I have a 110v miller Mig.

General welding I get and am fairly good at considering I just started but it's learning curve.

The Spot weld kid isn't too helpful where you can't get the pliers onto the seam. BUT IT's a cool thing to consider getting.

The hint about turning the heat up might help. I"m going to try that. Plus screws in places you can't reach.

Overall thanks for the info.

for the record when i had that problem with my cargo floor i did ;
- raised the heat, alot. I went from A (lowest setting) to C (medium one)
- raised the wire feed, alot too. To get a good pool, you need alot of wire. On a scale of 1 to 8 i believe, i was at 5.
- Screw helped alot. When there was a lip, i used standard pince grip to hold it as close as possible near what i was welding.
- used 1/4 hole. It was the smallest i could go. Smaller than that it felt like the pool didnt get hot enough to get good penetration.
-as Eric&Barb advice, using a wet rag over weld helped cooling down faster and avoid wave and/or weld popping.

If it can help you, a thread where i got help on body forum ;

Good luck. If you just aim for something solid and not too pretty, welding is actually fun to learn.
