Automatic gas welding machine for heat exchanger production

Application scope

This automatic welding machine is used in heat exchanger production where workpieces move through a controlled gas welding station. It is suited for factories that need stable handling for coil-related assemblies and want the welding step matched with their workpiece height, row count and fuel gas supply.

Catalog configuration range
