How to adjust the parameters of medium frequency welder during welding? [DCS03]
Dec 20,2023
The welding parameter adjustment of medium frequency welding machine is usually decided by the material and thickness of welding base metal. First step is to determine the shape and size of electrode end face. And then select parameters of electrode pressure, welding current and electrifying time preliminarily.
Medium frequency welding setting is generally divided into two styles. Either big welding current with short welding time, or small welding current with long welding time.
In general, for the first trial, you can start with a small current since it is uncertain to know the apt current value to use. Gradually try from a small current to a large current until there is sputtering. And then the current will be reduced till no sputtering. Check the single welding spot of tension, nugget diameter and depth of penetration is in line with the requirements or not. The appropriate adjustment of current or welding time is followed until the requirements are met.
As the plate thickness increases, the current needs to be increased, too. The way to increase the current is generally to adjust the voltage (When resistance is at a certain value, the higher the voltage, the greater the current) , or to increase the current in a certain state of power-on time, or increase the heat input, so as to achieve good welding results.
