Vertical Electrogas Welder
Electrogas welding machine (EGW) is a highly-efficient automatic welding equipment manufactured to realize closed-loop weld current. It is designed with optional ways of mounting, including permanent magnet adsorption, electro magnet adsorption, vacuum absorption with a vacuum sucker, switch permanent magnet adsorption, making it convenient to assembly and disassembly. This electrogas welding machine is widely used for welding of thick plates in industries like oil, chemical, blast furnace, shipbuilding, etc.
1. The liquid level of the molten pool can be automatically controlled.
2. Wire extension can be automatically adjusted.
3. The travel carriage is small in size, light in weight, as well as flexible and convenient to use.
4. Modular design of this vertical electrogas welder facilitates upgrade of the machine.
5. Welds of this electrogas welding machine are done in single pass, no inter-pass cleaning.
6. Welding plate thickness: 10mm~50mm.
Main Parts of Electrogas Welding Machine

C. EGW Welding Control Box
|EGW welding control box is designed for EGW heavy-load welding carriage.
|It has combined complex automation control system with field operation requirement to satisfy all needs of EGW-3G electrogas welding process.
|Remote display of real-time welding current and voltage.
|Indicator light of travel carriage.
|Remote adjustment of real-time welding current and voltage.
|Real-time adjustment of wire extension.
|Remote control of cater-cooled wire feeding, and arc striking and extinguishing.
|Automatic closed-loop control of carriage travelling.
|Spare manual control of carriage walking.
D. Linear Oscillator
|The linear oscillator of our vertical electrogas welder is used together with the welding control box. It is powered by the welding control box with no additional power supply requiremnt.
|It can form an integral operation interface that enjoys stable signal when used together with the control box through air plug. This linear oscillator can also be used separately.
|Real-time stepless adjustment of oscillation speed, oscillation amplitude and dwell time.
|Automatic centering d assembling welding torch.
|It facilitates the assembling of welding arc.
E. Power Source and Wire Feeder
F. Type of Groove
Thickness ≤ 24mm
Thickness > 24mm
