Just about to deploy the new TIG on some 4130 tube for the 1st time. Making a simple soft pannier rack for a friend's XT250 out of 5/8 dia .065 wall tube. The design should be plenty strong even if my welds aren't 100% but it's always nice to do stuff right. I will practice a bunch before starting on the job. I've built a couple of similar racks that have worked well but have had a mate do the actual tube welding as we didn't have the gear then.

The key joints will be where the tube is butted against the mild steel bushes I have machined up for mounting points. Will common garden ER70S-2 filler do the job ok? Post heat to cherry red with the torch for max awesomeness? Any other tips for the tube welding n00b?

Cheers
Clint
