Penetration is increased by

1. Increasing welding current and welding speed
2. Increasing welding current and decreasing welding speed
3. Decreasing welding current and welding speed
4. Decreasing welding current and increasing welding speed

Correct Option: B

By increasing the current, large heat is generated and due to lesser speed heat is generated at particular area so that larger penetration can be carried out.
