When argon welding machine welding aluminum, how to set?
Mainly depends on your welding machine, there is no AC welding function. If necessary, with the flow file on the line, as well as the time to adjust the duty cycle when welding
Welding aluminum must be exchanged unless the edges are polished by direct current welding
Welding aluminum to use square wave communication, set more, do not know what kind of argon arc welding machine. The width of the cleaning and the AC frequency should be adjusted first. When welding, the tungsten rod should be pure tungsten and will be welded into a ball at the front of the tungsten rod. This will have a good effect on cleaning the weld surface and make the weld bright.Welding stainless steel is much simpler, the use of direct current output, direct adjustment of current size can be, tungsten rod generally use thorium, tungsten or cerium tungsten, welding in the tungsten rod grinding point, so that it will not arc.AC welding is not adjustable pulse, AC and pulse frequency is different, the pulse is base current and peak current to each other, there will be fish welding welding scar mouth squamous. Increase the aesthetic feeling, and welding aluminum argon welding pulse, then welding mouth is not good, and manually launched scales to beautiful. Therefore, no pulse, welding stainless steel is the opposite, duty cycle refers to the tungsten rod fired arc width, the width of the weld needs to be transferred on how much.
