Welding Tips and Tricks

I have never used 707 rod but have access to some and was wondering if it is worth bringing home a handful. I looked it up and it sounds like a good all around rod. Any thoughts?.....also thoughts on royal 220. thanks

I have used the Crown line of products and have never had a problem. Hope the PDF helps. As for the 707 rod, that is a good rod for joining dissimilar metals. If you can get some. especially for free, I would pick it up.
