Weldco would like to thank you for purchasing the MIG160D Inverter Welder. This manual is designed to guide you through using your new machine. Your Weldco inverter welder utilizes the latest in welding technology to ensure you receive professional results in a variety of applications.
Welding poses a variety of hazards to health and safety. Please ensure you have correct safety equipment for yourself and those within the welding area. Your local distributor will be able to assist you with the correct Weldco protective helmet and gloves.
ELECTROMAGNETIC AND RADIO FREQUENCIES – “PACEMAKERS” • Avoid contact with the energized work piece. • Always ensure you have adequate protection from electrocution and burns. • Since the welder owns strong electromagnetic and radio frequencies. Persons fitted with “PACEMAKERS” or similar devices MUST consult their doctor before turning on the welder.
INPUT PLUG The MIG160D is fitted with a 10amp plug. This machine is designed to work with 10amp domestic wall sockets. It is important that the machine is plugged directly into the mains plug. If an extension cord must be used a minimum 2.5mm wire thickness is require and no more than 10m in length.

14. To increase or decrease wire speed, adjust the main adjustment dial (11). To switch to voltage adjustment, press the main adjustment dial (11). Adjust the main adjustment dial to increase or decrease voltage as required. Press the main adjustment dial again to switch back to wire speed adjustment.
5. Polarity Cable Please ensure you have all relevant safety equipment and PPE ready. 1. Connect the optional Weldco Argon Regulator (WDC0812) to the argon cylinder or CO2 cylinder and connect the gas line to the regulator. 2. Connect the gas line from the regulator to the gas inlet (31) 3.

Once the machine has powered up press the welding process selector (13) to select MMA. 19 20 Your Weldco Inverter welder is fitted with a “Voltage Reduction Device” (VRD). The VRD reduces the open circuit voltage to safer levels. The VRD default is OFF.
Failure to do so will reduce your welding performance. Connect the optional Weldco VALVE TIG torch (WDC0818) into the NEGATIVE (3) terminal on the front of the machine. Ensure that the plug is secure in the socket to reduce any chance of arcing from loose connection Connect the optional Weldco Argon Regulator (WDC0812) to the argon cylinder and connect the gas line from the TIG torch to the regulator.
