ROCKER ARM SPOT WELDERS

ADJUSTABLE ARMS LENGTH

Z and ZP series resistance spot welders, versatile, robust and easy-to-use, ensure best welding results on any weldable metal and are the most ideal solution for all spot welding applications.

Z models are supplied mechanically operated pedal, whilst ZP are pneumatically operated by electric pedal

Z – ZP lower arm fitted with pressed-in electrode (optional)

Whenever the lower arm is fitted with a pressed-in
electrode, also a long electrodeholder is necessary on the upper arm.

Other characteristics

Excellent welding on all weldable metals
Electronic adjustment of the welding current and time
Synchronous ignition SCR group with phase shift welding current adjustment to eliminate initial transient
Reduced consumption
Water cooled arms
Water cooled copper electrodeholders with adjustable height
Self-lubricated pneumatic components to eliminate oil deposits and to safeguard the environment from contaminants (ZP)
High versatility thanks to all different possible work configurations

Technical features

FLEXIBLE PRODUCTION Z-ZP

This is the most suitable solution whenever is required an extreme flexibility.
