A duty cycle rating Welders (Specification) is a person who is assigned to the continuity of the benefits of output current.
It is expressed as a percentage of welding time for a period of 10 minutes (which Weld 100% of the time equals 10 minutes) at a specified output current. For example, let us consider the specification: 300A @ 40% duty cycle. A 40% duty cycle is 4 minutes of a period of 10 minutes Welder can operate. For another 6 minutes, the welder must be cooled. If not, Welder will close and more LED light temperature, or Thermal Error code display. If this happens to Weldor (people who weld metal) had to stop production and wait for long to clean up the temperature conditions. The welders are more basic (Transformer / welder SCR based) usually combines two types of bi-metallic strip thermostat (one input Heatsink Rectifier Assembly, and the other at the output Diode Heatsink Assembly). They are wired in series with the current one that is able to open under heat stress. The more advanced welder (welder microprocessor controlled inverter based) usually combines the two thermistors (type Resistor with Negative Temperature Coefficient) to achieve the same result, but a more complex electronic circuits are now engaged to measure the thermal characteristics while being operated Welder.
When the welding specifications are exceeded other than turning off and displays error conditions, internal Fan welder must operate to bring the temperature of the heatsink components to a safe operating temperature. This usually occurs at about 158 degrees F (70 degrees C). This is the maximum tolerable temperature rating for most commercial-grade electronic components. Mounted on a good heatsink (or combination) Rectifier Diodes, the SCR, the IGBT and MOSFET. If the fan stops working or temperature sense circuit failure, these components can be degraded or permanently damaged due to thermal stress.
Must wait to complete the work due to low or specification errors During the temperature is non-productive and frustrating for all parties. This is particularly so when the project deadline, because time is money! When the electronic component failure due to thermal stress anxiety Weldor only increased by a factor of ten. Now Welder totally inoperative until some trouble shooting to do. Once again ... time is money!
When the welding current is determined on a cycle of 100% Weld Output current can be maintained indefinitely, without the need for cold Welder requirements.
Manufacturers publish specifications for their welding Operator Manuals, Service Manual, and Technical Sales Brochures. Unfortunately, Weld output current does not always appear in the ranking of DC 100%. A conversion formula is very useful in situations like this.
To calculate the output current based on the specifications of the cycle using the following formula:
I out = √ [((I x I rated rate) × (DC Spec rate)) ÷ (DC Spec required)]
From the previous example of 300 A DC @ 40%, we can now easily calculate the output current to DC Weld 100%, as follows:
I out = √ [((300 x 300) x (40)) ÷ (100)]
I out = 189.74 Amps.
As you can see, the output current at 100% Duty Cycle is quite a bit smaller than the 300 Amp Welder claimed this. Duty cycle makes a difference!
