What determines whether polarity of a welding machine is set up for DCEN or DCEP?
The electrode. In some cases thin materials weld better with DCEN.

What Is The Correct Polarity For MIG Welding?
DCEP for standard Mig. DCEN for Flux Core
When welding with DCEN the electrode is positive and the work is negative?
DCEN means Direct Current Electrode Negative. Hook the welding cable to the Positive connection (+) on the machine, the ground cable to the Negative connection (-) Electricity travels from Negative pole to Positive pole.
What determines weather the polarity of a welding machine is set for dcen or dcep?
DCEP supplies about two-thirds of the heat at the end of the rod, which allows more digging action, or penetration, into the base metal. It's what you want to use for thick steel. For thin steel, direct current electrode negative (DCEN) is best.
What affect does welding polarity have on where heat is directed?
In DC welding, electrode positive (DCEP) produces more heat at the workpiece, leading to deeper penetration and faster welding speeds. In contrast, electrode negative (DCEN) focuses more heat on the electrode, resulting in shallower penetration and slower welding speeds. AC welding alternates between these effects with each cycle.
Introduction about submerged arc welding?
he submerged arc welding (SAW) process can achieve high productivity and deep penetration, making it an important process for joining large diameter and/or thick-walled components such as pressure-vessels, linepipes, bridges, and ships. SAW typically uses direct current electrode positive (DCEP) polarity because of power source availability, good arc stability, and deep penetration. Greater deposition rates are possible with direct current electrode negative (DCEN) polarity, but can result in reduced penetration and arc stability. Alternating current (which shifts polarity rapidly from DCEP to DCEN) has traditionally employed a sinusoidal waveform, resulting in less time at peak current (reducing wire deposition) and more time at periods of low voltage (reducing arc stability further). However, the use of a square waveform mitigates both issues in AC SAW. Additionally, modern SAW power sources allow the welding operator to manipulate waveform variables (such as balance, offset, and frequency), providing greater control over deposition rates and penetration depths.
