An introduction to the air cored coil
Using a 5 millimetre diameter drill bit wrap the wire around it until enough turns have been applied. Using ''long nosed'' pliers bend the ends of the coil to get them into a radial position. Small reductions in the inductance obtained can be achieved by pulling the turns apart slightly.

Shielded metal arc welding - Wikipedia
Shielded metal arc welding (SMAW), also known as manual metal arc welding (MMA or MMAW), flux shielded arc welding or informally as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld. An electric current, in the form of either alternating current or direct current from a welding power supply, is used to form an electric arc
Shielded Metal Arc Welding - an overview | ScienceDirect …
Shielded metal arc welding (SMAW) is the simplest, least expensive, and mostly widely used arc welding process (Figure 2).It is often referred to as ‘stick welding’ or manual metal arc welding. This process produces coalescence of metals by heating them with an

CARBON- I could have maybe dealt with the first 2 cons for the duration of the roll, but this darn sf deposited so much carbon inside my machine, it completely gummed it up within a short period. Any money I thought I was saving purchasing this brand, I wasted by not finishing the roll of wire and by all the time I had to spend cleaning a crazy amount of carbon out of my machine.
22 possible causes of weld metal porosity - The …
However, depending on the welding code or standard, porosity might be cause for a weld reject. Luckily, porosity is a defect that has an approximate 90 percent prevention rate. With a few tips for identifying possible causes of the porosity, a welder quickly can turn reject parts into weldments that are acceptable under most welding codes.
