The original SA200-F162 had the second-generation Lincoln vacuum idler (R-57). As shown in the image on the right.
Starting with code numbers 3417 through 7242, these were manufactured with the R-57 idler.
Starting with code numbers XXXXX, Lincoln Electric produced its first "PC board idler" system. This was a significant improvement because it allowed the machine to (idle up) when auxiliary power is needed.
The Lincoln system used two reed switches to sense power demand. The image above shows the reed switch on the Lincoln board. The photo to the right shows a generic reed switch assembly. You cannot see the switch; it is inside the black tube.
Have you ever wondered why the Lincoln SA200 has a switch that allows you to disable the automatic idler system, allowing the machine to run at full speed all day? Why do you have to spend more money on gas and wear out your machine faster? It's simple if you are very far from the machine (how far I don't know), the "reed switch" will not sense weld or auxiliary power demand, you have to kill the idler and let it run at full speed, burning more gas (and your money)
You can find electronic idler systems all over the web, cheaper than our system. Why pay more?
Our system comes with a unique Weldmart Centurion idler PC board, backed by a 2-year warranty—plus a lifetime warranty on all hardware.
The system is designed for the owner/operator to install, troubleshoot, and understand the system. We try to help our customers become as technologically self-sufficient as possible.
You want a system that you can depend upon for the rest of your life.
The kit comes with complete instructions and lifetime no charge telephone help.
The Weldmart Centurion is unique in the industry; we have incorporated three LEDs that allow you to see if the board is working. If there is a problem, you can identify it instantly. The green power light says you have 12 volts and a good ground. You would not be; believe how many Lincoln PC board problems we solved by fixing a bad ground (how do you locate a bad ground?).
The board can use the existing reed switch the sensor wires (the red wires).
You can pass a magnet across the top of the "Hall-Effect" black sensor (it has the red wire wrapped in it). The green LED will stay on, the yellow LED and the red LED will come on and the idle solenoid will release.
You can check your idler solenoid by pulling the wire off #4 and touching it to one of the mounting screws. It should spark, and the solenoid should pull in.
The solenoid mount and linkage are stainless steel with SS hardware. All piviot points are SS Shoulder bolts
