Workshop calculator
Current range, heat input, preheat, electrode consumption and job cost. Works without a signal once opened.
ESAB: Ø2.5 for 3–6 mm, Ø3.2 for 6–12 mm, Ø4.0 for 12–25 mm.
Datasheet range
60–100 A
PF: about 10% lower (ESAB). PE: about 15% lower (Miller). For PC and PG the sources give no rule, so start at the low end and test on scrap.
From manufacturer datasheets for carbon steel. The datasheet supplied with your batch decides.
