Wire is measured in gauge. There are several different gauge standards so it is common to use the decimal measurement instead of gauge now. Nichrome wire and other non-ferrous metals use the AWG gauge standard, American Wire Gauge, and this is the standard I use on my Web site but I also list the decimal. You can use any wire size you want to. Foam can be and is cut with wire sizes from 40 gauge (.003" dia.) all the way up to 11 gauge (.091" dia.). The temperature of a straight wire in room temperature calm air can be calculated. A given temperature will result in a specific current flowing through a specific diameter wire. It doesn't matter how long the wire is, a given current flowing.
A 12 volt power supply will power up to 24" of 26 gauge wire. This would include nearly all table top foam cutters which is the most common type of foam cutter, and would include small bow cutters. This is why 26 gauge is the most common. 24 gauge to 30 gauge has also been used for table top models.
Most foam cutters take a moderate current and low voltage. For example, with a 12V transformer, you put in 120V and you get out 12V. That is a ratio of 120/12 or 10:1. The current is increased 10 fold and the voltage is reduced 10 fold.
A short piece of 40 gauge wire has been used with a 9 volt battery to cut very thin (.020") and narrow strips of foam for air surfing walk-along gliders. Two D cell batteries can power a 4" piece of 32 gauge nichrome wire in a small hobby hand held foam cutter. A 12 volt power supply will power up to 24" of 26 gauge wire.
From the temperature chart on the Jacobs site... for the same temperature (i.e. 800*F) 30AWG needs only ~1.5 amps whereas 26AWG will require ~2.6 amps. It probably comes down to finding a suitable power supply. .WARHAWK. Thanks, My power source is rated at 3.6 A, will it melt the wire ?
As it turns out, the voltage requirement for 18" of nichrome wire at 800F is 10.4 volts so instead of a 24 volt output transformer, a 12 volt output, 50 Watt transformer can be used. The current capability is 50 / 12 = 4.1 amps, well above the 2.6 amps required.
Other material: Actual nicrhome wire, not guitar wire, and here is why. For a hot wire cutter, you would need to fashion a holder that meets your requirements, as well as some nichrome wire.
There are many different types of batteries, and you can test all of them to see if they're charged or not. Alkaline batteries bounce when they're going bad, so drop one on a hard surface to see whether or not it bounces.

Battery Chargers or Power Adaptors are not necessarily the same thing. A power adaptor just transforms your mains voltage (240V or 110V depending on your country) to a suitable voltage for. So far I have talked about Voltage but the current power in terms Amp or Milliamps needs to be considered along with Voltage. Its all well and good having a 12V adaptor or power supply. Please note that making a purchase from following one of the links above may provide a small commission which helps in the running of this web site. Next thing to consider is the plug and polarity of that plug that inserts into the laser or device. Most these days are of the type pictured below,.
Many laser levels are sold with rechargeable batteries together with chargers or power adaptors. Sometimes, users lose or misplace their chargers and might consider plugging in a charger for another device. There are risks involved in doing this as the image below highlights.
The laser uses a rechargeable 3.7-volt 2500MAH lithium-ion battery. Since it's rechargeable, you don't have to worry about constantly replacing the batteries. You can just charge up the laser and leave it in the kit.
Battery Chargers or Power Adaptors are not necessarily the same thing. A power adaptor just transforms your mains voltage (240V or 110V depending on your country) to a suitable voltage for the device, for example, 6V or 12V etc.
This is because there is no control over the flow of power into the battery. It could even cause a fire with Ni-MH or Li-ion batteries. So if in doubt do not plug it in, contact the supplier of the laser level for advice.
Even if it does fit into your laser it may have the wrong polarity. DC has a positive and negative terminal the same as your batteries. Some power adaptors and chargers have the positive terminal as the inner part of the plug and the negative as the outer. Some may be the opposite with the negative being the inner and positive being the outer.
Therefore, even if you have the correct voltage and current it may still not plug into your device. Even if it does fit into your laser it may have the wrong polarity. DC has a positive and negative terminal the same as your batteries.
