Modified Tombstone Welder Contains a Host of Hacks

State-of-the-art welding machines aren’t affordable, and for just right reason why: pushing round that a lot present in a managed means and doing it over a complete workday takes some heavy-duty portions. There are bargains to be discovered, even though, particularly in essentially the most elementary of machines: AC stick welders. The acquainted and aptly named “tombstone” welders can do the industry, they usually’re a useful tool to learn to lay a bead.

Tombstones aren’t with out their drawbacks, even though, and whilst others would possibly purchase a special welder when bumping up towards the ones limits, [Greg Hildstrom] made up our minds to Mod his AC stick welder into an AC/DC welder with TIG. He main points the panoply of mods he made to the welder, from a brand new 50 A cordset produced from three extension cords the place all three 12 gauge wires in every wire are attached in combination to make a lot greater efficient conductors, to including rectifiers and a choke produced from the body of a microwave oven transformer to supply DC output on the complete 225 A score. By the tip of the venture the tombstone was once chock stuffed with hacks, together with a do-it-yourself foot pedal for voltage regulate, new industry-standard connectors for the whole thing, and with the assistance of a antique Lincoln “Hi-Freq” controller, give a boost to for TIG, or tungsten inert gasoline welding. His weblog put up presentations probably the most many check beads he’s put down with the system, and the video playlist related under presentations highlights of the construct.

This isn’t [Greg]’s first foray into the arena of scorching steel. A couple of years again we coated his electrical arc furnace construct, powered via some other, extra succesful welder.
