(2) For electric-arc welding there are two stationary and four portable sets. All of the sets are driven by gasoline engines and have complete sets of accessories.
(3) The portable sets are mounted on four-wheel dollies and have a welding range of 50 to 400 amperes and a generator rating of 300 amperes at 40 volts. The accessories include a welding-rod assortment, 50-foot electrode and ground cables, gloves, helmets, lenses, and mittens.
(4) For oxyacetylene work, there are three oxyacetylene welding and cutting sets and three portable acetylene generators. The sets include cutting and welding torches and tips, 50-foot lengths of hose, tip cleaners, oxygen and acetylene regulators, spark lighters, gloves, and goggles.
(5) There is also a portable, preheating torch of the atomizing type operated by compressed air.
(6) Miscellaneous equipment in the welding shop includes a brazing and soldering set, ten 225-cubic-foot acetylene cylinders, and fifty 220-cubic-foot oxygen cylinders.
