.2. Equipment Details
.2.1 Overview
This machine is a private welding head designed for tube / plate automatic TIG welding. It
can be used to a variety of tube / plate automatic welding. It can weld carbon steel, stainless
steel and tube / plate joint of other forms, including the flush end connection, stretching fillet
connection. Two welding forms of feeding wire and self-melting can be used.
The machine has vector automatic arc length control system. Through collecting the arc
voltage signal, the feedback principle automatically correct electric arc voltage, to maintain
stable space between the tungsten electrode and welding surface. The function of automatic arc
length control can also be turned off. Through the 2 multifunction controller knobs, the space
between the tungsten electrode and welding surface can be manually intervened to meet the
needs under different conditions.
The welder adopts fast install and remove modular design, which is easy to maintain and
install. It has dual-loop water cooling system and long sustained working hours. The perfect gas
protection system ensures a good protection of weld puddle during the whole process of
welding.
The welder‘s movement is adjusted by dual-mode of pulse and constant speed, which
greatly increases the depth of fusion, effectively improves the welding efficiency, makes weld
lines appearance uniform and beautiful, and need no grinding or cleaning. The welder adopts
high load rate design and sustained working hour is long. Under the guarantee of a good
process, the repair rate is very low. The welder can greatly improve the process repeated
welding. Also the welder has good control power matching, can precisely achieve all position
TIG tube / plate welding and achieve the desired welding effect.
