Process description

Air carbon arc gouging works as follows. An electric arc is generated between the tip of a carbon electrode and the workpiece. The metal becomes molten and a high velocity air jet streams down the electrode to blow it away, thus leaving a clean groove. The process is simple to apply (using the same equipment as MMA welding), has a high metal removal rate, and gouge profile can be closely controlled. Disadvantages are that the air jet causes the molten metal to be ejected over quite a large distance and, because of high currents (up to 2000A) and high air pressures (80 to 100 psi), it can be very noisy.

Application

As air carbon arc gouging does not rely on oxidation it can be applied to a wide range of metals. DC (electrode positive) is normally preferred for steel and stainless steel but AC is more effective for cast iron, copper and nickel alloys. Typical applications include back gouging, removal of surface and internal defects, removal of excess weld metal and preparation of bevel edges for welding.

6. The Wireless Charging Bundle’s cable may be faulty. Try using a different cable.
7. Restart your phone. If the problem persists, please email us at support@anker.com to claim your 18-month warranty. Request sent to owner.

Q: How does the Wireless Charging Bundle charging speed compare to a traditional wired charger?
A: It depends on your device, but wireless charging generally charges at a slower rate.

Q: What is the Wireless Charging Bundle charging speed?
A: Charging speed varies depending on the device. You can expect a maximum charge current of 1A.

Q: What kind of AC adapter should I use with Wireless Charging Bundle?
A: Make sure that the AC adapter that you use has a minimum output of 2A, otherwise your devices may not charge properly.

Q: Can I use a different USB cable instead of the cable that comes with Wireless Charging Bundle?
A: Yes, other Micro USB cables can be used, but to ensure the utmost safety and performance, we strongly recommend using your device’s original cable (OEM) to charge your devices with the Wireless Charging Bundle.

Q: What does Wireless Charging Bundle’s LED indicator show while charging?
A: When the charging pad is powered up, you pick up your phone during charging, or your phone is fully charged, the LED indicator will display blue for 3 seconds before turning off. While your phone is charging, the LED will display a steady blue. If your phone is not charging normally or the temperature is too high, the LED will flash blue. Request sent to owner.

Q: Is radiation from wireless chargers harmful to one’s health?
A: The PowerPort Wireless 5 Pad only emits non-ionizing radiation which is not harmful to humans. What’s more, it’s certified with FCC, CE, RoHS, etc.

Q: Does wireless charging affect other wireless devices?
A: No. Wireless chargers use frequencies between 110-205kHz, which are in a different range than most wireless devices. What’s more, it’s certified with FCC, CE, RoHS, etc.

Q: Does this charger produce excessive heat?
A: When in use, this charger’s temperature should not exceed 104°F/40°C.
