Hello Everyone,
First post on the forum, and I have a question about AC stick welding (MMA).
I always understood that after striking an arc, you need to keep the end of the electrode about the same distance from the work as the electrode diameter itself. So 3mm from the work for a 3mm stick.
I see a lot of fabricators balancing the stick on their other hand to achieve the correct arc length as they move along the work piece.
Then I saw the video below. The guy just rests the electrode on the work piece and drags it along. Skip to 10:17 for the action.
Is it the type of electrode he's using (7024), the diameter (3.2), the higher current (170A) or something else? He's also about 45 degrees from vertical with the electrode.
Would be much easier to just drag the rod rather than try and keep a constant arc length as you weld.
Thanks.
