Manual Welding

Our range of welding power sources, wire feeders, torches, and other components ensures consistently pristine welds with every operation. Additionally, they come with our One Source guarantee, meaning that we manufacture all these components. Consequently, when you require service or support, you only need to reach out to a single company.

The “Hot Start” function in a welding machine is employed to facilitate and enhance the initial welding process. This feature ensures increased power and voltage during the welding ignition, aiding in easier electrode ignition and the establishment of a stable arc.

When the “Hot Start” function is activated, the welding machine temporarily amplifies the output voltage or power at the commencement of the welding process. This is typically necessary for welding materials that encounter challenges in arc ignition, such as thick materials, dirty or rusty electrodes, or materials with an oxidized coating.

The initial high current or voltage provided by the “Hot Start” feature aids in removing the oxide layer on the material’s surface and swiftly establishing and maintaining a stable arc. This allows the electrode to heat rapidly, facilitating material melting with fewer complications.

Once the arc is established and stable, the “Hot Start” feature is generally disabled, and welding continues at the conventional output power or voltage setting. The utilization of the “Hot Start” function depends on the type of welding and materials, as well as the specific requirements of the welding procedure.

ARC FORCE is a welding machine feature that enhances arc stability and control. It automatically adjusts electric current, ensuring a stable arc, even with changes in welding conditions. This function is especially helpful for electrodes with long arcs, preventing spattering and providing control over penetration depth. Some machines allow customizable ARC FORCE levels for quicker or more gradual adjustments. It’s a valuable tool for welders, improving welding quality and reducing errors.

Wave Pulse is a feature that extends the range of operation by utilizing an AC/DC pulse (0.5-32 Hz). In the AC/MIG welding process, the new Wave Pulse feature regularly regulates control over the welding current, wire feed speed, and monitors the melting during welding.


Advantages of the Wave Pulse feature:

  • Reduction in the formation of gas bubbles.
  • Optimized gap bridging.
  • Ability to create a weld bead with similar scalablility to TIG welding.
  • Effective gap bridging and an excellent weld appearance.


Furthermore, by using the OTC Wave Pulse feature, a weld appearance similar to TIG welding can be achieved. The benefits of this feature include:

  • Minimal porosity formation.
  • Outstanding gap bridging.
  • Controlled heat input.
  • Weld appearance resembling TIG welding.
