Ensure you have a good ground connection.

try setting your machine to a lower setting for sheet metal.

approx. 25 amps, and about 2 to 2.5 bar

finally movement is everything, smooth and steady.

settings vary from machine to machine, good luck

I'm needing to make a series of kerf cuts on a 12' wide plywood piece in order to bend it in a 15" arc. My problem is the kerf cut is deeper in the back of the board than the front.

It is important for even cuts that the board is fixtured properly. I would secure the plywood to a second board that is flat stiff and strong. A table top that is not warped may work OK. This will prevent the plywood from bending from the weight of the saw.

Use a scrap piece of material at the exact thickness of the plywood to allow the saw to cut through the width of the plywood .
You need to cut past the back edge to ensure the kerf depth is consistent.

If you cannot hold the saw flat and steady you may also need a lead in piece so the saw is flat and square before beginning the cut into the 12 inch wide plywood.

I would use a fence along the side of the saw as a guide relocating after each cut.

Minimizing Paper Jamming in any printer

When using any laser printer, monochrome or color machine, be sure to fan the paper before inserting into the paper cassette tray. The technique is simple. Holding a stack of paper in your hands, each hand on the short edge, flex the paper to create an arc in the stack. Then pinch down on the ends of the paper and straighten the arc out. You'll produce a bulge in the middle of the stack which creates an air space between every sheet in the stack. Now the paper will not cling and paper jams will not occur.
The 2nd tip is to note which "direction" the paper is cut because feeding the paper in one side first may provide better traction than if you were to feed the other end in first. Paper has a grain and its lays down in one or the other direction.

Samsung electric dryer keeps burning up thermal cut-off thermostat

I am not familiar with the model.

That the thermostat keeps failing, due presumably to overheated/burned contacts does indicate the element is drawing too much current. I can think of no other reason to explain your experience except possibly there is excessive arcing at the contacts as they open and close. The addition of a suppressor capacitor might help but the big question to be answered is why is there too much current or excessive arcing...

I can only suggest you thoroughly examine the heating element looking for breaks and accidental short circuits between the coils of the element or connecting wires.

Hi, hold the unit upside down and loosen the two screws. Now, slide the plate to the right and make sure that it is straight with the cutting teeth. Tighten lightly the left screw, then check for straight, then tighten lightly the right screw. Again check for straight. Once you have the straight actually straight, tighten the screws more firmly. Test the unit. If it does not cut right. Loosen the screws slowly and move the plate 1 mm to the left. This is a matter of small movements to get it just right. You may have to move the plate a few times. Always, the screws need to be loosened and tightened slightly so as to keep the plate straight.

Spectrum 2050 plasma cutter . Cutter blows air and stops when trigger is pulled no pilot arc or any cutting when trig is released air flows again and stop after 10 sec new tips was working the day...

Check compressed air pressure is in limits otherwise unit will cut out. Try adjusting the pressure up. also make sure the supply pressure is correct as it may not be your plasma cutter at fault.

Only cuts for 3 seconds, device still on

Possibly an internal short in the torch tip... the expendable components failing in the tip will cause the sensors in the machine to register a "no cut" or "free air arc" state and kill the power to the tip to prevent damage to the unit. Replace the tip components and double check the grounds connections.

Echo CS370. Just got back from shop. It cuts in an arc not straight down The Echo Logo on the bar is upside down. It was sharpened at the shop but spits out dust not chips.>

it's possible that the chain was installed backward. the cutting in an arc is caused by 2 things. A dull chain and the guide bar being worn into a radius where the chain rides. the guide bar surface where the chain rides needs to be flat and square to the sides. since the logo is upside down this shows that the bar has been flipped to use the other edge of it. the teeth on the chain on the bottom of the bar need to be facing the operator in order to cut

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.
