The peak current can be as high as 1,000 amperes, which is more than enough to heat up the metal.
“This is the first time we’ve seen a machine that can do this, and it’s a big step forward for the industry,” said Dr. Michael J. O’Connor, a professor of electrical and computer engineering at the University of Illinois at Urbana-Champaign, who was not involved in the research.

What is a hot start and when should it be used?
A “hot start” is a method for starting up a new or resurfaced pool using a lot of acid. It’s aggressive and causes it to become brittle because it etches calcium off the surface.
The acid used in the hot start process is called hydrochloric acid, or HCl, and it is the same acid that is used to kill bacteria in swimming pools. The acid dissolves the calcium from the pool’s surface and hardens it, making it more resistant to corrosion.
In fact, the acid is so strong that it can be used as an abrasive, which is why hot starts are often used on concrete and steel surfaces. Check the list below
- Hot starts can also be applied to wood
- Concrete
- Brick
- Stone
- Tile
- Metal
- Glass
- Plastic
- As well as to metals
- Aluminum
- Copper
- Iron
- Zinc
- Lead
- Mercury
- Cadmium
- Arsenic
- Nickel
- Cobalt
- Manganese
- Molybdenum
- Bismuth
such as rubber tires and tires with rubber treads

Why would you use hot start on an SMAW welding power supply?
SMAW power sources can be set so that strikes don’t result in a big knot at the beginning of the weld. The hot start function increases the welding current for an adjusted time at the start of the weld, which reduces the risk of poor fusion when the arcs is struck. “Hot start ” is also used to increase the strength of welds.
When hot start is used, a small amount of heat is applied to the material, causing it to heat up. The heat causes the metal to expand, increasing its strength. Hot start can also be used in conjunction with other welding techniques, such as arc welding.
What is adaptive hot start in welding?
Automatically increases the output amperage at the start of a stick weld, should the start require it. AHT is a feature that automatically starts the welding process when the power is turned on. It is designed to reduce the time it takes to start a weld and to prevent the weld from becoming stuck. This feature is not available in all applications.
What is the advantage of a hot start welding?
The function of the “hot start” allows the metals to be fused together easier at the beginning of the weld in order for them to be more easily welded together. “Hot start ” is a function that can be used to determine if the metal is hot enough to start the welding process. This function is called the hot start temperature.
It is measured in degrees Celsius (°C) and is expressed as a number between 0 and 100. For example, if a metal has a temperature of 100 °C (212 °F), then it is considered hot. If the temperature is lower than this, then the material is too cold to begin the process of welding.
The temperature can also be set to a value that is higher than 100, in which case it will be considered too hot to weld. In this case, you will need to adjust the amount of metal that you are welding to ensure that the heat is evenly distributed throughout the entire weld area.
How does a hot start work?
The hot start adds more air to the fuel and air mix. If the engine is running hot, the air/fuel mixture will be hotter than it would be if it were running cool. As a result, more fuel is burned, and more heat is generated.
The hotter the mixture is at the start of a hot engine, so is the amount of fuel that needs to be burned in order to maintain the desired operating temperature.
In the case of an engine that has been running for a long period of time, this can result in a significant increase in fuel consumption, especially if the temperature is high enough to cause overheating of the cylinder walls, which can lead to premature detonation. When this happens, it can cause a spark to ignite, causing a fire.
It is important to note that this is not the same thing as a “fire” or “explosion”.
What causes a hot start?
The condition is known as a hot fire. In the case of an engine failure, the engine will not be able to start, and the pilot will be unable to control the aircraft. In the event of a fire, it is important that the fire is contained and extinguished as quickly as possible to prevent the loss of life and property.
