I hope you can help me by code or link

Thank you very much for your reply
Indeed, I need welding effect, I mean when you watched the youtube link, you can notice when the rode closed to plate, the welding effect appair, a light similar to the fire and welding effect appair, the positon translate, and the welding increase linearly.
So , becuase I am abeginner I would be most thankful if you kindly give me a link to how can draw this effect, I need how can draw welding effect only.
Thank you and looking for your reply
