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.
