This image highlights the adjustable wire feed speed control, showing a knob with settings from 1 to 10. This allows for precise control over the wire feeding rate, crucial for optimal weld quality.

4.3 Welding Techniques

Proper technique is crucial for quality welds. Practice on scrap material before welding on your project.

• MIG/FCAW: Maintain a consistent stick-out, travel speed, and work angle. Use a push or pull technique depending on the application.
• MMA: Maintain a consistent arc length and travel speed. Use a slight weaving motion for wider beads.
• Lift TIG: Initiate the arc by touching the tungsten to the workpiece and quickly lifting it. Maintain a short arc length and feed filler rod manually.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your welding machine.
