Lecture Notes: Welding Techniques with AHP AlphaTig 200X

Introduction

  • Presenter: Bob Moffitt, Weld.com
  • Equipment: AHP AlphaTig 200X
  • Focus: Stick welding with various electrode rods

Objectives

  • Test the AHP AlphaTig 200X machine capability in both AC and DC welding.
  • Experiment with different rod sizes and polarities.

Materials Used

  • Various electrodes:
    • 532nd 7018
    • 1/8 inch 7024
    • 3/32nd 6010
    • 1/8 inch 6010
    • 532nd 6010
    • 3/32nd 7018
    • 6013
  • Amperage Settings: Started around 160 amps, various adjustments made

Experimentation

  • Challenge to avoid sticking electrodes.
  • Tested various rods for performance, ease, and results.

Machine Features

  • Polarity Adjustment: Switch leads for DC, AC settings.
  • Frequency Adjustment: Active in stick welding; tested at 60 Hz and 170 Hz.

Welding Techniques

  • 7024 Rod on AC: Set at 120 amps. Goal is straight bead lines.
  • 6010 Rod on DC: Aggressive and different from 7024, requires careful handling.
  • 6011 Rod: Compared to 6010, runs on both AC and DC.
  • 7018 Rod: Runs on both AC and DCEP (reverse polarity).
  • 6013 Rod: Demonstrated as versatile across all polarities.

Key Observations

  • Slag Peel: Greater peel seen with certain rods and settings
  • Arc Stability: Issues noted with 6010 rod, adjustments made for better performance
  • Iron Powder Rods: Forgiving but require specific handling

Questions Posed

  • Why use alternating current with rods like 7024 or 7018?
  • Differences and uses of rod types (e.g., 6010 vs 6011)

Practical Tips

  • Electrode Efficiency: Utilize rods efficiently, learn restarts.
  • Welding Positions: Know when to run rods uphill or downhill.
  • Equipment Familiarity: Importance of knowing adjustments and settings on machines.

Conclusion

  • The AHP AlphaTig 200X has impressive capabilities, especially in adjusting stick welding AC frequency.
  • Encouraged viewers to comment on the advantages of AC in stick welding.

Note to Students: Understanding the different rod types, their qualities, and how they interact with different machine settings is crucial to improving welding technique and efficiency. Practice different positions and familiarize yourself with the equipment to develop better welding skills. Subscribe for more educational content.
