Welding machine ZPM-80/ for pipes

TECHNICAL DATA

• Welding capacity – 5 mm + 5 mm sheets
• rated power 50% – 80 kVA
• welding current ( for 6% cycle) 18 kA
• clamping force 700 daN (at 6 bar)
• usable depth 285/285/485/585 mm
• microprocessor controller ASM-913

TECHNICAL DETAILS

• Single or serial operation
• Infinitely adjustable bottom overhang height
• Pneumatic components requiring no lubrication and eliminating oil mist ejection
• Water-cooled transformer and secondary circuit , i.e. electrodes, electrode holders and welding arms
• Throttle-return valves to control the speed of the electrodes, and compressed air bleed dampers to reduce noise levels.
• A foot-operated two-stage start button that, in addition to the function of single or serial operation, allows two workpieces to be pressed together without current and, after checking the positioning by pressing the button deeper, welded in a fixed position
• Synchronous, water-cooled thyristor with built-in protective thermostat and phase-cut current control
• Electrode force regulated by a pressure regulator unit equipped with a pressure gauge and a filter for automatic air stripping
• Optional proportional valve to electronically control the clamping force of the clamping system
• Safety switch immediately shuts down the welding machine
• Possibility to use bent, flat and special electrodes
• CE mark
