Abstract
646,250. Electric welding. MILLER ELECTRIC MANUFACTURING CO., Inc. July 8, 1948, No. 18389. Convention date, March 16. [Class 83 (iv)] A portable, manually operable spot-welder comprises a pair of welding-tongs mounted on one cap of a transformer core and connected to the single turn transformer secondary, and a handle secured to both caps and spaced from and extending along the core. The laminated core 1 held together by corner bolts is formed of recessed halves to contain the primary winding 5, e.g. of seventy-two turns for 110 v. supply and a single turn secondary 7. A fixed tong 8 is insulated from one end cap 4 and is held by a clamping plate, see Fig. 5 (not shown). The movable tong 9 is connected to the secondary 7 by a flexible strap conductor 16 and is pivoted on a pin 15 of a block 14 swingable in a recess in the cap 4. An open channel handle 20 secured to the cap 4 and the other cap 3 contains the supply leads to an operating switch 25, and a co-operating channel lever 18 protects the leads and is pivoted to the handle 20 to operate the block 14 through a toe 26 to close the tongs 8, 9.
