All right. It can automatically adjust the calorific value, so the temperature can be kept constant. The air gun part of the welding table has the advantages of high control accuracy and strong temperature linearity. Using this advantage, the temperature can be controlled digitally and analogously, so the accident of welding element damage caused by temperature error can be reduced. The welding frame of this brand adopts the top-end 857 skeleton type, and the heating core of the skeleton has a series of advantages such as long service life, strong temperature controllability and high heating power.
