ROCKER ARM SPOT WELDERS, FOOT AND AIR OPERATED

MEDIUM FREQUENCY, ROCKER ARM SPOT WELDERS, FOOT AND AIR OPERATED 25kVA

Medium frequency, pedal and pneumatic oscillating arm spot welders 6010..6013, nominal power at 50% continuous current 25kVA.

Welder with inverter technology designed to obtain high quality welds with a reduction in costs.

Adjustable arms in length that allow greater work flexibility.

Copper-chrome electrode holder suitable for heavy duty and long service life, designed for straight and inclined mounting.

Stroke of adjustable welding electrodes. Encapsulated transformer in water-cooled epoxy resin; arms, welding electrodes and electrode holders are water cooled.

Easy and intuitive welding control with time and manual potentiometer adjustment.

In resistance welders with pedal operation, the force of the electrodes is adjustable; a microswitch controls the welding cycle when the set value is reached; the pedal is adjustable in length.

In the pneumatic powered resistance welders, the pneumatic controls and the compressed air pressure gauge were positioned at the top to facilitate adjustment and reading operations.

The pneumatic cylinder works without lubrication without emitting oil mist.

The force at the welding electrodes is adjustable with the filter-reducer unit and with the pressure gauge.

Semi-automatic condensate drain, cylinder end-of-stroke damper and exhaust silencers.

The pedal allows normal use in a single cycle to tighten the correctly positioned parts.

The main advantages of a medium frequency system compared to a traditional AC system are: excellent precision on current control thanks to double feedback, in fact every 500 microseconds the system checks the output current both before and after the welding transformer.

Reduction of operating and maintenance costs, to obtain the same welding, a traditional AC system would require a higher installed power and a higher withdrawn line current.

Furthermore, thanks to the reduced welding times, maintenance on welding electrodes is reduced and greater productivity is achieved.

Compared to the AC welder, the medium frequency system also produces a much more efficient heat supply and this allows to obtain the same welding with less time, reducing the heat dispersed around the welding core avoiding to alter the characteristics of the material.

Compared to welding machines in AC a balanced network load and an absolute independence from the grid frequency.

It always keeps the welding current constant even in the presence of variations in the line voltage, of the secondary circuit impedance, of the conditions of the welding tools and of the surface conditions of the material to be welded.
