TIG AC/DC 270 A · three-phase 400 V
Power-source reference only. The manual labels these ratings TIG; they are not split into separate AC and DC tables. Torch AC duty is a separate limit: specify torch, cooling, cables and package for the required current. These ratings do not describe MMA duty or establish a material-thickness capacity.
