Heavy Duty Type
Heavy Duty Type (Type W) thickens its entire body to increase heat storage and is the best for work needing high heat capacity.
 | Save soldering time. (Refer to Graph 1) A few seconds per 1 point can be cut down. But guess how much time will be saved per 1 day or one month? The efficiency-enhancing effect can be taken. Enable the workpiece temperature to increase. (Refer to Graph 2) If soldering multi-layer board, solder can not be melt due to the insufficient heat. In that case we recommend Heavy Duty Type, which has the larger heat capacity than Standard type, but the same size as Standard. It offers the enough heat capacity that solder can be wet. |
| Heavy Duty Type Only T12 series offers this type. |  |

Measurement conditions
| Measurement method | Solder at 5 points and measure the time until the temperature of the workpiece reaches 250ºC. |
| Board | Paper phenol copper |
| Component | Terminal (External diameter Φ8.5 / Internal diameter Φ4) |
| Tip shape | T12-D12 (Standard) and T12-WD12 (Heavy Duty Type) |

Measurement conditions
| Measurement method | Measure the temperature of the workpiece when 5-point soldering is performed once every 3 seconds. |
