MIG Welding Techniques and Tips
This section is a bit of a mix. It covers some essential techniques for car bodywork welding, and also some other aspects of DIY welding machines.
Thin Metal
Blowing holes in thin metal? MIG welders aren't well suited to welding steel under 1mm thick.
Here's a technique that should be good for 0.6mm sheet.
Gasless MIG Welding
You can use it in the wind. A page with pros, cons and techniques.
Plug weld
Plug welding is a DIY alternative to spot welding. It's a useful technique in automotive repairs where the panels were originally spot welded.
Finishing Welds
There's only one way to end up with the invisible welded repair and it doesn't involve your ordinary angle grinding disc. This one is a real welding secret.
Welding thick metal
Manufacturers claims of welder capability often seem exaggerated. The Clarke 90EN claims to be capable of welding 4mm steel sheet, but the calculator says 2mm. The page looks into the techniques required to achieve the claimed thickness.

A few random thoughts and techniques that haven't found a home elsewhere in the tutorial.
