The first design that to meet our standards for 'electric slurper' with 3 years of associated thought and general design upgrades.
While electric compatible, it is a swing shift design, built for balance and power with sufficient heat retention for torch use.
Optimal accessory: 8-10mm sphere (works as combination valve/pearl)
V1.1 - taller open area, easier to load.
20 vs 25mm - power vs ease of use.
Loading does require precision, but like any specialized tool, skills develop.
