MOTOWELD INPUT UNDER-VOLTAGE indicates input voltage is too low, possibly due to environmental conditions or filter issues. The manual's first action is: “(1)Check the ambient temperature (40 degrees centigrade or less) and operational ratio (60%). (2) Check if there are dust, dirt, and clogging on the dust protective filter. Clean or replace the dust protective filter if necessary. (3)In case of RL350, Check the thermal guard (Item No.318).”
