How does a water cooled machine gun work? The jacket is filled with water, which absorbs heat from the barrel and keeps it relatively cool. When it gets too hot, the water turns to steam and seeps out, and eventually the jacket must be refilled. The hose and condenser were added simply to prevent the steam from revealing the position of the gun.
What happened to the water-cooled machine gun?
Unfortunately for everyone’s infantrymen, the water-cooled MG lived well past the Great War. So, the infantry were stuck hauling water for the guns, well into the Korean War. But eventually, the guns were replaced with the less efficient but more manageable air-cooled guns.
What is the difference between a gas and water cooled gun?
The nozzle is insulated, electrically and thermally from the gun and radiated heat on its own. Water cooled guns act differently. With water-cooled (or gas or liquid-cooled…. they all mean the same thing), these depend on water (or liquid) to transfer heat into the power cable, contact tip and the nozzle.
How do you use a steam condenser in a water gun?
Insert the free length of the tubing into the steam condenser can ( see cans, condenser, steam) which should be about two-thirds full of water. Note .- In order to avoid injury, the tubing should be disconnected from the gun when not required for use and, when possible, during transit.
Are water cooled guns a maintenance problem?
Water cooled guns have received a bad reputation of being maintenance problems, unjustly. With operator training and the proper set up they’re more comfortable for the operator, increase arc on time and increase productivity. This article is reposted with permission from the ABIBLOG.
How do machine guns not overheat?
During this time the barrel is cooling. Cook offs in machine guns are prevented by: Cased ammunition: Among its many functions, the metallic cartridge case acts as a heat sink protecting the propellant from chamber heat. The case must first be brought up to temperature before the propellant inside can burn.
How does an air-cooled gun work?
Air-cooled MIG guns depend on thermal transfer to conduct the heat from the contact tip through the handle and into the power cable before radiating into the air. This is where the duty cycle becomes important – how much heat is generated and how fast it can be conducted and radiated?
Do water-cooled machine guns overheat?
Probably because water evaporates while firing, prolonged firing is going to use up all the water supply, then the machine gun is going to overheat from lack of coolant. Plus it puts additional burden on the logistical system, the additional water isn't gonna come from nowhere.
How does the Vickers machine gun work?
The Vickers machine gun action itself revolved around a recoil operation with gas boosting capable of a sustained rate-of-fire of 450 to 500 rounds per minute. Muzzle velocity was rated at 2,450 feet per second with an effective range out to 2,190 yards - maximum ranges out to 4,500 yards though with less accuracy.
What are some of the disadvantages of using a water-cooled gun over an air cooled gun?
Water-cooled Cons: Water cooled gun is more expensive to manufacture and needs the added expense of a cooling system. Connections and fittings on the gun are easier to damage and break – mostly because there is just more opportunity to do so. Water leaks in the welding area can be messy.
When would you use a water-cooled MIG welding gun instead of an air cooled gun?
The welding amperage will be an important factor to weigh when deciding between an air- or water-cooled system. In general, air-cooled systems are better for low amperages and water-cooled systems are better for high-amperage applications.
How many rounds can a machine gun fire in a minute?
Most machine guns are belt-fed weapons that fire from 500 to 1,000 rounds per minute and will continue to fire as long as the trigger is held back or until the supply of ammunition is exhausted.
Why are fully automatic weapons so expensive?
It can take close to a year to get approved to purchase each machine gun. Plus, because it has been illegal for civilians to buy new machine guns since 1986, only used guns are available on the market. That means it's not only a lengthy process, but an expensive one.

Why did machine guns become so important?
For the troops who wanted to continue using the machine guns to keep wave after wave of enemy troops in their own trenches and not coming into yours and sweeping you all out with shotguns, this was going to become very important, very fast.
What tanks did the Germans use to counter the Germans?
The Germans immediately counter attacked with armor, including Tiger 131. During the counter attack, British tanks of the 142nd Regiment Royal Armoured Corps and 48th Royal Tank Regiment arrived to reinforce the Foresters. German and British tank shells streaked past each other as the two sides vied for control.
What happened to the tiger in the first shot?
The first shot hit the Tiger’s barrel and ricocheted into its turret ring. The shell jammed the turret’s traverse, destroyed the radio, and wounded the driver and radio operator. The second shell disabled the gun’s elevation device when it hit the turret lifting lug.
How much did the Air Force spend on coffee cups?
In a recent scandal, the Air Force came under fire for reportedly spending over $300,000 on specialized, fragile coffee cups. That’s right — the Air Force has been buying, breaking, and replacing cups that reheat liquids in air refueling tankers mid-flight at the low, low price of $1,280 a pop.
Did water cool machine guns?
Water-cooled machine guns, as it turned out, required water to cool them. And the more you used them, the more they needed that water changed out. This may not have been terribly difficult during World War I, when movement along the front was restricted to just crossing no man’s land into the next series of trenches a hundred yards away. Unfortunately for everyone’s infantrymen, the water-cooled MG lived well past the Great War. So, the infantry were stuck hauling water for the guns, well into the Korean War.
How much water was lost in the barrel of a 450 round gun?
Captain Byrne found that when firing 450 rounds 1 1/2 pints of water were lost from the barrel casing, and slightly over 1 1/4 pints were added to the bucket of water into which the tube fed. The temperature of the water was 54 degrees before firing and 90 degrees after firing.
How much water did a B gun lose?
The amount of water lost by A gun was 3 1/2 pints, or about half the amount required to fill the jacket, while the water in the bag had increased by 2 3/4 pints, the difference being due almost entirely to a slight leakage from the front gland. B gun, after the equivalent of 850 rounds, had lost 2 pints.
What is a condenser can?
The condenser can is a standard two-gallon petrol can with a brass filler assembled over the opening of the can. The filler is designed to be inserted into the filling hole of the gun casing and is attached to the can by means of a chain and “S” hook. A clip is provided for its retention when not in use.
How much water is in a waterjacket?
Each water-jacket contained 7.5 pints of water when full. The rate of boiling depended upon the rate of fire.
What happens if the barrel casing is not filled too full?
He thought the experiment showed that if the barrel casing was not filled too full there was no chance of its bursting when the water froze, and also that the use of the muzzle attachment got over any jamming of the gun due to frozen water in the barrel casing after a very few rounds had been fired.
What type of tubing did the Vickers use?
There were various patterns of tubing used with the Vickers; the most commonly encountered being the Mk I “B” and Mk III.
When was the Maxim machine gun invented?
The Maxim machine gun also had a condenser developed for it. An early development was proposed and trialed in 1909. It was proposed by the Machine Gun Officer of the 1st Bn South Staffordshire Regiment and was discussed by the Small Arms Committee before being sent to trial.
What is the difference between air cooled and water cooled MIG guns?
Let’s begin by understanding duty cycle . We all know what it is, but just for a quick refresh: Duty cycle is a rating measurement of 10 minute increments using CO 2 gas. So, if we take a 350 amp gun as an example – that means at it’s maximum it can weld 10 minutes at 350 amps with a constant current using CO 2 gas.
What is the duty cycle reduction for water cooled guns?
Water cooled guns, on the other hand, get a duty cycle reduction of 10% for Argon base gas, and a negligible reduction for pulse welding.
Why do welders pulse?
Pulse welding is the process of pulsing your weld current several times per second instead of holding it constant. Pulsing causes the arc to act like its welding hotter than it actually is. However, the torch will react like the current is at the peak of the pulses rather than the “average” as read on the current meter of the power source. That’s because the arc is starting and stopping constantly, which takes more power. Also, pulse welding creates less smoke, considerably less, in fact, and doesn’t filter the reflected heat to the nozzle and contact tip.
Why are welding nozzles easier to break?
Connections and fittings on the gun are easier to damage and break – mostly because there is just more opportunity to do so. Water leaks in the welding area can be messy. The thermal transfer for the nozzle is a pressed ceramic and can be broken if abused, which will reduce the efficiency of the gun.
What gas is used in welding?
Now take into consideration factors that affect duty cycle. Argon base gas – which mixes Argon at 75% and CO 2 at 25% won't cool a gun like 100% CO 2. Many other gas mixes are used in welding beyondf those two mixes, such as Argon 90/10 and Argon 95/5. Pulse is yet another factor that lowers your duty cycle.
How does an air cooled torch work?
Air cooled torches depend on thermal transfer to conduct the heat from the contact tip through the handle and into the power cable before radiating into the air.
How long can a 350 amp gun weld?
So, if we take a 350 amp gun as an example – that means at it’s maximum it can weld 10 minutes at 350 amps with a constant current using CO 2 gas. Now take into consideration factors that affect duty cycle. Argon base gas – which mixes Argon at 75% and CO 2 at 25% won't cool a gun like 100% CO 2.
Air-cooled MIG Gun Cons
The longer or hotter the weld, the bigger and heavier the torch. Nozzles and tips are always hot, and depending on the delay between welds to cool, wear due to heat overexposure.
Water-cooled MIG Gun Pros
These guns are always cool. The water system will remove heat from your tips and nozzles anywhere from 30 seconds to 2 minutes after you finish welding any length of time to the point of touch. (don’t recommend welding bare handed, though!).
Water-cooled MIG Gun Cons
Water cooled gun is more expensive to manufacture and needs the added expense of a cooling system. Connections and fittings on the gun are easier to damage and break – mostly because there is just more opportunity to do so. Water leaks in the welding area can be messy.
So Which One's For You?
Water cooled guns have received a bad reputation of being maintenance problems, unjustly.
Why did water cooled machine guns go out of style?
In addition to what was already said, water cooledmachine guns went out of style with the change in tactics. Diring WW 1 and WW 2, continuous fire was the tactic used aginst waves of infantry attacking. Once the massed infantry attack became ineffective (sometime the first charge at the beginning of WWI, and the signing of the surrender on the USS Missouri in Tokyo Bay), they switched to burst fire, because there were fewer targets in the open. Burst fire is firing 3 to 6 rounds, pausing a few seconds, aim and fire another burst, observe results, repeat.
What is water cooled gun?
A water cooled gun has water pumped into a cylinder around the barrel, these usually fail from steam build up and explode, but what you have in a huge negitive, you gain a much cooler system then in air.
How many RDS can an air cooled machine gun fire?
Air cooled machine guns can only fire 2–400 rds then the bbl needs to be changed.
How many rounds can a water cooled gun fire?
Water cooled weapons have a jacket around the barrel and a water can with hose and condenser. Theoretically a machine gun that fires 550 rounds a minute can fire indefinitely as long as you have ammo and the can and condenser is working. Drawback weight and not very mobile.
Why is the M2 still used today?
So, why is the M2 still used today? Because John Moses Browning designed a perfect heavy machine gun, and there isn’t any need to mess with perfection.
What was the first semi automatic shotgun?
He designed the first successful semi-automatic shotgun, the Auto-5. It went on to become one of the most popular shotguns ever, and just recently finally ceased production.
Why does the military keep the M-2 in service?
The military keeps the M-2 in service because it’s a game changer. When it can be employed in a firefight, odds can shift in your favor… often dramatically.
