If the wirefeed motor and weld output don't operate when you press the torch trigger on your Tweco Welding System, consider the following: * Check for internal wiring faults from the torch adaptor to the boards. * Allow the unit to cool if the over temperature light is on. * Ensure the power source is set to 'LOCAL', not 'REMOTE'. * Repair any shorted trigger wires inside the torch. * Check and repair faulty trigger wires or the torch switch. * If the issue persists, the Power Inverter board, Control board, or Display board might be faulty and require replacement.
