and the V-Series Plasma. Each model comes with your choice of a zoned downdraft or a water-filled CNC Plasma table. Some of the pros and cons between the two are listed below:
| Downdraft | Water Table | |
|---|---|---|
| Pros | Applicable for a variety of metalsDowndraft collects particles and fumes transferring them through a filter system to clean the airEasier to cleanMore versatile, if you desire expanding your production by extending the table, it is easier to do so with a downdraft | Limited to only plasma and oxy-fuel thermal cuttingBest applicable for cutting mild steelParticles or fumes are pushed into the water so none remain in atmosphereLess expensive to install and operate because there’s no need for a filter or a fume collectorLess noise, no sparks and reduced arc glare |
| Cons | Filter must be changed regularlyWhen metal being cut changes, a different filter appropriate for the application needs to replace the one priorMore time consuming when removing or adjusting certain parts on the table, having to wait for them to be cool enough to handle with gloves or tongs | Water must be added on a regular basis along with chemicals to prevent algae growthMust also be drained periodically and legally disposed ofNot recommended for some plasma cutting surfacesMaintenance costs are typically higherWhen cutting aluminum, hydrogen bubbles can build up under the aluminum plate from the molten aluminum dropping into the water, creating the possibility of an explosion |
There are many pros and cons that exist and no right answer to which is better. It’s a give or take situation where one aspect that proves to be a disadvantage is traded, in order to obtain a positive point. It all Depends on the type of business you run and the needs you require.
