I am finally breaking down and ordering a box of ER70-2. My local welding store does not carry anything else (and often doesn't bother to stock ER70-2!). I wonder if I should get a small quantity of ER70-6. Will it make much of a difference on the odd occasion when I have to weld something dirty.
Also, does silicon bronze come in .045--sizes less than 1/16? I have some thin stainless to work on.
