The seam welder model FN1-150-5 is specially designed for
welding thin-walled barrels made of low carbon steel sheets without
coating and is also fit for welding steel plates of low carbon and low
alloy steel. It is equipped with a syncronous thyristors control cabinet model KF4-500-1.
The welding force can be steplessly adjusted and remains constant in
despite of fluctuation in compressed air pressure and wear of the
welding wheels.The amount of wear may be compensated by adjusting the
distance between two wheels to regain the original value. http://www.autoweldingmachine.com/
