PLC Control SanRex power source IGBT tube to tube welding machine automatic tig orbital welder

About us

Kehui technology was organized in 1996, as the leading company in the welding and heat treatment field. It concentrates on providing solution and recommendation to clients, hence, we attempt to customize our product relates to clients’ requirements. By the rich experience in such area, we may design and produce various type of product, such as tube-tube and tube-tube sheet, and other type automatic welding machine which successfully be used in petrochemical, manufacturing and boiler industry.

Application

Application Industry: Applicable for industries such as medicine and chemical, food, biological engineering, refrigeration equipment, electronic equipment, instruments and apparatuses.

Applicable Scope:Automatic TIG welding (without wire) of thin-walled tube for carbon steel, alloy steel, stainless steel and titanium alloy.

Function:The power supply/control system supplies and controls the welding parametersaccording to the specific weld program created or recalled from memory..The specific weld program ( can store 100 groups)are setup by our engineer according to your welding situation.

You also can setup your weld specific program through resisitive touch screen. Our machine can tore 100 groups of weld parameter.The sreen pictures are display as belows:

Functions and Features

1. KHGC has many types of welding machine head, which can meet different requirements of consumers. Users can choose one or more welding head according to the tube diameter and the used space.

2. KHGC series is suitable for welding of tube to tube, tube to elbow, tube to flange, tube to value body and tube to unions

3. Because of its extremely small dimensions,the KHGC series is the perfect solution for application with tight access restrictions.

4. Fill the chamber with shield gas before welding can provide good protection and form the beautiful appearance and high quality of weld seam.

5. The duplex clamp inserts makes the workpiece orient correctly without the orient sport welding .

6. Through on-site testing,it proves that the welding machine head is more effective and reliable with Maxon motor and Maxon gears.

7. All welding parameters fully programmable.up to 100 programmes storage. All operational process is controlled by PCL system with its touch screen.

8. PLC control system, control is accurate, reliable and strong anti-jamming capability, with LCD touch screen, all English input, direct and convenient.

9.Adopt SanRex IGBT inverter control dc pulse power ID - 3001 TP, guarantee high welding efficiency and strong arc stability, Weld bead molding beautiful.

10.Mandatory water cooling system, equipped with stainless steel tank, not be limited by field water hydraulic water source etc conditions, cooling fully, reliable convenient;

11.KHGC equiped with the printer can print the welding parameters . Selecting the automatic mode, the parameters will be automatically printed when each welding is completed.
