Technical Notes
- → Pulse MIG at 130A on 3.7 mm carbon steel — the pulsed arc creates periodic bright/dark cycles, and the dual-exposure merge maintains image stability throughout
- → The higher voltage (21.8 V vs 17 V in short-arc) produces a wider, flatter arc cone — visible in the short exposure as a broader bright region
- → Droplet detachment from the wire tip is visible frame-by-frame — one droplet per pulse peak, cleanly transferred without spatter
Why this recording matters
Pulse MIG on medium-thickness carbon steel reduces spatter and gives better control of heat input compared to short-arc. The pulsed arc creates dark phases that cause image flicker on standard cameras. This recording shows that the dual-exposure merge eliminates that flicker entirely.
