C245 cartridges provide 140W peak power and excellent thermal recovery, making them the versatile choice for hobbyists handling through-hole components, larger SMD work, and general electronics soldering across the UK.
Why C245 Cartridges Suit General-Purpose Soldering
The C245 cartridge design combines a high-power heating element with an integrated temperature sensor in a robust package. This construction delivers rapid heat-up in approximately two to three seconds and maintains stable temperatures even when soldering to ground planes or large thermal masses.
With 140W peak power and an operating range of 150–450°C, C245 cartridges handle tasks that smaller cartridges struggle with. The additional thermal capacity means less waiting between joints and more consistent results across varied component sizes.
Hobbyists appreciate the balance between precision and power. C245 cartridges work equally well on SOIC packages and chunky through-hole connectors, reducing the need to switch equipment mid-project.
Recommended Soldering Stations for C245 Cartridges
C245 cartridges require a compatible station with T245 handle support to deliver their full 140W performance potential. The station controls temperature accuracy, heat recovery speed, and overall soldering experience.
For hobbyists, a quality JBC-compatible station provides the precise temperature feedback C245 cartridges need. Look for stations with digital temperature display, adjustable settings across the full 150–450°C range, and stable power delivery.
C245 cartridges fit YIHUA soldering stations including the YIHUA 982, 982-III, 982D, 992D-II, and 982D-III models. These stations provide the power output and temperature control C245 cartridges require for optimal performance.
Dual-handle stations offer additional flexibility, allowing you to switch between C245 cartridges for general work and C210 cartridges for precision micro-soldering without changing equipment.

C245 vs C210: Choosing the Right Cartridge
Both cartridge types serve distinct purposes in a hobbyist setup.
C210 cartridges deliver 40W and excel at micro-soldering tasks: fine-pitch SMD components, 0402 packages, and densely populated boards where precision outweighs thermal demand.
C245 cartridges deliver 140W and handle larger work: through-hole components, wire connections, ground planes, and components requiring sustained heat. The larger tip profiles transfer energy more efficiently to bigger joints.
Many hobbyists start with C245 cartridges for general work, then add C210 cartridges when projects demand ultra-fine precision. Together, they cover virtually all electronics soldering requirements.
C245 Tip Profiles Available
Each tip geometry addresses specific soldering challenges. Selecting the appropriate profile improves efficiency and joint quality.
C245-I (Conical)
The conical profile tapers to a fine point, suitable for precision work on smaller SMD components and accessing individual pins. While C245 cartridges are larger than C210, the conical tip still provides good accuracy for detailed tasks requiring more thermal power.
C245-SI (Bent Conical)
The bent conical profile features a 30-degree angle near the tip, allowing vertical access to hidden leads and awkward angles. This geometry proves invaluable when components or board features obstruct straight approaches. Ideal for rework situations and tight spaces where standard tips cannot reach.
C245-2.5K (Knife 2.5mm)
The 2.5mm knife profile offers a compact chisel edge for drag soldering fine-pitch integrated circuits and removing solder bridges. This width balances precision with adequate thermal mass for consistent heat transfer across multiple pins.
C245-3.2K (Knife 3.2mm)
The 3.2mm knife profile provides a mid-range option for general SMD and through-hole work. It handles SOIC packages, small connectors, and standard pitch components efficiently. Many hobbyists find this width covers the majority of their soldering tasks.
C245-4.7K (Knife 4.7mm)
The 4.7mm knife profile delivers maximum heat transfer for larger through-hole components, wire tinning, and joints connected to ground planes. The wider contact surface reduces soldering time on thermally demanding connections.
Common Applications for Hobbyists
C245 cartridges serve as the primary tool for numerous hobbyist projects.
Through-Hole Component Soldering
Traditional components with wire leads require efficient heat transfer to both the lead and pad simultaneously. C245 knife tips excel at this fundamental soldering task, producing reliable joints quickly.
Wire and Cable Work
Tinning wire ends, soldering to terminal blocks, and attaching connectors all benefit from the thermal capacity C245 cartridges provide. Larger wires that would cool smaller tips remain workable throughout the joint.
Ground Plane Connections
Multi-layer PCBs often feature ground planes that absorb heat rapidly. The 140W power rating ensures C245 cartridges maintain working temperature when soldering to these thermally challenging areas.
General Electronics Projects
From amplifier builds to power supply assemblies, C245 cartridges handle the varied component sizes typical of hobbyist electronics. One cartridge type manages most joints without swapping equipment.
PCB Assembly and Rework
Populating new boards and replacing faulty components both require consistent heat delivery. C245 cartridges provide the thermal stability needed for quality results across extended work sessions.
Temperature Guidelines for Best Results
Correct temperature selection ensures strong joints without component damage.
For leaded solder, set the station between 280–320°C. Lead-free solder requires higher temperatures, typically 320–380°C. Heavy thermal loads such as ground plane connections may need temperatures approaching 400°C.
Precision work on smaller components benefits from the lower end of these ranges. Larger joints and thermally demanding connections require higher settings.
Allow the cartridge to stabilise at target temperature before beginning work. Clean and tin the tip before each session to maintain efficient heat transfer.
Compatibility with JBC-Style Stations
C245 cartridges use a standardised five-pin connection that fits T245 handles and compatible soldering stations. The cartridge connects via heater element, thermocouple, and ground pins, enabling precise temperature feedback and control.
Quality alternative cartridges maintain the same resistance specification (approximately 5.5–5.7Ω for standard models) and dimensional tolerances as original equipment. This ensures reliable performance and accurate temperature readings across compatible stations.
The T245 handle accommodates hot-swapping, allowing quick tip changes without waiting for cool-down. This feature speeds workflow when projects require multiple tip profiles.
Maintaining Your C245 Cartridges
Proper maintenance extends cartridge lifespan and ensures consistent performance.
Clean the tip on brass wool at 250–300°C rather than wet sponges to avoid thermal shock. Apply fresh solder immediately after cleaning to maintain the protective tinned surface. When pausing work, reduce temperature rather than leaving the cartridge at full operating temperature.
Avoid abrasive cleaning tools or chemical tip cleaners, which damage the protective plating. Store cartridges in a dry environment when not in use to prevent oxidation.
Inspect tips regularly for signs of wear, oxidation, or pitting. A well-maintained cartridge provides years of reliable service for hobbyist applications.
What to Consider When Choosing C245 Cartridges
Quality alternative cartridges deliver excellent value for hobbyists. They provide reliable performance at a fraction of original equipment cost, making versatile soldering accessible to more users.
Look for cartridges with consistent tip geometry, proper resistance values, and good thermal conductivity. These factors determine real-world soldering performance.
For a versatile starting kit, the C245-3.2K knife tip handles most general tasks. Add the C245-SI bent conical for awkward angles and the C245-4.7K for heavy-duty work as your projects demand.
