What size spot weld cutter do you use? What size hole do you drill in a new repro panel to give a look of spot welds when filled with the mig?
I use 3/8 cutters mostly, as I find the smaller ones don't separate as clean. The larger cutters don't last more than a handfull of welds. Best ones are the cheapies on ebay from jim at kestors services, eBay Member: ksjimmyk, they last just as long as my $40 zebra bits...but cost next to nothing.. and he sharpens them when they are worn. Size the new hole according to the size of weld you want to create, it takes practice to get a plug to look like a spot, most guys will just grind them flush and use an eraser in the wet primer to simulate a spot weld. Works great! I cheat.. I use a spot welder to recreate spot welds!

I was using the less costly (didnt know there was an alternative at the time) spot weld cutters for quite some time until I discovered the Blair 11094 spot weld cutter. The 11000 series Blair will cut spot welds in a fraction of the time it takes with the older double ended type cutter. I was so impressed with the 11094 I gathered up all of my other spot weld cutters (some of which the blades were unused) and promptly pitched them in the scrap metal container. Best of all- MADE IN THE USA Blair See cutter at upper left side of page.

I use only Blair Rotobroaches here. They last the longest and I get hundreds of cuts out of one blade. Correct speed and lubrication is the key.
Primarily 5/16 and 3/8 cutters
The other alternative is a plasma cutter set to cut the first layer of material. Works really good and much faster/cleaner than anything else.

Wow never seen that done. My plasma is not adjustable, can you tell us more? I have more welds to cut on my current project.
I used all of them over the years, I think of the roto broach as being the most durable. But I still wound up using a reg drill bit and think it works and lasts the best. I can resharpen a drill bit in seconds.

Spotweld cutters are only needed when you want to re-use the outer panel.If you are tossing the outer panel,then just use a zip disc to "erase" the spotweld until the two panels pop loose.This way there is less work involved,and less damage to the lower panel.
If you use a spotweld cutter,you will still need to grind off the button that is left over,plus spotweld cutters are way to easy to go too deep and cut into the lower panel that should not be harmed.
I have been doing panel replacement daily for almost 25 years,and this is by far the quickest and simplest method

What is a zip disc and where do you buy it?
A zip disc is another name for a cutoff disc.The 3" diameter abrasive cutoff discs that fit on a handheld cutoff saw.Use the thicker version rather than the thinnest,or double up two thin ones if that is all you can find.The thin ones are very thin-about 1/32" I guess,and can be flexed somewhat with your fingers,the thicker ones are about 1/16".
