How to weld stainless steel billboards

It’s about 400 yuan. I analyzed what you mean. You should buy a welding machine for welding door billboards, which is also used for welding square pipes. Just buy the 310 model.
Give me some points. I lost every penny. I often ask people questions, so I’ve given them all.

This is very nice. You first go to the place that sells the one just now. Well, buy that Guogang, which is the angle steel. Buy two of them and use this one first. Erci, let's design the height of the vertical billboard at your door, and then calculate how many pieces are needed to design its width. Well, after designing the length of the angle steel, then you can adjust the angle. , I just bought the angle steel, use this sentence to weld it, after the segment is broken, weld it with the welding rod, and just weld it together.
