Features:
High frequency inverter technology, small size, light weight, and high energy density. The core control component of the main machine is a PLC microcontroller; the welding current and welding time outputs are more accurate.
Core components are selected from international top brands; the Anti-repeat welding function can eliminate the secondary welding caused by the equipment or accessories damage.
One machine for multiple uses: simple conversion between stud welding and manual arc welding, easy to use.
Fields of application: construction site stud welding in the steel construction industryWelding of water-cooled or Y-shaped nails in industrial furnaces.Wear-resistant stud welding in the mechanical engineering industry.
