Referring to Mr. Candy´s comments on a-c. welding equipment in his article published in the Journal for June, 1920, it must be that he has drawn his conclusions from apparatus which he has constructed for his company. At least we know that no part of his comments refer to our a-c. welding machine although the article definitely classes all a-c. welding as poor. For instance, he makes the statement, “To make the equipment commercially successful in the hands of the average welder it is necessary to use an especially prepared electrode.”
