CEA power sources are standard equipped with analogic-digital I/O. This allows to integrate very easily the power source into an automated welding equipment without any expensive and sophisticated external interfaces, usually necessarily supplied for robotics.

Innovative spot welding device to achieve precise and safe joining with a minimal thermal input.

Multi-cold.TACK function grants cold spotting in a rapid sequence, thus further widening the benefits of the single spot.

Thanks to Perfect-Point function, cold.TACK allows to obtain the most precise spot positioning.

RCT is the acronyms of Running cold.TACK; indeed, the TIG RCT process allows to benefit of all the cold.TACK advantages, by repeating the single cold.TACK point in a continuous way, in order to achieve a cold and perfect welding seam.

Using TIG RCT the welding seam is much colder in comparison to the one achievable with Pulse TIG and it represents the ideal solution to weld thin materials with a very low heat transfer. TIG RCT is a direct current process not available in AC welding.

“CYCLE” function allows to continuously switch between two current values, by previously preselected simply pressing the torch trigger. This function is most suitable for welding different thickness profiles, requiring a continuous current adjustment change.

SYN PULSE

SYN PULSE will synergically generate pulse frequency and base current

ULTRA FAST

Adjust frequency up to 2000 Hz

FAST PULSE

Adjust frequency from 0,5 Hz to 500 Hz

SLOW PULSE

Adjust separately current/time of peak and base

Possibility of independently adjust both current time (t) and its amplitude (A) while staying in either positive or negative polarity, by offering a perfect control of penetration and arc cleaning with a drastic reduction in lateral undercuts.

DYNAMIC

Square wave: high arc dynamics for all applications

SOFT

Sinusoidal wave: smoother and softer arc with a reduced noise, ideal for medium thickness

SPEED

Mixed wave: optimal penetration at high welding speed and low consumption of the electrode

COLD

Triangular wave: low heat transfer with reduced deformation, ideal for small thickness

Frequency adjustment of the various AC wave shapes for better directional control, reduction of the thermally altered area, deeper penetration and electrode lower wearing out.
High level frequency enables to weld very thin material with excellent results. Low frequency is ideal for medium thickness or whenever edge preparation is not accurate.

Compared to the traditional positive ignition, it is possible to take advantage of the special negative ignition mode. With this function, possible inclusions can be further reduced during the ignition phase.
