Vertical-up flux-core, unlearning downhand habits
23 V · 330 ipm · DCEP
Preheat: None
How it went: Best vertical-up bead yet — slag stayed behind the puddle the whole way. The 1 V drop made the difference; keep 23 V / 330 ipm for 1/4 in.

Eight sample sessions with full machine setups, preheat and interpass temps, and outcome notes. Filter, search, and sort them right here — everything runs on sample data.
Each entry records one session’s full setup — process, machine settings, consumables, preheat and interpass temps — plus how it went and what to change next time, so known-good settings are never lost. AI analyses are separate but can link to an entry; the analyze wizard saves one from your submitted settings by default.

26 V · 480 ipm · DCEP · 2 passes
Preheat: 150 °F with a rosebud · Interpass: 300 °F max, verified before the second pass
How it went: 26 V / 480 ipm is the keeper setting for this machine and gas. Logged so I can dial it back in without the half-hour of test beads.
95 A · DCEP · 3 passes
Preheat: None · Interpass: Kept under 300 °F between passes
How it went: Cap still picked up undercut on the left toe. Next session: drop to 90 A for the cap and pause longer on the toes during the weave.
26 V · 400 ipm · DCEP · 3 passes
Preheat: 50 °F shop ambient · Interpass: Under 350 °F, checked with a temp stick
How it went: Cleanest stack so far — no visible slag lines at the toes. Keep the interpass temp-stick habit; it made pass placement easier to read.
130 A · AC
Preheat: None
How it went: Puddle still slow to wet in at the start. Next session: preflow a touch longer and try 135 A for the first inch, then back off.
19 V · 280 ipm · DCEP
Preheat: None
How it went: Chart settings ran hot for this fit-up — ripple washed out near the stop. Try 18 V / 260 ipm next time and watch the gun angle in the last two inches.
78 A · DCEP
Preheat: None
How it went: Keyhole got away from me in the last third. Try 75 A and a shorter pause next time, and check the root gap with a spacer before tacking.
58 A · DCEN
Preheat: None — thin wall
How it went: Width held steady until the tube curved away — lost the cup rhythm twice. Cut the next set of coupons shorter and reposition more often.
