During the week I got a new tank of gas, 75% Argon 25% CO2. Today I got it hooked up, did some practice welds, and finally got the patch that was ready last week welding in place. I would say this was my best welding to date. The first welds were making little balls, suggesting poor penetration, so I turned up the current a bit. The trick is to avoid burning through the original sheet metal, which gets pretty thin in places were it was stretched while forming. The edge of the trunk lid is one of those places.
The rest of the day went to the next patch, which will connect to this one to close the large hole beneath the gutter. This one is not curved so much but it does require two bends. Hard to do well without a break. This patch will fit inside and create a foundation for POR-15 Epoxy Filler.
Next Sunday is the Honolulu Marathon, and the shop is closing early. I might have to skip next Sunday altogether.
