What are the two types of plasma cutters?

There are two common types of plasma cutting torches. The most common torches are the high-frequency starting systems that create a spark with a high-voltage transformer, capacitors, and spark-gap assembly. High frequency torches have the advantage of not using any moving parts and therefore remain fairly dependable.

How do you start a plasma cutter?

How to Use a Plasma Cutter

1. Step 1: Choose Work Location.
2. Step 2: Plug in Unit.
3. Step 4: Turn the Air On.
4. Step 5: Attach the Ground Clamp.
5. Step 6: Turn on the Machine.
6. Step 7: Set the Current.
7. Step 8: Cut the Metal.
8. Step 9: Turn Off the Machine.

What is blowback start?

Blowback start uses a moving, spring loaded electrode that “blows back” away from the nozzle at the beginning of each cut cycle using the cutting air pressure to make the electrode move against the spring force.

How thick can plasma cutter cut?

about 1 inch
Plasma cutters are used to perform cutting and gouging operations, with the average hand-held system capable of cutting a maximum metal thickness of about 1 inch. Plasma typically requires a source for compressed air and a substantial amount of electrical power.

Do you need gas for a plasma cutter?

Gas is needed for a plasma cutter in order for it to work and create the plasma. As mentioned, the most popular gases to use are oxygen, nitrogen or argon. Nitrogen is the best choice when it comes to cutting aluminium and stainless steel and it can provide an excellent cut quality.

What is needed for a plasma cutter?

Plasma cutting requires two basic elements — air and electricity — so the next question to ask is what type of input power is available. Several 30-amp plasma cutters, such as the Spectrum® 375 X-TREME™, operate using 120- or 240-volt power.

What is a pilot arc on a plasma cutter?

Pilot arc technology allows you to cut without touching the tip to the metal. Uses non-hazardous compressed air to cut, safe and at low cost.

What is a blowback plasma torch?

A more modern approach to starting an arc is the use of “blow back” technology. This technology uses a dead short where a spring loaded electrode is firmly seated against the nozzle face and air pressure is applied to the torch. The air pressure pushes the electrode back so the air can escape from the nozzle hole.

Can a plasma cutter cut your finger off?

The way a plasma cutter works means it most likely won’t melt your finger off if you torched the plasma over it. However, it would do severe damage if your finger was underneath the metal you were cutting, due to the extreme heat that passes below the metal being cut. It has some serious heat.

What’s the difference between a HF start plasma cutter?

Re: Blowback vs HF start plasma cutter. What’s the difference? the blow back does not need contact with the metal to start an arc, it is done internally in the torch with the start air pressure moving the electrode away from the nozzle this create an arc and starts the plasma flowing.

What kind of technology does a plasma cutter use?

Plasma cutters use either high frequency (HF) start or contact start technology to initiate the pilot arc. If you plan to use a plasma cutter near telephones, computers, CNC machines or other electronic equipment, be aware that HF often interferes with electronic controls.

How does a pilot arc plasma cutter work?

Some pilot arc plasma cutting machines that use contact start have a moving electrode inside the torch. Then the main DC power is activated in the plasma torch, and just a few moments later the gas flow starts in the torch.

When did the blow back start plasma cutter come out?

– In the early 1990’s Hypertherm developed the first air plasma torch that had a strong pilot arc that could transfer to the metal regardless of surface condition, yet did not use a high frequency discharge to ionize the gas. This technology was called Blow Back start technology and was patented by Hypertherm.
