Electric-spark engraving pen EVZ

It’s made in two types and is intended for execution of the inscription by a spark method on the smooth metal surfaces.

This electric-spark engraving pen is the professional tool and favorably differs from its analogues by functionality.

The electric-spark engraving pen is compact and has lightweight. It provides power of a spark sufficient for marking on the majority metals. The 3-step power adjustment of spark will allow you to achieve the best contrast of an inscription at the same time to vary the size of erosion. It’s especially useful for marking of expensive objects.

The electric-spark circuit feeds on low safe voltage. Model EVZ-022 is added with metal working plate for the convenience of the carrying-out inscription on small objects. The plate is electrically connected to a second clip of power unit – for carrying out inscription it’s enough to put object above a working plate.

The device has thermal returnable fuse for protection from overheating. The replaceable wearproof tungsten rod is used as a writing electrode. The service life of the tungsten rod makes up to several years depending on the metals marked. Also, you can always order the new electrodes which are inexpensive account materials.
