So I am welding in the Tangerine Racing inner consol reinforcement. If I have the welder set on three it doesn't bite into the ear. If I have it set on four it bites but it blows holes in the new piece. I was able to get two holes filled and they are definitely welded on. However, I am wanting to know before I do more if going on the four setting will be right and not damage anything. Three just doesn't seem to cut it.

I'm with Panelbilly on this one.
If it's too hot you increase the feed and move faster. If it's too cold you decrease the feed and move slower. The idea is to keep a good arc without burning through. It should sound like frying bacon not snap crackle and pop. You get no penetration on the high amp setting and low feed because you can't keep an arc. The high amp arc burns the wire back to the tip before it gets to the metal. It's a great way to burn up a tip. |

(IMG:style_emoticons/default/agree.gif) I would also add that the distance of the tip to the work is important. Closer and it will burn hotter. Increase the distance and it will be cooler (less penetration) |
