A.5 PRIMAR Y PULSE W A VEFORM COMPONENTS The following paragraphs describe how peak current, peak time, frequency, and background current effect weld droplet transfer. A.5.1 PEAK CURRENT AND PEAK TIME A combination of peak current and peak time, Figure A-6, applies a force to detach the weld droplet from the electrode and propel it across the arc. [...]

A.5.2 FREQUENCY Frequency, Figure A-7, is the number of pulses per second or, in theory, the number of weld droplets per second. Since increasing the frequency generates more pulses in a given time period, higher frequencies generate higher average current levels. FIGURE A-7. FREQUENCY.

Our Experiment: We found multiple droplet detachment with an arc length that was too long at these waveform settings. To attain the proper droplet detachment, we reduced the peak current value to 250 amps and found improved weld droplet transfer. But reducing the peak current also caused the arc to be shorter. Then we needed to lengthen the arc. We[...]

B.5.1 PEAK CURRENT The peak current control acts similar to an “arc pinch” control. Peak current serves to establish the arc length and promote good fusion. Higher peak current levels will caus[...]

B.5.3 T AILOUT The tailout provides additional heat without the molten droplet becoming too large. Increase tailout as needed to add heat to the arc without increasing arc length. (This will allow for faster travel speeds and improved wetting). As tailout is increased, the peal and/or background current is usually reduced. Appendix B B-13 STT W A V[...]
