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.

“I live in a remote Siberian village, which last year was 370 years. Near the river Angara.
