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
