CEA ZP 28 Pneumatic Rocker Arm Spot Welder 25 kVA

CEA ZP 28 Pneumatic Rocker Arm Spot Welder 25 kVA

The CEA ZP 28 25 kVA Pneumatic Rocker Arm Spot Welder is a heavy-duty resistance spot welding machine designed for high-volume sheet metal fabrication, industrial workshops, and repetitive production applications. Operating on a 400V single-phase supply, it delivers up to 11 kA welding current and 300 daN pneumatic electrode force for strong, consistent welds. Featuring electric foot pedal operation, programmable welding control, and adjustable water-cooled arms, the ZP 28 provides precision, efficiency, and dependable performance for demanding welding environments.

Key Features & Benefits

Pneumatic Operation with Electric Foot Pedal
Features an electric foot pedal that activates the pneumatic cylinder, delivering up to 300 daN electrode force at 6 bar. This ensures consistent clamping pressure while reducing operator fatigue during repetitive welding.

Powerful 25 kVA Welding Performance
Equipped with a 25 kVA transformer delivering up to 11 kA maximum welding current, providing strong, repeatable spot welds on mild steel, stainless steel, galvanised steel, and other weldable sheet metals.

CEA WS 750 Microprocessor Welding Control
Features the CEA WS 750 STD microprocessor controller with 100 programmable welding JOBs and USB connectivity, allowing operators to store and recall settings for consistent weld quality across production runs.

Adjustable 250–600 mm Rocker Arms
Features adjustable-length welding arms ranging from 250 to 600 mm, allowing operators to reach deep panels, complex sheet metal assemblies, and difficult welding positions with greater flexibility.

Self-Lubricating Pneumatic Components
Designed with self-lubricating pneumatic components that eliminate oil deposits on workpieces, helping maintain clean welds, protect surface finishes, and reduce maintenance requirements.

Water-Cooled Arms & Electrode Holders
Equipped with water-cooled Ø 40 mm welding arms and electrode holders with Ø 16 mm electrodes, helping manage operating temperatures and maintain consistent welding performance during extended production runs.

400V Single-Phase Power Supply
Operates on a 400V single-phase, 50/60 Hz electrical supply with a 40A delayed fuse requirement, delivering dependable power for industrial spot welding applications and repetitive fabrication tasks.

Complete Pneumatic Spot Welding Package
Supplied with the CEA ZP 28 400V spot welder featuring WS 750 STD control, adjustable 250–600 mm water-cooled arms (Ø 40 mm), electrode holders with electrodes, and an electric foot pedal for convenient operation.

Installation Note: The ZP 28 requires a separate compressed air supply of 6 bar (600 kPa) and a suitable cooling water supply. The IR 14 400V water cooling unit with connection kit is available as an optional accessory.
