FN Seam Welding Machine

Switch between continuous seam welding and pulse welding directly from the control panel. Continuous mode maximizes throughput on standard galvanized steel, while pulse mode reduces heat distortion on thinner stainless steel sheets — no tooling changes required.

Air-driven electrode force up to 1,000 KGF keeps roller electrodes firmly seated against the workpiece throughout the weld path. This eliminates inconsistent contact pressure that causes burn-through or cold joints, especially on curved and cylindrical parts.

The 600 mm arm length across all four models allows operators to weld inside ducts, tanks, and sealed containers without interference. The 80 mm stroke provides clearance for loading and unloading parts quickly between cycles.

From 45 KVA on the FN-35 to 110 KVA on the FN-100, each model targets a specific thickness range. This means buyers invest only in the capacity they need — a workshop welding 0.4–1.0 mm duct seams does not pay for a 2.0 mm-capable power supply.

Water-cooled electrodes maintain stable operating temperatures during high-duty-cycle production, reducing electrode wear and unplanned downtime. The uniform machine dimensions across the range simplify factory layout planning whether upgrading from a smaller model or running multiple units in parallel.
