Go by thickness on chart, not gauge.
Aluminum will spatter using single phase welding.
The above represents a 12” throat depth for gauge sizes shown. For
each additional 6” of Throat Depth, subtract 1 (one) less gauge size. (Ex.
For 16 ga. material, with an increase from 12” to 24” throat depth, is 16
ga. minus 2 gauge sizes = 18 ga. material)
