The Speedtec® 400SP and 500SP are third generation multi-process power sources offering superior quality welding with high efficiency processes which increase the productivity and are the next step in the future of professional welding.
The range is designed with the latest energy-saving inverter technology and rugged construction making them ready to work in even the most demanding environmental conditions. Available in two versions – the 400SP and 500SP are paired with the advanced LF56D for more demanding applications. The new Coolarc® 60 cooler adds higher cooling efficiency, while the new four wheel cart with solid metal construction offers great functionality. A wide range of connection cables and accessories fit perfectly with all needs from most demanding welding applications in various segments. The Speedtec platform is based on a digital communication system with build-in communications tools, such as ethernet or USB, allowing for accurate traceability and monitoring of your welding activities for outstanding welding performance.
Speed Short Arc™ (SSA™)
A semi-controlled short circuit mode which allows to shift globular behaviour using wire feed speed normally reachable only in pulse mode. The current values used in this mode are very different from those used in conventional “short arc” operation. Faster wire speeds require a medium current together with a large peak current in order to form and detach the droplet more quickly.
Soft Silent Pulse™ (SSP™)
This is a pulse transfer with a special waveform producing a soft and silent arc. The behaviour of the Soft Silent Pulse™ is very suitable for stainless steel application which requests the best wetting possible. Silence, because the noise of the arc is divided by two regarding a normal pulse mode what can be really appreciated when you have to weld in a confident area. Moreover the stability given by this transfer allows to weld in all positions and especially in vertical up without weaving when it is associated to a MechaPulse™ welding mode.
High Penetration Speed™ (HPS™)
HPS™ (High Penetration Speed™) is a special spray mode but with a focused arc offering higher penetration and combining two different main advantages: provides lower voltage and so lower energy; very accurate and dynamic regulation of the welding parameters. This association is able to carry out very high productivity with the optimal welding performance.
