Tool
Welder
- model: xxx
- consumables: xxx
- work envelope: xxx
- manual: xxx
- photo: 100px
- North Forge Fabrication Lab: No
Torch
Torch is a Weldcraft A-150 (WP-17).
Electrodes
Two most common
- Thoriated (red) is what somewhere online recommended for brazing; radioactive, though...
- Ceriated (grey, used to be orange) is what Lawrence recommends for AC and DC; for lower amperage precision work
Cup etc
Parameters
Polarity
- Negative side is colder so usually the tool [1]
- Positive makes for shallower, wider affected area [2]
AC vs DC
- AC to bust oxides; pretty much always for Aluminum, also for some brass
Current
- setting rule of thumb: 45A/mm thickness DC, 40A/mm thickness AC in Aluminum[3]
- actual voltage potential is function of arc length, higher when longer, so needs to be kept consistent
Gas flow
Tip shape
- blunter for AC
- blunter will not go as deep
Joint typws
- square butt joints up to 6mm steel can be butt?
- Flange (Boerdelstoss) where the edge is bent up slightly and used as filler
