Depth, Wall angle, Root gap to match the joint. Do this first — changing the groove clears all passes.
Dial Voltage and WFS like at the machine — current follows WFS through the
burn-off law (watch the A / kW / kJ/mm pills; longer stickout = less current).
Leave synergic pulse ticked: spray-like transfer with the penetration finger at any WFS.
Untick it only to simulate a CV machine's short-arc / globular / spray map.
Travel speed sets the bead size and becomes that pass's job speed. Work angle points the arc — the fusion digs where the torch points, so angle into the bevel on fill passes or the wall only gets a thin film (LOF). Travel angle: drag (+) digs deeper, push (−) lays flatter and wider. Aim with Torch position or click the section.
Interpass temperature plus heat accumulation give each bead a substrate temperature (readout in the card). Hot groove → flatter, wider beads and fewer passes; ≥300 °C raises the slump flag. Set accumulation to 0 if you cool to interpass before every pass.
Dashed bead + red dashed burn-in show the next pass live: penetration with its ±95 % process-noise band, dilution, the KTH reference number, and the flag chips. Set your Target penetration and keep P[pen ≥ target] ≥ 90 % — a set-up that only averages the target misses it half the time.
Deposit next ▸ or Auto-fill ▸▸. Every bead freezes its full arc + torch + thermal snapshot — change settings between passes to weld root, fills and caps differently. The blue dashed line through each bead is the torch axis it was welded with, down to its fusion bottom.
Course grouping bins beads into layers (lower = more, thinner courses); the
L1…Ln labels at the left edge show each course's height and bead count. If the auto
grouping gets it wrong: 🖇 Course — click any bead or L-label (the whole course
highlights), then click the course it belongs to. 📌 Bead — click one bead, then its
new layer; click the same bead twice to pop it out into its own layer. Pinned beads
carry a small blue ring; Clear resets all manual edits. Set Cap courses and root hand-welded, then

Physics tuning card: arc efficiency, penetration / wetting / thermal-wetting gains. Current anchor: 337 A / 30 V / 45 cm/min → 4.0 mm centre depth. The numbers are planning aids — COMARC still finds the real joint on the day.
