What are the dangers of arc flash?

An arc flash occurs when electrical current jump from one conductor to another. An arc flash is like a spark on steroids, as it is a high energy, short duration current flow through the air.

Because of the high energy, very high temperatures are created. The air in the gap is heated and expands; the conductors at each end of the flash are heated and vaporized in less than one cycle. The resulting gas/vapor expansion is explosive and extremely hot.

The dangers to people include

  • explosive pressures that can throw people across a room
  • essentially instantaneous ignition of combustible clothing, including silks and cottons
  • severe burns, including 4th degree burns
  • death

Approximately 5% of arc flash victims die, and another 20% are permanently disabled. The remaining survivors often have not fully recovered after decades of continuing treatment, some requiring multiple surgeries each year.

In addition, the arc blast resulting from the arc flash can severely damage equipment, to the extent that equipment enclosures are shredded and become dangerous shrapnel.

Burns can effect unprotected people many yards away from the flash point, as can the blast and shrapnel.

Is a welder a physical work or is it mental?

Reverse polarity means that the current is going the opposite way, from the grounding clamp, through the metal, and up through the electrode.

What is stickwelding?

Stick welding is a type of welding that uses an electrical current to produce an intensely hot plasma arc that melts metal together while adding filler metal, which is what the "stick" electrode is made of. The electrode (or stick) is usually about a foot in length and is covered in flux to prevent atmospheric contamination. It is held by an electrified clamp that the welder runs across the joint to weld.

How do you use your portable welder to weld aluminum?

the only way you can weld aluminum is with AC current and high freak setting on the welder , if your welder does not have theses setting then it will not weld aluminum.

Good answer! AC is a must! The only other way is if you have an oxy/ace setup (very low psi) or alot of mapp gas, but you have to spread a flux paste on the material (looks like drywall mud) EXTREMELY MESSY!

How do you change a 4-wire 240V plug for a dryer to a 3-wire 240V plug for a welder and which wires do you use?

The existing 4 wires meaning Red, Black, White, Bare? Red and black are "hot" (using 120V from each phase of your service entrance), white is neutral, and bare is ground.
