Synergic Multiprocess Inverter CEA CONVEX 405 PULSE

The power sources of the CONVEX PULSE series are characterized by synergistic digital control and inverter technology, integrated in a strong and functional metal construction.
Common Characteristics
Technologically advanced, robust and easy to use, they allow high-quality welding in the following methods:

- Pulse
- Dual pulse
TIG in "Lift" mode

The machines of this series have very easy to adjust welding parameters, which makes them suitable for operators with little experience. After selecting the desired program, the welding control automatically sets the best parameters, based on the type of material, the wire diameter and the gas used (know-how resulting from CEA's 70 years of experience). These power sources are the best choice in all industrial fields, for all applications requiring accuracy and repeatability of welding results. They are especially suitable for light production work and car service activities.


• Digital control of welding parameters with synergistic curves, preset according to the type of material used, gas and wire diameter.
• possibility to save up to 99 own programs
• Intelligent "PROGRAM" button for quick selection of any program
• Professional four-roller wire feed mechanism, with large diameter rollers, for precise and constant wire movement
• Rollers with two channels, for easy change without tools
• "Energy saving" function, to activate the cooling fan only when necessary
• possibility to partially or completely lock the equipment using an access password
• Reduced energy consumption.
• Automatic diagnostics for troubleshooting
• Sturdy main metal construction and protective body feed cover
• Control of seam initiation and crater filling

Built-in features:
'VISION.ARC" function - a special development of "CEA", providing control of the welding arc - short, stable and precise, regardless of the change of external conditions.
VISION.PULSE function – enables pulse welding with a short arc that is constantly adjusted by optimizing the results of traditional pulse welding. This allows reducing the high heat input characteristic of impulse welding, reducing deformations, improving the stability of the weld pool and significantly increasing the welding speed.
DUAL PULSED function - Double pulse, which favors the further reduction of heat input in the processed material, reducing its deformation. The end result is premium quality and an aesthetically pleasing seam appearance. Double pulse is extremely useful especially when welding aluminum and stainless steel.
"WSC - WIRE START CONTROL" function - control at the start of the wire feed. Prevents the wire from sticking to the workpiece or the torch nozzle and always ensures a precise arc with soft ignition.

"BURN BACK CONTROL" function at the end of each welding seam, in any condition and metal, the digital control ensures a perfect "cut-off" of the wire, thus avoiding the formation of the typical weld ball and thus ensuring the best subsequent ignition of the rainbow.
VRD function – to reduce the open circuit voltage below 12V.
