Hi:

Your plasma has a start arc pilot inside the machine, this one must be faulty, check your owner's manual and request the part to your nearest welding store. It is easy to replace.

No Arc on a Cut 40 Plasma cutter


Check your consumbales to be sure they are tight in the torch head. Check your ground be sure it's good and connected to the pc you are cutting. Make sure you are running air at 65 to 70 psi as it exits the torch. Email me if you have any other questions.

Pulsating Arc


Sounds like one or two of the power diodes are defective (open), producing a half wave pulse instead of full wave, giving it a dotting effect.

Plasma cutters Question


There are a few things about plasma cutting safety that are different from general welding safety tips This short list of plasma cutter safety tips is geared toward light duty plasma cutting using compressed air not large industrial units that use gas mixtures and water cutting tables. Electric Shock Can Kill - Operating a plasma cutter completes an electric circuit between the torch and the workpiece. The workpiece and anything touching the workpiece are part of the electrical circuit. - Never touch the torch body, workpiece or the water in a water table when the plasma system is operating. Voltages & Currents - Plasma cutter output voltages are much greater than welding voltages, usually 100-200 volts. Precautionary Measures - Do not pick up the workpiece, including the waste cutoff, while you cut. Leave the workpiece in place on the workbench with the work cable attached during the cutting process. - During plasma cutting operations do not move the work clamp. Wear insulated gloves and boots, and keep your body and clothing dry. - Do not stand, sit or lie on or otherwise touch any wet surface when using the plasma cutter system. - Insulate yourself from work and ground using dry insulating mats or covers big enough to prevent any physical contact with the work or ground. If you must work in or near a damp area, use extreme caution. Work Cable - Ensure metal-to-metal contact between work cable and workpiece or work table. - Work cable clamp should make contact with clean metal free of rust, dirt, painted surfaces, etc. - Do not attach work cable to the piece that will fall away when the cut is complete Plasma cutter Arc Rays Plasma cutter arc rays produce intense visible and invisible (ultraviolet and infrared) rays that can burn eyes and skin. Protective Clothing - Guantlet gloves, safety shoes and hat. - Flame-retardant clothing to cover all exposed areas. - Cuffless trousers to prevent entry of sparks and slag. - Remove combustibles, such as a butane lighter or matches, from your pockets before cutting. Noise Levels of Plasma Arc Cutting - Plasma arc cutting systems can generate noise levels in excess of 120 dB during high-amperage cutting operations. - Ear protection should be used when operating or working near plasma arc cutting operations. Toxic Fumes & Gases Plasma arc cutting can produce toxic fumes and gases that deplete oxygen and cause serious injury. - Keep the cutting area well ventilated or use an approved air-supplied respirator. - Do not cut in locations near degreasing, cleaning or spraying operations. The vapors from certain chlorinated solvents decompose to form phosgene gas when exposed to ultraviolet radiation. Pacemakers & Hearing Aids - Pacemaker and hearing aid operation can be affected by magnetic fields from high currents. Pacemaker and hearing aid wearers should consult a doctor before going near any plasma arc cutting and gouging operations Overall Plasma Safety - The plasma arc cutting process can be very safe. - By paying attention to safety standards and correctly setting up and operating the system, plasma arc cutting poses no more a threat than most welding processes.

Plasma cutters problem


Depending upon the design of the torch (e.g., orifice diameter), electrode design, gas type and velocities, and the current levels, several variations of the plasma process are achievable, including: * Plasma Arc Welding (PAW) * Plasma Arc Cutting (PAC) * Plasma Arc Gouging * Plasma Arc Surfacing * Plasma Arc Spraying

Plasma cutters support


Plasma Arc cutting is an excellent choice for most cutting applications but it is particularly well suited for applications where speed and excellent cut quality are important. Because of the intense heat of the plasma arc – around 40,000° F compared to 5,700° F, with gases used with Oxy-Fuel torches – the cut is clean with little or no dross.
