Greetings on the channel for beginners garage-country self-taught in welding and locksmith!
The welding inverter and grinder are the basic tools of the home craftsman working with metal. Who decided to take the path of working with metal, this is a useful article-hint on how to properly start your first cuts with a grinder.
All novice carvers have one and the same problem, if no one has explained them in detail in advance. We begin to cut, but it becomes more and more difficult to cut, it is already difficult to hold the tool, the cut itself is very slow. Here's what happens.
The beginner puts the disc on the markings and waits for it to cut through the metal. The disc, as it deepens, begins to meet more and more resistance to its rotation. The contact area between the disc and the metal just increases, so everything goes hard and slowly. How else, how correctly and easily?
When we start cutting, we need to immediately bury the disc into the metal from the edge of the cut in order to complete the entire cut with minimal resistance. With this cut, the contact zone of the disc with the metal will be minimal, the cutting speed will increase several times, plus it will be very easy to hold the tool. How long should the disc be buried in the metal?
If the disk is conventionally taken as a clock face and roughly divided its circumference into sectors, like time, then it will turn out like this. From many years of practice, it has been noticed that it is easiest to cut with a grinder's disc in a sector between 7 and 8 o'clock.
So, as in the photo, right from the edge we deepen the disc to the conditional 7-8 o'clock and drive the disc a little in this range between 7 and 8 o'clock, we easily and simply cut the required metal.
But a beginner is sometimes afraid to bury the disc into the metal, and may be right at first, until the hand gets used to holding the tool in exactly one position, in order to avoid disc distortions. Then the first time you can cut like this.
You can quickly drive the disc forward and backward along the markings. In this case, the area of contact between the disc and the metal will also be minimal. It's just that the disc does not have time to go deeply, so we gradually remove the metal at the cut point until the workpieces are completely divided into 2 parts.
So take these methods into your arsenal of technical knowledge and apply them, the result will please you.
