Re: Everlast Welders
A 6010 has a cellulose flux...Think of it as a piece of metal rod being surrounded by newspaper. That's pretty much a 6010. The burning of the cellulose creates a gas cloud around the weld until it cools, which it does very rapidly because the remaining slag is very little and very tightly held to the weld.
I am not a metallugist, but I know that some rods have alloys and compounds in the metal and the flux such as silicon, lime, and iron powder that help stabilize the arc and wet in the puddle. The 6010 does not. The 6011, which is very similar to the 6010 sharing a similar cellulose flux does have some stabilizers. The problem with these "additives" is that they sacrifice penetration. The 6010 is generally used for root pass welds when welding pressure vessels and any type "code" work. It offers a stiff forceful arc, but the arc is generally held very close. As the arc gets closer, the volts begin to drop. In welding, it really isn't just amps that does the welding, its both volts and amps that you are concerned with, or rather your total watts of power. So even though the amps stay the same, the voltage drops to almost nothing on typical transformer machines and on many inverters. The 6010 setting boosts the "watts" of power synergically when the arc is held close to keep the rod burning even and stable.
