I have myself a HarbourFreight 140 stick welder, cost me about $100US. I know, its all I got so I must do with it, for now.
Anyhow, I am looking for comments on my first rod of 7018, running at100Amps. I have been making a few passes with 6011 at around 85Amps or so and decided to try 7018. Wow, this is a nice rod to weld with.
I had some scrap 4" channel laying around, I ground down the edges to a bevel and clamped the two pieces together. I struck up the 7018 rod and produced the weld in the link:
If you look at the left edge, this is where I tacked it together, I ended the weld at this joint.
