How to weld stair handrails with argon arc welding

Practice makes perfect. I have a few tips here. Tungsten wire (capillary) must be sharpened. The current should not exceed 100. Aim at the position of the welding wire you want to weld and start spot welding.

It is difficult for a novice to grasp the position at first, and it is necessary to see whether the tungsten wire is aligned.

So be sure to wear glasses and a mask. Otherwise, it will be directly irradiated by ultraviolet rays. The surface will peel off.
