Which of these does the welding tool release ? 1) heat and electrical energy 2) heat and light . I think it's heat and light is this correct .

What kind of a welding tool? I agree if it's the welding torch.

Yes, you are correct. Welding tools typically release both heat and light during the welding process. The intense heat is used to melt and fuse metals together, and the light is a byproduct of the high temperature generated. Welding also involves the use of electricity to create an electric arc, which produces the heat and light energy required for the process. So, option 2) heat and light is the correct answer.
