From inside the machine follow the wires coming from the front panel control connection. Look closely for you will most likely find either a broken, disconnected or loose wire. The wires from the front panel connection run 1st to a small PCB( 1"x2" roughly) mounted vertically at the bottom front right of the machine frame, you may want to remove that pcb to get a closer look the connections. Wires then leave that PCB and run to a snap in connector on the front left side of the front bottom PCB, check the wiring that terminates in that snap in connector.

Turn the power off on the machine and check the continuity of the trigger wires with a continuity tester to make sure they aren't shorting together.

Could be as simple as having the ground cable connection placed into the wrong port on the front of the machine. Foot peddle/machine selection switch in peddle mode instead of machine mode? Internally it could be high frequency spark leakage or failed HF circuitry. These are the most common causes of spark failure. Oh and be sure you have good consumables and they are installed correctly. Air pressure leaving the torch head should be around 70 psi.

Have you watched to see if the pressure light comes on right before shutdown? If so you may need to add a tank right next to the torch base to address the pressure drop assuming your air source is able to deliver adequate volume to the cutter continuously and you currently have more than 25 feet of hose between cutter and compressor. It might not hurt to check the internal filter as well.

Thermal Dynamics cutmaster 81. when turned on it cycles blowing air but no arc. two green lights are flashing. pulling the trigger doesn't do anything, air keeps cycling


Hi; Check the following troubleshoot and see if you can ID the problem:
Problem: Gas flows continuously when power is turned on, AC indicator flashes 1. Torch switch is activated (closed) before user turns power on. a. Release torch switch. 2. Faulty torch switch a. Check torch switch for continuity. Replace if necessary.
Problem: Gas flows continuously; Torch will not pilot when torch switch is activated; AC indicator ON 1. System is in SET mode a. Change to RUN / Rapid Auto Restart / SET switch to RUN (up).
Mostly of the problems found is that customer has the switch line on to SET instead of RUN.
Hope this help. Have a good afternoon.

It has become my experience that the trouble is in the torch head, especially after the torch head has gotten hot during use. Replacing it may solve your problem.

Hobart 250 a keeps cutting off the flame


If you have a bad air supply then the moisture in the air will cause the torch to cut off and the cut quality depends also on air supply,speed,metal thickness and condition of your consumables,meaning your electrode and other related parts in the torch tip.Hope this helps

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.
