Excerpt from Gas Torch and Thermit Welding

The beginner, the practical worker, the student and the engineer, will find in this book a great amount of information regarding gas-torch and Thermit welding practice and equipment. No toil or expense has been spared to gather material of real and lasting value. Shops have been visited and data and photographs obtained first hand. Practically every book on welding has been carefully scrutinized for helpful suggestions. The services of experts have been engaged to give the results of long practice and research in their special lines. Each and every plan known to the experienced editor has been employed to give the reader the highest possible grade of information.

The historical references have been cut to the barest statement of facts as we have been able to obtain them, yet they are ample enough to give the inquiring mind the genesis of each class. Foreign methods and equipment have not been touched upon, except in a few instances, because such treatment would add too greatly to the bulk of this work, without adding an appreciable amount to its real value, since the methods and standard equipment here are, in general, far in advance of anything similar elsewhere.

Great care has been taken to indicate the sources of information and to give the names and addresses of the makers of equipment shown. It is believed that every well known maker of this class of welding apparatus in the United States has been mentioned at least once in these pages. This has not been done with any idea of advertising them, but because it is information every reader is entitled to have without the necessity of making a separate search for it.

Of course no recommendations regarding the best apparatus to use are made in any case. As in any other line, improvements are being constantly made, but in regard to newly invented or unknown equipment the seller should be made to prove his case before an investment is made.
