5.2 Welding Process

• Once the machine is set up for your desired welding process and parameters are adjusted, ensure your workpiece is clean and properly clamped.
• Put on all required PPE.
• Initiate the arc according to the specific welding process (e.g., pulling the trigger for MIG, striking for Stick, or lift-starting for Lift TIG).
• Maintain a consistent travel speed and arc length for optimal weld quality.
• After welding, allow the workpiece to cool before handling.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your RBM2100 welder.

• Cleaning: Periodically clean the internal components of the machine using compressed air to remove dust and debris. Ensure the power is disconnected before cleaning.
• Torch and Cables: Inspect the welding torch, ground clamp, and all cables for wear, damage, or loose connections before each use. Replace damaged parts immediately.
• Contact Tip and Nozzle (MIG): Regularly check and clean the contact tip and nozzle of the MIG torch. Replace the contact tip when it becomes worn or clogged.
• Wire Feed Roller (MIG): Ensure the wire feed roller is clean and free of debris. Verify that the correct groove size is used for your welding wire.
• Electrodes (Stick): Store electrodes in a dry environment to prevent moisture absorption.
