America’s first full size, lightweight, portable drawn arc stud welder, The Studhorse-1200DM, uses a power supply that is based on inverter technology.
The machine weighs only 80 lbs. (36.5 Kg), with physical dimensions of only 19.5" long x 17.9" high x 10.5" wide (495 mm x 455 mm x 105 mm). Generating an output of 1200 Amps, the welder is capable of welding studs up to 5/8 in. weld base diameter.
The unit can be powered from a 40 Amp utility breaker at 480V, 3-phase or from a 30 Amp time delay fuse. The welder features infinitely adjustable output current, up to its 1200 amp. max., allowing for a wide range of stud sizes.
Note: the 240V model requires a 60 amp breaker or slow-blow fuse and a 200 amp supply circuit for maximum output.
Many competing 1200A arc stud welders on the market today are still using the conventional linear power design technology, with a typical weight of almost 200 lbs. (90 kg).
The Studhorse 1200 can easily be moved with the operator as the welding job progresses and connects with a 4-conductor, 10-gauge power cord to either a utility grid or a power generator. With The Studhorse 1200 kept close to the welder, only a short welding cable is needed. This considerable weight difference will drastically increase operator efficiency, and more applications of stud welding will also become economical due to the 50% weight reduction in the machine and the 70% lighter power cord. For the contractor on-the-move, the light weight Studhorse allows easy loading by hand on and off the back of a pickup truck.
