"I just saw the 'Hands On' photo gallery, and I am awed at the work Kevin has done! It's one thing to see the finished product but being able to see how it was built is amazing."

Following the Bubble While MIG Welding

The Voice: Hey, Kevin. What are you getting ready to do?

Kevin Caron: I'm getting ready to weld on one of my contemporary art sculptures.

I had a question on YouTube the other day. A new guy, new welder said the instructor keeps telling him: "Watch the dot. Look for the dot. Watch the spot when you're welding. Look for that dot in the puddle, he keeps telling him: Look right there in the puddle you can see the dot." And he asked me, "What the heck is he talking about? What's the dot?"

Come here. I'll show you.

(Text on screen): Time for a close up . . .


Kevin Caron: See the dot?

The Voice: Yes! I see the dot. It's kind of dancing right behind the molten part.

Kevin Caron: So you could see the little dot. It was about an eighth, maybe a quarter of an inch right up above the tip of the gun. You just keep it at about the same distance and you get a nice-looking weld on your metal. If you go too fast, it gets all ugly.

I've got a lot more to go, so I'll see you guys next time.
