Sweating

Hi, I hope I’m right here in the forum, I didn’t find anything more suitable. So I have an old barkas and I’m just welding the body. The welding device is a “migboy 200” from messer griesheim so a protective gas gets. Before I didn’t have a very big sweating knowledge, but I can manage now. However, I have problems with the correct setting of the device from time to time. Meistst does this with the setting so that I get super beautiful welding points (to be sure, But then it happens again and again that on my exercise sheets the biggest holes are simply fried. I know, this is above all a matter of exercise and also a matter of feeling. That’s the only way I have such problems to get a good feeling. Since I want to spare myself a relatively expensive welding course, I hope to get advice here (for the sake of being able to still attend a course) The problem is that I do not want to miss out on any other plates, but I hope to get advice here. hrmal quite well knows what the buttons mean (sounds funny now, but when it was set up there were no problems) and in the internet I could not find a guide in my search. So I have a large central rotary knob (continuously) which is responsible for the wire feed (and probably also regulates the voltage). Then a smaller rotary switch with 12 steps, which probably adjusts the current strength (?). Then there are two connections into which you can insert the mass of the plugs kan n (once 220 and 380 volts ?). Furthermore, there is a small stepless rotary switch which, according to the symbol, should have something to do with the wire length outside the burner. I hope for quick and nice help. Thanks already. I could come to a picture of the switchboard, but since I only have mobile internet and the workshop is a bit away. That’s why everything is mostly small.
