Step 11Power connections
Lugs were used to make power connections to the 'lyzer, and also 3 stainless steel hose clamps to make a connection to the outer tubes, I dont have a MIG welder and I also didnt want to heat the heck out of the tubes.
I used M6 type power connections seeing as I shouldnt be exceeding the design current of approx 8.5Amps.
Rule of thumb says not to exceed 0.5 amps per in², or face electrode erosion at an accelerated rate. That would equate to 0.0775A per cm², so taking the smallest tube area, the inside of the inner tube which is 111.57cm² X 0.0775A= 8.646A max.
I have seen figures of 0.1A / cm² for 304SS and 0.15A / cm² for 316SS on youtube, but felt more comfortable with figures from long-time experienced experimenters with this technology.
