The electrode identification number tells you that the electrode (E) has 70,000 pounds of tensile strength (70) and is suitable for all welding positions (1). From the chart above, the coating is low hydrogen potassium and iron powder with AC, DC, or DC- welding currents. What are the...
It's relatively simple to set the controls on a MIG welder: Most welders have a settings chart to help inexperienced operators with the initial settings. They can later adjust the settings for amperage (wire speed) and voltage (heat) to improve the weld. It's easier to start a MIG weld:...
Spray. In the spray transfer mode, molten droplets of material—usually smaller than the diameter of the electrode—spray across the workpiece. This mode uses a variety of mixtures from 80% to 98% argon with 2% to 20% CO2 and requires higher voltage or amperage, faster wire feed rates, th...
QUESTIONHi, Great website keep up the good work. just a question. do you know of somewhere i can get a chart that shows the different frequency and pulse combinations for different jobs(eg electrode size and metal size). thanks ANSWER… If you find one please let me know. The only reco...

Miller provides two tools to simplify setting proper voltage and amperage: A convenient reference chart, located on the inside of the door housing the wire feed system Miller Auto-Set™ technology is found on the Millermatic models. Simply select the wire diameter you're using (a blue light...
The E indicates Electrode because remember, some welding rods are not electrodes. Tig welding rods for instance are usually not used as an electrode but are usually labeled with a ER for electrode or rod because they could be used for either…I don’t see it, but that’s the idea. ...
or intersections. Workpieces are held together at the predetermined points under force by one or more electrodes. The contacting points are heated by a pulse of high amperage welding current generated by contact with an electrode. The resistance to the flow of welding current through the workpieces...
