Cheat Sheet
- Open Circuit Voltage Fundamentals -
Understanding open circuit voltage ____, or OCV, is essential for arc initiation; it's the no-load potential difference measured when the electrode is not touching the workpiece. This value (e.g., 70 - 100 V for SMAW) influences how easily the arc strikes and is often quizzed in electric welding quiz and arc welding voltage quiz formats (sources: AWS, Lincoln Electric).
- Voltage Under Load and Ohm's Law -
Welding voltage troubleshooting relies on Ohm's law: Vload = OCV - I × Rsystem, where Rsystem includes cable and contact resistances. Observing voltage drop under load helps pinpoint issues like faulty cables or loose connections (source: Miller Electric).
- Maintaining Ideal Arc Length -
Consistent arc length (about 1.5× electrode diameter in stick welding) keeps voltage stable; too long an arc raises voltage and produces spatter, while too short leads to sticking. A handy mnemonic is "Long arc, sparks embark; short arc, welds mark" to self-test during electric welding practice questions (source: The Fabricator).
- Polarity Effects on Voltage and Penetration -
Choosing DCEN (straight polarity) vs. DCEP (reverse polarity) alters the effective voltage at the arc and the penetration profile; DCEP typically runs at slightly lower OCV but yields deeper fusion. Always reference manufacturer specs to adjust settings accurately (source: AWS Welding Handbook).
- Best Practices for Voltage Measurement -
Accurate welding voltage troubleshooting requires placing the voltmeter leads as close to the arc as possible and measuring under real load conditions. Calibrated meters with fast response are recommended for electric welding practice questions and professional assessments (source: IEC standards).
