Answer
Brief Explanations:
The tapping method is a common and effective way to strike an arc with a transformer - type DC welding machine. The weaving method is for moving the electrode during welding, not for striking an arc. The short - arc method is a welding technique during the welding process, not for arc - striking. The grounding method is related to electrical safety and not an arc - striking method.
