How thick are the model 4 side tubes? Wide body kit welding

[rogerh12]

I will be adding the williams wide body kit to my model-4-1200, using the Tig Spot weld kit, by Eastwood, to keep the heat down. But, I need to know how thick the side tubes are on the kitfox, so I can set my DC current to the right level, and get a good spot weld. Anyone know the wall thickness, as shown attached here?

That was my guess, but i figured someone would know for sure.
Hope to have mine welded up shortly.

If you've got any welding experience 4130 welds like a dream compared to some of the other alloys. You shouldn't have any issues.
