Welding technology

Welding processes

  • MIG / MAG conventional

The FOCUS.ARC further significantly extends the range of applications for the welder

  • Reliable root formation 
  • particularly deep fusion penetration
  • Reduced undercuts 
  • Less seam preparation
  • Welding with a short, powerful arc

The strongly focused arc significantly changes the deep fusion penetration conditions, whereby the weld seam opening angle is reduced and new types of weld seam geometries can be created whilst maintaining process reliability.

SDI®-Plus – dynamic in a new dimension

The SDI®-Plus controller is now effective over the entire arc range. Also for a spray arc. SDI®-Plus offers completely new possibilities to precisely adjust the arc to the most diverse requirements.

The targeted modelling of the arc enables properties such as heat input, gap bridging and penetration to be perfectly adjusted in the simplest way. Whether in the conventional process or the FOCUS.ARC process. A control dial is sufficient to open completely new dimensions.

Changing the heat input using SDI®-Plus:

  • The heat input is simply controlled to best match the requirements without the need for a special procedure
  • SDI®-Plus optimizes penetration and root formation
  • The heat input can be reduced by as much as the task requires
  • Welding in the most difficult welding positions becomes safer and easier with SDI®-Plus

All the advantages of the MEGA.ARC² at a glance

Highlights: Two different variants of feed cases are available for the MEGA.ARC2 range: the feed case MEGA.ARC2 is available for the complete range and the portable feed case CONSTRUCTION is available for MEGA.ARC2 350-4 WS and MEGA.ARC2 450-4 WS.

Interval welding is defined as spot welding with defined breaks. Advantages: Application of the thinnest quantity of filler materials, reduction of unwanted heat input into the base material.

Feed case: The electronically controlled 4-roller wire feed unit ensures that the wire is always conveyed evenly and precisely.

Interval welding: The standard 17-pin remote control socket provides an interface with start/stop and current-flow signals as well as with analog inputs for energy and wire correction enabling mechanisation.

Uniform wire feed: The new MEGA-ARC2 is equipped with an integrated job memory as standard. 4 machine settings can be stored per characteristic curve.

Integrated automation interface: Units from the MEGA.ARC2 range are particularly robust and well thought-out and are especially suitable for demanding industrial applications when welding thin or thick sheets of steel, stainless steel or aluminium.
