Page 7: Using The H20 Welder
USING THE H20 WELDER Start Up: 1. Plug the electric cord to the appropriate 110V 220V electrical outlet. 2. Locate the chrome cap on top of the cabinet. This is the water tank inlet spout. Turn the toggle switch to the REFILL position. The greenish yellow minimum light will go on. - Page 8 NOTE: Boric acid powder can be added to the methyl alcohol solution in a ratio of .5 to .7 ounces per quart. This should be premixed. Boric acid with methyl alcohol provides a reducing characteristic to the flame. This will keep your parts cleaner when brazing (hard soldering).
