How do you optimize a plasma cutter performance?
Dry air is important for plasma cutting and maximizes cutting capacity. Keddell recommends installing an air filter and/or dryer on the machine, if it does not come equipped with one. Check, clean and replace the filter and or dryer in accordance with the manufacturer’s recommendations.
Can you get arc eye from a plasma cutter?
Plasma cutting arcs can also be very intense, because the arc current is typically anywhere from 100 to 800 Amperes. Needless to say, looking at an arc that intense can easily cause eye damage, including permanent damage leading to blindness.
How do you make a plasma cutter less slag?
Solutions: Replace worn cutting tip, especially if the orifice shows signs of wear. Decrease the speed of your cut incrementally until dross in minimized. Lower the torch height incrementally. Boost current, being careful not to exceed 95% of your nozzles AMP rating.
What pressure should I run my plasma cutter?
For the majority of the Everlast product line, air pressure required to operate the torches is anywhere between 55 to 70 psi. Low amperage cuts will require less air pressure for more stable operation, sometimes down to 45 psi or so, or the arc will be blown out.
What are the major factors for increasing cutting speed by plasma cutting?
Four factors affecting the cutting speed of the CNC plasma Model of plasma cutting machine power supply. The material of the plasma cutting workpiece is different. The size of the input voltage of the plasma cutting site. working gas and flow.
Do you need eye protection when using a plasma cutter?
Safety is of utmost priority when performing plasma cutting. You need to shield your eyes and face with proper plasma cutting glasses, goggles, and/or helmet. You also need to wear a welding gloves, welding jacket, or any clothing that is flame-resistant just like denim.
What eye protection should I use for plasma cutting?
Safety glasses with yellow lenses are recommended to block potentially damaging blue light, and a secondary shield between the operator and the cutting torch, perhaps a welding curtain or dark plastic shield, could shade the operator from the most damaging radiation.
Why should synthetic clothes never be worn when operating the plasma arc cutter?
2. Never wear synthetic clothing when using the plasma arc cutter, many synthetics are highly flammable. 3. Always wear industrial quality eye protection a #5 shaded lens is minimum for the plasma arc cutter process.
What is the difference between dross and slag?
Slag is said to be refuse produced as a result of melting non ferrous material which have a high melting point. Whereas dross is said to be related to non ferrous alloys, which have a low melting point. These are produces when molten metal comes in contact with air.
What is the current for plasma cutting?
For 3/8” cut, 40 amps works out well for most brands of plasma cutters. For ½” cut, 50 amps works out well, etc. Keep in mind this isn’t the maximum thickness of cut that a plasma cutter is capable of cutting but rather, it is a good rule to follow for decent cutting speed and quality.
How do you set a plasma cutter?
How to Use a Plasma Cutter Step 1: Choose Work Location. Step 2: Plug in Unit. Step 3: Connect the Air. Step 4: Turn the Air On. Step 5: Attach the Ground Clamp. Step 6: Turn on the Machine. Step 7: Set the Current. Step 8: Cut the Metal.
Why does my plasma cutter sputter?
One common plasma nozzle problem occurs when the orifice becomes blocked, sometimes due to molten material contacting the tip and then cooling down and hardening there, altering the plasma flow. An off-center stream will steadily wear down the orifice.
What are factors that affects the quality of cutting?
9 Factors Affecting Laser Cutting Quality ① Nozzle status. Nozzle diameter, nozzle integrity or damage, nozzle height, whether installed in place. ② Ceramic ring state. ③ Cutting head, optical path status. ④ Auxiliary gas. ⑤ Focus position. ⑥ Cutting speed. ⑦ Laser power. ⑧ Plate quality.
What are the factors influencing precise cut off?
5 factors that influence optimal plasma cuts The precision of a plasma-cut edge is getting close to perfect. Choosing the correct gas for the job. Choosing the correct nozzle. The cutting direction. The cutting speed. Consumables.
What are five factors that can affect the kerf width?
List eight items that will affect the quality of a PAC kerf. Standoff distance, orifice diameter, power setting, travel speed, gas, electrode and nozzle tip, swirling of the plasma gas, water injection.

How thick can a 50 amp plasma cutter cut?
Excellent Air Plasma Cutter: The Cut-50 Plasma Cutter can easily cut up to 0.55”(14 mm) metal under maximum output with ultimate portability weighing only 21.56 lbs.
Does a cutting torch hurt your eyes?
So yes the torch can damage the eyes, it just takes longer. Would you rather get burned by 600F molten solder or 2700f molten steel? The worse hazard for your eyes is the “blue hazard”. Watching an arc will raise the temperature in your eye to the point of pain but watching the flame will not in the same time frame.
Which type of eye protection do you use when you are performing welding works?
Welders should wear goggles or safety glasses with sideshields that comply with ANSI Z87. 1 under welding helmets and always wear goggles or other suitable eye protection when gas welding or oxygen cutting. Goggles provide better protection than safety glasses from impact, dust, and radiation hazards.
Why must cutting goggles or cutting glasses be used any time you are using a cutting torch?
UV light has the potential of causing “Welder Flash” or ‘arc eye’, with welding torches being a common source. The flash burns welders may experience are essentially like sunburn in the eye. It also states that goggles or other suitable eye protection should be worn during all gas welding and oxygen cutting operations.
