Indicators of excessive heat when welding would include:

  1. The arc will not strike

  2. The puddle burns through the metal

  3. The weld warps

  4. Both A and B

The correct answer is: The arc will not strike

Indicators of excessive heat when welding would include the arc not striking. This is a significant sign that the heat level is too high, causing difficulties in initiating the welding process. The statement "The puddle burns through the metal" is more indicative of too high of an amperage rather than too much heat, making it an incorrect choice. Warping of the weld can also occur due to excessive heat, but in this case, the inability to strike the arc is a more direct indicator of excessive heat.
