- Lighting the arc:
The electric arc is lit by rubbing the tip of the electrode on the part that is to be
welded, then quickly retracting the electrode until the arc is maintained.
If the movement is too slow it may cause the electrode to stick to the part, in this
case the electrode may be freed by pulling it to one side; on the other hand, if the
movement is too fast it may extinguish the arc.
- Making the weld:
There are many techniques for making the joints and they vary according to the
operator's requirements. Two classical methods will be studied as an example:
1) butt joint
2) T joint
