ENERGY MODE
This mode developed for welding with energy control framed by a DMOS allows, in addition to the energy display of the bead after welding, to set:
- The thermal coefficient according to the standard used: 1 for ASME standards and 0.6 (TIG) or 0.8 (MMA) for European standards. The displayed
energy is calculated by taking this coefficient into account.
- The length of the weld seam (OFF - mm): if a length is recorded, then the energy display is no longer in joule, but in joule / mm (the unit on the
display «J» flashes).
WELDING CYCLES
Standard 2T process:
Dstart
Soft-start
When the trigger is pulled, the Pre-gas starts. When the wire comes into contact with the metal, a pulse ignites the arc and the welding cycle starts.
When the trigger is released, the feeding stops and a current pulse cuts the wire properly followed by the Post gas. While the Post gas is still going,
pulling the trigger allows to quickly restart the weld (manual chain point) without going through the HotStart phase. A HotStart and/or Crater filler
can be added to the cycle.
