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) |
