ROCKER ARM SPOT WELDERS

ADJUSTABLE HEIGHT LOWER ARM

K-KP 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. K-KP models are supplied either mechanical or air operated:

K is mechanically operated pedal
KP is pneumatically operated by electrical pedal.

K – KP 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
Welding current and time electronic adjustments
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 (KP)
High versatility thanks to all different possible work configurations
Lower arm with adjustable height which can be rotated for use with a longer electrodeholder (Optional K/KP)

Technical features
