Practical Testing

Test 1: 60 13 Electrode at 65 and 75 amps on 120V

For the first practical test, we used a 60 13 electrode, initially setting the DEKOPRO Welder to 65 amps on a 120V outlet. The welder ran smoothly at this setting, laying down consistent beads. However, we felt the need for a bit more heat for better penetration. Consequently, we increased the amperage to 75 amps. This adjustment resulted in a noticeable improvement in the weld quality. The beads were more uniform, and the increased heat facilitated better fusion with the base material.

  • Observations: Performance, Heat Settings, and Weld Quality
    Throughout this test, the DEKOPRO Welder demonstrated its capability to adapt to different heat settings effectively. The digital readout was particularly helpful in making precise adjustments. The weld quality at both 65 and 75 amps was quite satisfactory, especially considering the machine’s compact size and price point. The welds were consistent, and the arc stability was commendable.

Test 2: 1/8 inch 60 13 Electrode at 105 amps on 110V

In the second test, we used a 1/8 inch 60 13 electrode, pushing the welder to 105 amps while still connected to a 110V outlet. The welder managed to run the electrode, but it seemed to struggle slightly, indicating that we were approaching its limits on a 110V supply. The bead appeared a bit colder than expected for 105 amps, suggesting that the actual output might have been lower.

  • Comparison: Performance on 110V vs. 240V
    To further explore the welder’s capabilities, we switched the power supply to a 240V outlet, maintaining the same settings. The difference in performance was stark. On 240V, the welder ran the 1/8 inch electrode much more effectively, producing a hotter and more penetrating weld. This test clearly demonstrated the machine’s enhanced capability when operated on a higher voltage supply.
  • Limitations: Maximum Effective Output on 110V
    From these tests, it’s evident that while the DEKOPRO Welder performs adequately on a 110V supply, its output is somewhat limited. For lighter tasks and thinner materials, it’s quite sufficient. However, for more demanding tasks, especially those requiring higher amperage, switching to a 240V supply unlocks the full potential of the welder. This dual voltage flexibility is a significant advantage, but it’s important to recognize the performance boundaries when using the lower voltage option.
