what equipment do you use to break down rusty over old equipment?

lots of times rusty old screws are best approached with a hammer and cold chisel, or drill the head off it, depending on what you're looking at, and what you've got in your hands, and if you're just all out scrapping, or hoping to save a piece of it

yea the good old oxy/acy torch setup with various size cutting tips 00-3 depending on what im cutting also a rosebud tip for heating if your trying to reuse somthing a brazing tip also comes in handy for welding/repairing thin metals, 6" metabo, various size pry bars and hammers plus other assorted hand tools have a chop saw also it does wonders with smaller scrap items

if your budget is limited id just go with an angle grinder, hatchet a couple good hammers and a few screw drivers

i part out 4-8 cars a year and have a fully equipped shop with compressor, various welders, torch setup, overhead monorail beam with trolley and chainfall, and tons of hand and power tools

dewalt impact gun when that fails i use oxy/acy torch

forgot to add air chisel, they do wonders scrapping. And also sometimes use a spot weld cutter if i am trying to pull welded on body part for a buyer.
