Sure: from a compact and yet sufficiently reliable, cheap and simple to manufacture “svarochnik” no workman, Thrifty, the owner will not refuse. Especially if he knew that at the heart of this machine is easily upgradable 9-ampere (familiar to almost everyone from school physics lessons) laboratory autotransformer ЛАТР2 Yes homemade mineralwater with thyristor rectifier bridge. They allow not only to safely connect to domestic lighting AC voltage of 220 V. but to change u on the electrode, and means to select the desired value of welding current.
The proposed electrosurgery, I am sure, will find its rightful place in the kitchens have gas stoves, when the ignition of the gas burner appliances and other devices with the “blue fuel”. It is convenient and trouble free. It can make for a night or two, pre-armed with a small piece of one-sided foil fiberglass and a minimum of inexpensive and common parts. A faithful guide to action will serve as a sketch of the printed circuit Board and Assembly drawing.
I made welding machine is a well-proven in practice a modernized version of the device description and drawings of which are published in the journal “modelist-Konstruktor” No. 3, 1966. Most importantly — new “svarochnik” significantly more powerful than its predecessor, easier to manufacture and operate. In the absence of the kind of “bells and whistles” it allows you to securely connect steel sheet with thickness up to 3 mm. However, the mode of operation is one of the most necessary most homebrew spot welding.
Familiar to many hams, the situation: once the scheme is built, configured, but… to Squeeze it into some kind of “soap” not want to, but new to “diamond” the right frame there is neither time, nor forces. Had to find a way out of similar situations and me while in one of the publications, “Model construction” did not find a clue. It turns out that enterprising and slopestyle Siberians, which wrote the log, began the production of fine gift boxes of foil materials commonly used in the manufacture of printed circuit boards. Moreover, the simplest technology: the workpiece-scan in the field of future folds (from the base-insulator), they made cuts, and after giving it a box shape was probabaly foil joints.
I designed the machine addressed to the farmers and owners of summer houses with auxiliary water supply system, key units of which are a water source (river, lake, well or borehole), water tank electric pump Yes. From analogues this development is characterized in that in addition to performing its main function — control the electric pump makes it quite successfully solve tasks of protection of objects. This unusual flexibility is achieved not by complexity of an electrical circuit device, and by quick-change sensors, which are not only submersible multi-level electrodes and photoresists or thin, working on the rupture of the wire.
