What can be done to prevent the weld bead becoming too built up when restarting a weld?
A) Tapering the weld down before stopping to make the restart more even.
B) Start the next weld slightly in front of the ending point of the last weld.
C) Make an electrode change before the rod gets too short so you see the weld better.
D) Use a long arc on the starting electrode and hold the arc in one place so it melts the buildup down before restarting the weld.

Starting the next weld slightly in front of the ending point of the last weld will prevent the weld bead from becoming too built up. Tapering the weld down before stopping can also help, but it may not always be practical or possible. Changing the electrode before it gets too short or using a long arc on the starting electrode may actually contribute to a larger buildup on the restart.
