ZD7-2000 Submerged Arc Welder

ZD7-2000 inverter multi-process arc welding power source. Design features - Compact footprint that saves valuable floor space - Penetration control advantage: deeper penetration without increasing heat input - Controllable penetration with repeatable parameter accuracy - Fast arc starting - One machine for submerged-arc welding, manual arc welding, carbon-arc gouging and electroslag welding - Good bead appearance and a wide range of matched applications - IP23S protection rating for improved safety - Heavy industrial rating: 100% duty cycle at 40 °C for severe operating conditions Applications Mainly for carbon steel and its alloys and stainless steel. Widely used in steel-structure buildings, bridges, locomotives and ships, pressure vessels, spiral-welded pipe and large forgings. Why 2000 A 2000 A is the top of the ZD7 range, built for the largest sections a fabrication shop handles: heavy pressure vessels, large forged and welded structures, and thick-wall components for hydropower and thermal power. It is normally installed as part of a fixed automatic welding station with flux handling and seam tracking.
