MOTOWELD VOLT.DETEC T WIRE ERROR indicates a voltage detection wire issue or incorrect setting of the sensing cable switch to "Base Metal". The manual's first action is: “(1)Check if the voltage detection wire is connected. Check to confirm that the welding voltage sensing cable select switch is set to "Base Metal". The use of MOTOWELD-RP500: Check to confirm that the voltage sensing cable is connected between the base metal and the terminal block TB2 7. The use of MOTOWELD-RL350: Check to confirm that the base metal-side welding voltage sensing cable connects between the base metal and the welding power source via wire feeder cable. (2)Check to confirm that the contact chip and the welding work are not in contact. Cancel the contact if any, and weld them. (3)Temporary power failure may have occurred.”
