Multi-functional Pulse-Heating System

There are a number of assembly applications with temperature sensitive components, which requires the cold soldering iron in the beginning of soldering. It must heat with a certain speed only after touching the component. Pulse soldering system serves this problem.

Pulse system FRC-150 is a low-voltage AC source with digital control that supports one of three hendpieces: Pulse soldering handpiece, Single and Dual circuit Tweezers and Pulse wire Stripper. Power to any of these instruments is fed only during the operation. The tool is in a relatively cold state before and after operation. Power time or the pulse duration and the rate of heating tool is defined by the operator, and then is controlled automatically with digital system. FRC-150 features a Pulse Heat power output that provides controlled temperature ramp-up to reflow temperatures, reducing thermal shock risk and unwanted heating of adjacent solder joints. 

Ability to control a heating rate of contact between room temperature and the soldering is the main difference pulse soldering systems from traditional soldering stations with a constant temperature of the soldering iron. This property specifies the specific area of application of pulse tools to perform operations that are inaccessible to conventional soldering.

Dual-loop pulse Tweezers DIP-65 
Soldering/Desoldering ceramic chip capacitors


Made on ceramic substrate components are very sensitive to sudden changes in temperature. Touching a component with a hot soldering iron without preheating can be fatal to them. Typically, we can use preheaters for heating circuit boards or perform soldering hot air to solve this problem. Much more convenient to use dual-circuit pulse Tweezers in some cases.

Assembly takes cold tool component and pre-set it tinned or coated with solder paste pads on the board. Then operator presses foot switch, and the tool gradually heated to the desire temperature together with the component. Wherein the soldering and power determines the rate of heating and pre-set by the installer may be stored in system memory. You can remove component the same way without any damage.



Wire stripper IS-70
Remove wire insulation


The IS-15 wire Stripper allows rapid, temperature controlled, damage-free removal of all wire insulation including PTFE. A variety of tips are available that are specifically designed for various wire gauges.



Single-loop pulse Tweezers OIP-90
Soldering/Desoldering wires closely to pins


A very simple operation of wiring a cable in a connector also requires specialized tools. If this work is carried out by usual soldering iron, then there is a risk of damage to the insulation surrounding of the wires therefore hot tool. Much faster and more reliable to use single-circuit tweezers. During the soldering current passes directly through the output connector, heating it. When this tip tweezers are a little warm, which ensures safe operation of the instrument to the nearest wires. 

Single-loop tweezers can be converted into Pulse Soldering Iron by replacing tips. Soldering Iron is used in cases where the soldering heat is required at given rate. This is necessary working with ferrite parts where to minimize heating is required. It is also important for restoring printed conductors, where conductive foil cannot be overheated. Handpiece has interchangeable tips of various shapes and sizes and can be used not only for brazing but also for thermal removal of protective coatings.


Digital control 

Pulse system FRC-150 provides automatic selection of the output range depending on the connected instrument. Every time you change the instrument operator presses the corresponding button refer to used tool, and the system automatically sets the minimum and limit the power that the selected tool work. This eliminates overheating and potential damage to a tool tip guarantee an exceptional durability.

Depending on your needs FRC-150 system can operate in one of three modes: "continuous" - heating is carried out with a given power until foot switch is depressed, "timer" mode - work with fixed parameters, and mode "program" - for heating desired program.

Operator sets a power that determines a heating rate for an instrument and a pulse duration - the time during which power is supplied to the instrument for each operation, whether soldering or wire stripping. These parameters are chosen manually one time and then stored in the memory. If operation repeat is needed, it can restore settings by simply pressing a button.

The system provides "Learn" mode for convenience of parameters selection. The first time soldering or wire stripping performed manually with the necessary power. After the end of the soldering operator releases the foot switch and the soldering time will automatically store. Other soldering cycles performed in the "timer" will be accurately the same pre-set time and power.

Seven sets of  time and power values can be stored in one of the seven memory cells of Pulse system FRC-150. Memory cells may be fixed to the selected tool and in result  each of four instruments in cells keeps their values.


Multistage heating

In cases when it is necessary to keep stepping heating or working with solder paste, you can use the "program" mode. This provides automatic changing power level at certain time intervals during one cycle of soldering. Therefore, at each stage operator can change a heating rate. The number of zones with different power levels can be selected from two to seven for each handpiece.


Special power regulator

The system uses a method of periodical load disconnecting from the power supply to the power control. Switching load precisely synchronized and carried out at the time of crossing of zero phase. This method prevents the occurrence of high interference in the supply network, in contrast to the widespread thyristor regulators with phase power control system. Working and non-working periods of load shedding is uniformly distributed in time according to the Brezinhem algorithm. Possibility adjusted from 5% to 100%. Such an adjustment method is best for most technical applications including pulse for soldering stations.
