All welcome. We continue to dismantle our welding diary, today I want to discuss such an important topic for beginners in welding and how to put the welding current? Because it is one of the most important terms of getting the normal penetration of the parts. I'll start with the bad news. Many of our domestic welding inverter outputs a welding current is less than that stated in the instructions, unfortunately it is. So putting krutilki current 100 amperes, in fact there will be less. It follows a simple conclusion - no need to navigate at exhibiting current table and the regulator (krutilki!) Of your device.
So what to do? How to put the welding current, especially when the experience is not enough? We will pursue this method scientific! Suppose that you need to weld two pieces of iron, and you have a certain diameter electrodes. The first thing we need training unnecessary piece of iron of the same thickness as the weldability. First expose on the apparatus deliberately small current - albeit conditionally take 30 - 40 Amps, and try to cook on a training piece of iron. The electrode stick and poorly brews suture fails.
Adding a time of 10 amps and trying to believe the seams until the current is too strong and will not begin burned naturally doing this all on the training piece of iron. Do not forget to watch your desired polarity of the electrodes, it is listed on the pack.
When you weld on seams on the training piece of iron, do not cook them next to each other - on the contrary, each next seam to do away from the previous one, because the metal next to the seam is strongly heated and can get inadequate conclusion .
Once started strong burned at high current, easily take away as 10 amps, and you are now quickly pick up just the right current and the electrode is not limes and was not burned strong. Here and I have to start getting a normal joint.
Guys, just so the method of self-selection, you can set the optimum welding current for your purposes. I would like to cite the example of cool videos from YouTube channel MastakSvarka, where a person puts the welding current from the table and out of this comes out.
