VUP: Vertical Up Welder high heat input welding with Lincoln self shielded NR431 Inner shield wire.
AVW-Multi pass: low heat input multiple pass (FCAW / dual shield) arc welding machine, specially designed for field work construction of special steel brands (such as low-temperature steel and stainless steel). AVW leaflet 10.22.2021
EGW (electrogas (arc) welding machines) which is also know as a (AVW) automatic vert welder are high efficient automatic welding equipment which achieves closed-loop control of carriage lifting via current feedback; Welding joint one-step forming thickness is 50mm, mainly used for thick plate single pass vertical seam welding in petroleum, chemical, blast furnace and ship building industries.
The EGW Single Pass Vertical Welder is a high productivity automatic vertical welding machine which uses real time closed-loop monitoring of the welding arc to accurately locate, control and adjust the welding head in the weld joint via arc current feedback and automatic carriage travel. This is used to complete single pass welds in material from 9 to 36mm thick but can also be used to complete thicker plate welds of up to 70mm when welding on both sides of the joint. This machine is used for vertical plate welding in the storage tank and many other applications.
A standard EGW-V electro gas welder can with a single or double sided frame (recommended) to house all the necessary components along with the operators for high deposition code quality vertical welding operation in any part of the storage tank.

Vertical welder model we offer EGW-V, EGW-P, EGW-Jack-UP, EGW=Electro Gas Welder which is also know as a Vertical Up Welder (VUP), is a single pass Vertical-Up welder (VUP), AVW-multi pass, AVW-Jack-UP, AVW automatic vertical welder.
Electrogas welder | EGW – P are single pass unmanned vertical welding machines
EGW (electrogas (arc) welding machines) (Electrogas Welder) which is also know as a (AVW) automatic vert welder are high efficiency automatic welding equipment which achieve closed-loop control of carriage lifting via current feedback; Welding joint one-step forming thickness is 50mm, mainly used for thick plate single pass welding in petroleum, chemical, blast furnace and ship building industries.
Compact non operator carrying vertical welder that runs on shells for max flexibility
Eliminates limitation on plate width for conventional vertical welders
Suitable for general heavy wall vertical welding for tanks (repairs and construction), vertical cylindrical structures (piles, offshore jackets, chimneys etc) and vertical panels
Economical but sufficiently robust for heavy duty welding operation.
Specific models welding on inclined surface (eg. tank roof, inclined piles)

Vertical Up Welder, VUP, built as a column type Electrogas welder for welding carbon steel storage tanks in warm climates, AVW automatic vert welder
Developed for the Lincoln single pass Mechanical Vertishield process which usually uses the Lincoln NR431 Innershield wire. The All Time VUP operates at the same principle of electrogas welding as the All Time EGW, but it is made of a column & saddle structure instead of a fully enclosed frame design. Welder without the requirement of gas shielding, the All Time VUP is a simple & reliable option for high deposition tank vertical welding for wall thickness over 15mm.
This VUP Vertical Up Welder A.K.A (AVW automatic vert welder) is an open column type design for use with self shielded Lincoln NR431 inner shield wire for high heat input welding system in warm climates.
