Friends, you are on the channel for beginners garage-country self-taught in welding and locksmiths.
Here, in articles and videos, we give simple practical tips for beginners to shorten the path by trial and error to normal results several times.
A hot topic for a beginner is welding of thin metal with a pull-off. This is, for example, welding a profile pipe, because it is the most massive material for home and summer cottages.
The wall of such pipes is rather thin, we usually buy pipes with a thickness of 1.5-2 mm. Based on this, it is necessary to weld such pipes mainly with frequent separation, point by point, otherwise, especially for a beginner, there will be a burn-through on the burn-through.
With this welding technique, one of the important components to facilitate the work will be the correct position of the electrode in the welding holder. What are these provisions? The most common ones are we clamp the electrode either at 90 degrees, or at 45.
Is there any difference what the position of the electrode in the holder is? Yes there is, look.
Pull-off welding of thin metals is precision and speed so as not to overexpose the electrode in place and not get burned through. Therefore, we need to do this moment of separation and re-ignition as conveniently as possible.
Therefore, we clamp the electrode at 90 degrees. This position of our brush in relation to the electrode will allow you to easily and quickly start and interrupt the weld spot. This will be especially noticeable when the electrode is new, I mean the maximum length, and not the time after manufacture!
But as soon as about half the length of the electrode rod has burned out, then this difference in the control of the pull-off weld is evened out. Now there is no particular difference in convenience, even if you clamp it under 90 or even under 45.
So for a beginner, any little thing will be useful. Today's article with such a simple recommendation is just one of those tips. For an adequate comparison, just try to boil with a separation with a new electrode and under 90 and 45 degrees. in the holder.
