Detailed Specifications:

The Studhorse 1200DM uses a power supply that is based on inverter technology. The machine weighs only 90 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. Furthermore, 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 also 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).

Easy to Use!

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.

The weight of the Studhorse will drastically increase operator efficiency. Additionally, the 50% weight reduction in the machine and the 70% lighter power cord make stud welding significantly more economical! Because of its weight, the Studhorse allows easy loading by hand on and off any vehicle!
