CE Marking
CE Marking on a product is a manufacturer's declaration that the product complies with the essential requirements of the relevant European health, safety and environmental protection legislation, in practice by many of the so-called Product Directives.
C250 Lead Free Soldering MachineProduct Features & Benefits

C250 Wave Soldering Systems feature a high-efficiency, low-volume solder pot and corrosion-resistant wave pumping system. Developed in conjunction with some of our closest customers, the initial start-up cost for solder when using the C250 is approximately two-thirds to half the cost of competitive equipment. Our high-efficiency heaters and small, 100 kg (220 lb.) volume considerably decrease start-up time and consume much less energy, but more importantly reduce oxidation and dross formation. The specially-coated, solid cast-iron solder pot has a seamless construction and includes a three-year replacement warranty. The solder pot and wave assembly easily slide out from the rear of the unit onto an extendable platform and are braced by heavy-duty supporting legs during loading and maintenance
The C250 is supplied as standard in a single-wave configuration for conventional through-hole assemblies, but for minimal additional cost can also be supplied as a dual-wave system for surface mount and mixed technology boards. Dual-wave technology often provides improved hole penetration and reduced bridging on difficult-to-solder boards of all technologies and therefore makes the dual-wave configuration very popular. If necessary, the chip wave in dual-wave systems can easily be deactivated through the installation of a nozzle cover plate included with this option. Wave height control is dial-adjustable to a maximum height setting of 10 mm (.39") and the wave pump motor, with on/off control activated by optical board sensors on the conveyor, is also protected by low temperature and overheat alarms.
The C250 Wave Soldering System includes a high-temperature, corrosion-resistant, fiber-finger conveyor system with variable speed up to 2 m/min (79"/min). Conveyor angle (3°-6°) and width are easily-adjustable to accommodate PCBs from 30 mm to 250 mm (1.2" to 10"). A chain-driven, pin-type inlet conveyor is included as standard and allows easy loading of assemblies and smooth transfer into the conveyor fingers.
After flux application, a 420 mm IR preheater uses stainless-steel sheath-type heaters to raise PCBs and components to manufacturers' recommended temperatures for proper activation of VOC-Free and Lead-Free fluxes.
A reliable, easy-to-use foam fluxing system is included with the standard C250 and provides extremely consistent, maintenance-free performance over extended periods. For assemblers looking for even greater precision, the C250 can also be purchased with our optional "drum-spray" fluxing system. Drum-Spray Fluxing Technology is designed to deliver the precision of spray fluxing through a simple, innovative design that is easier to set up and maintain, and less costly to operate than other spraying methods. As shown in the diagram below, the Drum-Spray nozzle is positioned as close to the bottom of the PCB as possible and precisely applies flux in a thin vertical knife pattern across the full width of the board as it passes over the rotating drum. This method has been shown to provide more uniform application and less flux waste than systems that utilize small nozzles mounted to a reciprocating motor drive below the PCB. An adjustable mask is used to control the width of the spray pattern and optical sensors provide on/off control of the spray mechanism.
C250 Series wave solder machine is available with dual waves for mixed technology (through-hole + SMT) processing or with a single wave for through-hole only. Stand is included. It has everything you need to get started with lead-free solders: high-temp finger conveyor, foam fluxer, 16.5" of preheating power, high-temp solder pot, built-in controls, and stand.
An upgrade to spray fluxer and touch-screen computer control is also available.

Finger conveyor eliminates the expense and time cost of using pallets and will not wear out from the high temperatures required for lead-free solders. Heating coils and cast, high-temperature solder pot also visible. | A rear panel drops open, allowing the supporting legs, shown folded for storage (L), to deploy, allowing the panel to open for convenient and easy access to the high-temperature cast solder pot. | |

Turning the removable handle (L) manually controls the position of the solder pot once the rear door is opened, allowing easy access for cleaning and maintenance. | The finger conveyor (R, inlet with the adjust handle below), accepts differing board widths. It can be easily raised or lowered by means of the manual wheel under the rail (L) at the other end. |
