Product Overview

-
The ZF-1500 stainless steel seam welder is an automatic longitudinal straight seam welding machine designed specially for stainless steel sheet fabrication.
-
This stainless steel seam welder adopts pneumatic piano clamping structure, which fixes metal plates tightly during welding.
-
It effectively reduces thermal deformation for thin stainless steel material and produces smooth, dense and leak-proof longitudinal weld seams.
