Why is a point of penetration of 2 square steel welding
Electrode selection 2, 0J422, welding current about 80, if conditions permit, you can use carbon dioxide welding, welding process is very good grasp.
Now the steel mostly under poor material, 2 - 0 1 - 8 square the actual thickness is good, which is on the one hand, choose another current must be small.
With 2.5 of the electrode try, I solder 1 will do, hand gestures as soon as possible, it is not so easy to point out the hole, if the conditions can choose carbon dioxide protection welding, but the cost of welding should be high
