The tool is shown as being secured to an annular flange 34 on the transformer housing, a hollow extension II being connected to said flange. The hand grip portion or the handle may be secured in like manner to the upper end of the transformer housing.
This type of tool is ready for instant use when connected to alternating essary for the artisan to carry a separate transformer. It may be plugged into any convenient outlet for immediate use.
In Fig. 4, the tool shown in Fig. 2 is slightly modified for welding and brazing. In this instance, the tip II' and the short extension 20' are removed and replaced by a screw bushing 4| and a long extension 4|, respectively. The bushing is made of insulating material and serves to hold the porcelain sleeve II in place. The extension 4| has a split socket 42 to receive a carbon electrode 0. A clip 44 is secured to the tube H and a conductor ll connects it to the ized parts. They are easy to operate and will comply with all requirements of the underwritcircuits. It is not necera. The carbon'electrodes are easyto replace by The welding rod exwith the short conmay be used for braling. The tool is always ready take the place oi practiirons and similar weldremoving the soldering tip. tension is interchangeable for instant use. and will cally all other soldering ing tools.
Obviously, the present invention is not restricted to the particular embodiment thereof herein shown and described. Moreover, it is not indispensable that all of the features of the invention be used coniointly, since they may be employed advantageously in various combinations and sub-combinations.
What is claimed is:
An electric soldering tool oi the character described comprising, in combination, a handle; a step-down transformer associated with the handle; a switch in the transformer circuit; a metal tube connected to one terminal on thelow voltage side of the transformena soldering tip on the metal tube; a carbon electrode in the soldering tip; a conductor mounted in and insulated from the tube; and a combined compression spring and conductor connecting the upper end of the rod to the low voltageside of the transformer to maintain said rod in contact with said electrode.
