To strike an arc in the manual metal arc welding process, follow these steps:
1. Prepare the welding machine by connecting the electrode holder and work clamp to the appropriate terminals.
2. Select the correct electrode for the job and ensure it is in good condition with a sharp point.
3. Position the workpiece in the desired welding position and secure it in place.
4. Put on appropriate safety gear, including welding gloves, helmet, and protective clothing.
5. Hold the electrode holder in one hand and the work clamp in the other hand.
6. Position the electrode close to the workpiece at a slight angle (around 15-20 degrees) and make contact with the workpiece.
7. Quickly lift the electrode away from the workpiece while simultaneously striking it against the workpiece to create an arc.
8. Once the arc is established, maintain a consistent distance between the electrode and workpiece to ensure a stable arc.
9. Move the electrode along the joint at a steady pace, maintaining the correct arc length and angle to create a strong weld bead.
10. Once the welding is complete, allow the weld to cool before inspecting it for quality.
Refer to the labeled sketch below for a visual representation of the steps involved in striking an arc in manual metal arc welding:

Steps to Strike an Arc in Manual Metal Arc Welding (MMAW):
1. Preparation:
- Wear appropriate safety gear (welding mask, gloves, apron).
- Connect the welding machine to the power supply and ground to the workpiece.
- Select the appropriate electrode for the material being welded.
2. Striking the Arc:
- Hold the electrode holder with the electrode perpendicular to the workpiece.
- Bring the electrode close to the workpiece and tap it lightly to create a spark.
- As the arc ignites, quickly pull the electrode back slightly to maintain a proper arc gap.
3. Maintaining the Arc:
- Keep the electrode at a constant angle to the workpiece (usually 45-60 degrees).
- Maintain a proper arc length (typically 1-2 times the diameter of the electrode).
- Move the electrode smoothly along the weld path.
