When the ground clamp is connected to the negative terminal during welding, this is known as DC electrode negative polarity. In this setup, electrons flow from the workpiece to the welding machine, creating a hotter arc and deeper penetration. This polarity is commonly used for welding processes that require higher heat input and faster travel speeds.
When a conductor is connected to "ground," it becomes neutral and carries no charge.
A positive charge is built up which then wants to find a path to ground. It can be either polarity. It just depends on how the charge is generated and what materials used to generate it.
the charge of a lightning is positive and negative. The positive is on the top of a lightning cloud and the negative is surrounded on the bottom. As it flashes down it is a negative. However, the ground is a positive charge so as it reaches down, it turns into a positive charge. I hope this will answer you question
Negative voltage is just a voltage that instead of being positive is negative. If you think of a voltage as a large amount of water in a reservoir, with a pipe connecting it to a basin below, the voltage is the movement of the water from the reservoir to the basin. However, a negative voltage is more like a suction from the basin back up to the reservoir. Anyway, if you connect the black ( - ) lead of a 9V battery to the black lead of another 9V battery, then the connection between the two black wires is at 0V, or Ground, and one of the batteries' leads will be at +9V, and the other will be at -9V. Negative voltages are only really used in complex circuits, such as ones that contain Operational Amplifiers, and in general doesn't matter in hobby and simple electronics.

Reverse. Using a D C machine, electricity travels from the negative post to the positive post. Connecting the electrode holder to the positive post and the ground clamp to the negative post means the current flows from the work to the electrode - reverse polarity. In A C machines it doesn't matter which post the electrode holder is connected to.
The car grounding system is typically connected to the negative terminal of the car's battery, which is considered the ground or negative terminal. This means that the polarity of car grounding is negative.
Yes, the electrode holder (stinger) is positive and the ground is negative which means you would be welding DC positive.
No, not the battery. But anything that has a diode, transistor or is in any other way dependent on polarity may be fried... including your alternator.
Negative ground
The only way to tig is to have your ground clamp hooked to the positive side of the welding machine. The negative lead will go to the tig torch. If it is reversed you will find out very quickly when you strike an arc. Most metals will be welded using this Polarity (straight). Most Aluminum TIG welding is performed using A C current.
DCEN means Direct Current Electrode Negative. Hook the welding cable to the Positive connection (+) on the machine, the ground cable to the Negative connection (-) Electricity travels from Negative pole to Positive pole.
No, the ground cable gets always disconnected first and connected last, regardless of ground polarity.
You "ground" it or connect it to a negative source that is connected got the negative end of the battery
A DC voltage must have a polarity, however this polarity is always in reference to some common point and has no meaning on its own, the same with voltage. Usually this common point is the circuit ground, which may or may not be earth ground. Example: A household AA battery has a positive and a negative terminal, the positive terminal is +1.5v in relation to the negative terminal, and the negative terminal is -1.5v to the positive terminal.
If you are talking about an AC (alternating current) circuit, such as the house mains supply, "reverse polarity" usually means the "hot" and "neutral" wires from the supply have been connected to something the opposite way round to what they should be. If you are talking about a DC (direct current) circuit supplied by a battery, such as in a car, "reverse polarity" usually means the positive and negative leads from the battery have been connected to something the opposite way round to what they should be.
Cars in which the positive terminal of the battery is connected to the chassis. They require specially designed components built for positive ground cars. The usual configuration is a negative ground (the negative battery terminal connected to the car's chassis).
