Welding spatter causes consumable wear, torch nozzle clogging, and costly manual post-weld cleanup. DAIHEN's SFT (Spatter Free Technology) provides a proven technological breakthrough.
By monitoring arc voltage micro-fluctuations, SFT detects the liquid bridge formation right before droplet detachment and instantly depresses welding current, allowing the droplet to merge smoothly into the molten pool by surface tension without explosive detachment.
SFT is integrated into the WE series and robotic welding power sources, delivering exceptional slag-free results across automotive BIW, motorcycle frames, and galvanized steel fabrication.
