Model 700B welder unit -- a portable, lightweight instrument ideal for installing weldable strain gages and temperature sensors to metallic surfaces in difficult industrial and outdoor field environments.
A key enhancement of the 700B is its use of commercially available Lithium-ion batteries that are easily replaced in the field and which can handle 1500 welds (@30 joules) on a single charge (equivalent to welding around 30 linear weldable gage). The lightweight unit, which weighs approximately 8.3 lb. (3.77 Kg), is ideal for field operation, solving the main limitations of other portable spot welders currently on the market. The unit can also be used to weld small thermocouples and light-gauge metal.
