Aufhauser runs a nine minute weld test on a representative sample of every pallet produced.
We test and record the feeding force required to push the wire through a 15 foot MIG gun. We also test for the number of shorts per second. (The more dirt on the wire the more shorts.) The sample rate for the data is 100 data points per second.

Below is a benchmark comparison between Alcotec 4043 and Aufhauser Aluminum 4043.
Both wires had good shorts (good means below 1.0). The feeding force was the big difference when you look at the two graphs. Our wire feeds significantly better than Alcotec's.
