Abstract

Quick-reference selection matrix. Match customer requirements to specific models in under 60 seconds.

By Diameter

| Customer Requirement | Recommended Models | |------------|-----------| | ≤25mm (ultra-fine) | G25 Capillary | | 25–40mm | G40 Capillary | | 40–90mm | G90C / G90CL / G90K / G90Z | | 90–120mm | G120C / G120CL / G120K / G120D / G120C-V12 | | 120–170mm | G170C / G170CL / G170K / G170D | | 170–240mm | G240C / G240CL / G240K / G240P | | 240–290mm | G290C | | 290–350mm | G350C (Triple-Chuck) | | ≥240mm high-performance | G240 MAX |

By Function

| Customer Need | Series | Why | |---------|---------|------| | Basic cutting, no special requirements | C Series | Side-load standard. Best value. | | Save material (expensive alloys) | CL Series | Zero Tailing. <20mm remnant. | | Weld-ready bevels | K Series | 5-Axis. ±45°. One pass. | | No CAD, quick start | F/H Series | No-Drawing. Input parameters. Cut. | | High-volume production line | Full Auto P / Full Auto C | Auto-load. Minimize labor. | | Precision micro-tubes | G25 / G40 | Capillary dedicated machines. | | Oversized engineering | G240 MAX / G350C | Large-diameter specialist. |

By Power

| Material / Wall Scenario | Recommended Power | |-------------|---------| | Standard carbon/stainless, wall ≤8mm | 3000W Standard | | Thick stainless (8–16mm) or ≥240mm large tube | 6000W | | Copper / aluminum (soft metals) | 3000W usually adequate — confirm wall thickness |

Note: 6000W models carry suffix "6000W" — e.g., G240C 6000W, G240K 6000W

By Control System

| Preference | Configuration | |---------|---------| | Existing BCS user, want consistency | All models support BCS standard | | Existing WeiHong user, cost-sensitive | G120C-V12 WeiHong variant | | No preference | Default: BCS (TubesT) |

OBM vs OEM

| Buyer Type | Recommendation | |---------|---------| | End user (own use) | OBM QG Brand | | Distributor (resell) | OEM Neutral (brand as your own) |
