19-6 FF Makeover

[BradleyD]

It's a Lincoln Invertec. I used TIG all the way. If you want an anodized top a MIG gun won't work. The wire will literally bounce off the material since the anodized coating doesn't conduct electricity and can't arc correctly. Using TIG you will have to have a high frequency start. Even though it's the same material anodized aluminum welds very differently than mill finish.

The invertec has built in HF start?

Yes, most of your late model AC/DC inverters should have a built-in HF. If you're looking to get a new machine take a good look at the Thermal-Arcs too. I can't say anything bad about my Lincoln but the Thermal-Arcs are as equally good, or better, at a much better price point.
