Direct (Rectified) Current Resistance Spot Welding Machine MTB-80.02-1
OKP 34 4142TU 16-739.024-75
This machine is designed for direct (rectified) current resistant spot welding of various (including large-dimensioned) heavy-duty items, e.g. shell rings, frameworks and other load-bearing elements. The maximum dimensions of the welded items depend on the electrode stick-out distance, welding circuit aperture and upper electrode travel.The design of the machine enables it to be used in any industry for welding of aluminium and titanium alloys, stainless, heat-resistant and carbon steels, as well as some grades of brass and bronze.
The machine is equipped with programmable microprocessor controller
