Using a plug-in concrete vibrator is a good idea for a variety of reasons. Aside from being a fun way to get the job done, it can help you save money on cement.
A plug-in concrete vibrator is a four-part machine that consists of a flex shaft, a handle, a rhomboid shaped motor, and a 45 cm long flexible tube. The tube has a diameter of 16 inches, which isn't too shabby. The motor is a 1000 watt or 2000 watt model that runs at 4000 or 4500 RPMs. The flex shaft is the heart of the machine, as it rotates an eccentric weight inside a vibrating head. The rhomboid shaped metal shaft makes for a nifty and slick looking machine.
The all-purpose paint mixer is a great machine to have in your arsenal, especially if you're working on a small batch of concrete. It's also ideal for mixing thinset, painting, and drywall patching.
The best part of the plug-in concrete vibrator is that it can be moved around, making it easy to operate on a range of sites. It's also a lot lighter than other machines, meaning it can be transported easily. The E-class insulation characteristics of the rhomboid shaped unit are another plus.
The plug-in concrete vibrator may not be the most effective concrete forming device, but it's the most versatile and it certainly is the most useful. Aside from helping to mix up a batch of concrete, it can also be used to compact soil and dust.
