The UN-T rod butt welder is particularly suitable for the butt welding of metal wires and metal bars made from low carbon steel and stainless steel with diameters less than 20mm. The welding machine creates welds with reduced residual stress and removes burrs formed through a resistant welding process.

Features Pneumatic clamping device prevents material slippage between electrodes and ensures stable welding quality. A track carriage guide with two axes boasts high accuracy and wear-resistance and provides running stability to create consistent joints. Easy-to-use microprocessor precision control enables quick switching between different welding parameters. Parameter
