Welding machine – usage method
1. Preparation
- Choose the right welding machine (arc/MMA, MIG, TIG, etc.) based on the job.
- Wear safety gear: welding helmet, gloves, apron, safety shoes.
- Clean the metal surfaces to remove rust, oil, paint, or dirt.
- Select the correct electrode or wire and set the proper current (amps).
2. Setting up the machine
- Connect the power supply properly.
- Fix the ground (earth) clamp securely to the workpiece.
- Insert the electrode or welding wire into the holder/torch.
- Adjust current and voltage according to material thickness.
3. Welding process
- Hold the electrode/torch at the correct angle (about 15–30°).
- Maintain a proper arc length (not too close or too far).
- Move steadily along the joint to form a smooth weld bead.
- Avoid sudden movements to prevent weak joints.
4. After welding
- Allow the weld to cool naturally.
- Remove slag (for arc welding) using a chipping hammer.
- Inspect the weld for cracks, porosity, or weak spots.
Benefits of using a welding machine
- Strong and permanent joints – much stronger than bolts or rivets.
- Versatile – works on steel, stainless steel, aluminum, and more.
- Cost-effective – reduces material waste and repair costs.
- Time-saving – faster joining compared to mechanical methods.
- Durable results – resistant to vibration, pressure, and heat.
- Wide applications – construction, automotive, shipbuilding, furniture, repairs.
