      Pulse Characteristics

      steel, stainless steel, and aluminum. This means that no matter the welding task at hand, the TransSteel 4000 is equipped to deliver exceptional results. The Pulse system on the TransSteel 4000 offers unprecedented control and precision. With 57 adjustable pulse characteristics, operators have the flexibility to fine-tune their welding parameters to achieve optimal performance. Whether you need to weld thick steel plates or thin aluminum sheets, the TransSteel 4000 can adapt to the specific requirements of each material. Not only does the TransSteel 4000 offer a wide range of pulse characteristics, but it also ensures ease of use. The Fronius team has carefully developed specialized pulse characteristics for the most common materials - steel, stainless steel, and aluminum along with many more. This means that operators can simply select the appropriate preset and start welding without the hassle of manual adjustments. The TransSteel 4000 takes the guesswork out of welding and streamlines the entire process, allowing operators to focus on what matters most - getting the job done efficiently and effectively. With the TransSteel 4000, you can trust that you have the right tool for any welding task. Its advanced Pulse system and tailored pulse characteristics make it a versatile and efficient solution for various materials and applications. No matter the complexity of your welding project, the TransSteel 4000 is here to deliver outstanding results every time. The perfectly crafted pulse characteristics were crated for the following materials:

      • Steel - Mild steel, cold rolled, Stainless steel
      • CrNi - Chromium/Nickel
      • FCW - (Metal Cored) 
      • CuSi - Copper Silicon
      • AlMg5 - Aluminum/Magnesium
      • AlSi 5 - Aluminum Silicon 
      • Including - PCS characteristics for steel 0.8mm/1.0mm/1.2mm/1.6mm

      Pulse Controlled Spray Arc 

      The pulse controlled spray arc is a very precise and unique feature. A conventional electric arc burns above the weld pool and sprays the filler material into the pool, where the PCSA (pulse controlled spray arc) will spray the filler wire not only into the weld pool but will push the arc past the weld pool and deeper into the work piece material. Focused arc with the PCS allows low process voltage to enable narrow arc focus where arc pressure is specifically applied into the component. Resulting in deep, narrow penetration for a much cleaner, stronger yet smaller weld. High arc pressure will not light up the arc, but presses on the weld pool. 

      Advantages for the operator:

        • Reduced light and heat radiation - Arc pushes on the weld pool
        • Despite relatively low welding parameters, reliable detection of the root edge
        • Lower energy input due to reduced voltage

      The pulse controlled spray arc (PCS) is a revolutionary solution for heavy fabrication processes that eliminates the concerns associated with short circuit or globular transfer. The PCS system operates by utilizing a pulsed arc that moves through the globular range before seamlessly transitioning to a spray arc. This unique approach ensures a highly stable and efficient spraying process without any disruptions or inconsistencies. One of the key advantages of PCS is its ability to provide precise control over the arc width. This is achieved through a pulse correction feature that allows operators to adjust and fine-tune the width of the arc according to their specific requirements. Unlike a conventional constant voltage (CV) spray arc, which lacks this level of control, PCS enables users to achieve the desired spray pattern with exceptional accuracy and repeatability.

      By combining the benefits of pulsed and spray arcs, the PCS system delivers exceptional performance and versatility in heavy fabrication applications. It not only eliminates the challenges associated with short circuit or globular transfer but also provides the flexibility to achieve precise and consistent results.
