What type of welding machine will you be using, Transformer Rectifier - Single/Three Phase primary input, Motor Generator, Limited Wattage/overlapping amperage ranges Engine Generator - Single/Three phase weld output, engine generators/alternator w/inverter/chopper outputs, inverter/electronic? Some or all the machines may or may not weld 6010 very well or as well as expected. Inverters have or have had a propensity for arc outages when whip & pause technique is used with some 6010s. There is a reason an electrode manufacturer may have two or more offerings for one classification.
Have your distributor help you with sample packs of electrodes to see which one in your humble opinion provides the arc you like. 6010s could produce a globular or spray transfer dependent on their flux formula.

I have been using Lincoln 5P+ for 9 years exclusively and have used them on an old Lincoln Ranger 8, old SA250, a new Vantage 300 and my shop machine is a Lincoln 225 TIG machine I use more for stick than TIG. I have never failed a weld test or xray with either of these machines or the 5P+ E6010's. Personally, nobody else makes a 6010 rod that compares to Lincolns products. Just my .02 cents.
