Weldy Booster EX3 Hand Extrusion Welder

The Weldy Booster EX3 is a 3000 W hand extrusion welder at 6.9 kg delivering 2.5 kg/h with 3 mm rod and 3.6 kg/h with 4 mm rod for HDPE, LDPE, LLDPE, and PP sheet up to 15 mm – featuring a three-handle system with lockable drive button, rear rotating push handle, and side-mount handle configurable left or right, double-sided rod intake, motor protection with digital display, high-quality barrel extruder, easy-change welding shoes, internal air guide with air-heated screw, and a durable transport case – designed for standing-posture extrusion welding on civil engineering geomembranes, agricultural membranes, construction sheeting, and tank and container construction applications.

Standing-Posture Hand Extrusion Welding for Civil Engineering and Membrane Fabrication

The operational distinction between the Weldy Booster EX2 and EX3 is not power output – both operate at 3000 W – but body. The Booster EX3 is specifically built longer to support standing-posture extrusion welding: the type of welding work where the operator stands upright, advances along the seam, and guides the extruder forward in a walking working motion that progresses the weld bead along the joint line for extended seam lengths. This is the working posture of geomembrane liner welding on civil project sites, agricultural pond liner installation, construction membrane lap seam repair, and large-format plastic sheet fabrication – where the joint runs for metres rather than centimetres, where the operator’s body is above the work surface rather than inside a vessel looking down at a joint, and where the ergonomics of the extruder handle system determine whether the operator can maintain consistent bead placement quality across the full seam length without the posture fatigue that a short, compact extruder design imposes when used in the standing-forward-progress welding mode.

The Booster EX3’s three-handle system is the primary ergonomic feature that its longer body enables. The lockable drive handle provides the primary grip and trigger control for the walking weld run. The rotating rear push handle at the back of the extruder provides the forward drive guidance point from which the operator pushes the machine along the seam from behind – the natural standing-posture operation stance for forward-progress extrusion welding. And the side-mount handle configurable on left or right provides the additional lateral guidance point for cross-body seam runs and angled approach positions. Together, these three handles make the Booster EX3 adaptable to the varied seam direction, surface angle, and operator body position combinations that civil geomembrane installation, membrane repair, and construction sheet welding presents across active project sites in Oman and the GCC. For civil contractors, agricultural infrastructure developers, construction waterproofing teams, and PE/PP fabrication operations requiring a capable, ergonomically considered extrusion welder for standing-posture membrane and sheet welding work, the Booster EX3 provides the correctly sized, correctly configured instrument at a price point that reflects Weldy’s accessible Leister Group positioning.

Booster EX3 Technical Capabilities and Standing-Posture Welding Features

• Longer Body Design Specifically for Standing-Posture Operation: The Booster EX3 is built longer than the compact Booster EX2 – producing a body length and centre-of-gravity position that is better suited to the standing, forward-progress extrusion welding posture of geomembrane seam work, membrane installation, and large-format sheet welding. The longer body places the welding shoe further in front of the operator’s hands, enabling a more natural, upright walking weld stance that reduces the stooped posture that shorter extruder bodies impose on standing-progress welding work.
• Three-Handle System for Sustained Ergonomic Control: The lockable drive handle at the primary grip position allows the operator to lock the drive in the active welding state without sustained trigger pressure – reducing hand fatigue across extended seam runs. The rotating rear push handle provides the rearward guidance point for standing-posture forward-progress operation – the natural propulsion point when guiding the extruder along the seam from behind in the walking welding stance. The side-mount handle, configurable on the left or right side as required, provides lateral guidance control for cross-body seam approach angles and varied working positions across complex membrane installations.
• 3000 W Output at 2.5 kg/h (3 mm Rod) and 3.6 kg/h (4 mm Rod): The 3000 W heating system delivers 2.5 kg/h with 3 mm rod and 3.6 kg/h with 4 mm rod – measured with PE – providing the volumetric throughput that geomembrane T-joint and repair welding, membrane lap seam reinforcement, and tank panel joint fabrication on PE and PP sheet up to 15 mm thickness requires for productive progress along the joint runs that membrane and construction sheet applications present.
• Motor Protection with Digital Display: The motor protection system monitors the drive mechanism against overload conditions and presents operating status on the digital display – providing the operator with process visibility and motor protection that open-loop extrusion welding without display feedback cannot offer. The digital display enables the operator to confirm that the extruder is operating within correct parameters during active welding, and the motor protection function prevents drive damage from sustained overload during intensive welding sessions.
• Double-Sided Welding Rod Intake – Left or Right: The Booster EX3 accepts welding rod from either the left or right side – enabling the operator to load rod from whichever side the current working position on the membrane surface, slope, or installation geometry makes accessible. This bilateral intake is relevant on large-area membrane installations where the position of the rod coil relative to the seam line changes as the operator advances along a seam or transitions between seam directions across the liner area.
• High-Quality Barrel Extruder with Easy-Change Welding Shoes: The high-quality barrel extruder design provides the consistent melt quality and bead consistency that PE and PP extrusion welding on geomembranes and construction membranes requires – with easy-change welding shoes enabling quick shoe swap between joint geometry types or when shoe wear requires replacement, minimising the downtime associated with shoe changes during active welding programmes without specialist tooling or machine disassembly.
• Suitable for PE and PP Sheet up to 15 mm Thickness: The Booster EX3 is specified for tank and container construction on PE and PP sheet up to 15 mm thickness – covering the wall thickness range of standard HDPE and PP tank panels, agricultural structure sheeting, and civil construction sheet materials used in container fabrication and membrane installation applications across Oman and the GCC within a single extruder configuration.
• Locking Key for Continuous Welding: The locking key maintains the drive in the active welding state for continuous seam runs without the operator sustaining trigger pressure throughout – enabling the operator to direct full grip and guidance attention to the extruder positioning and bead placement accuracy that consistent seam quality requires on long geomembrane and membrane seam runs, rather than dividing attention between trigger maintenance and guidance control.
• Internal Air Guide for Compact Working Profile: The internal air guide routes pre-heated air within the extruder body to the welding shoe – maintaining the compact external body profile that the standing-posture welding stance requires by avoiding external guide hoses and fittings that would increase the effective working cross-section of the extruder at the nozzle end where joint access is most critical on membrane surface welding work.
• Durable Transport Case Included: The Booster EX3 is supplied with a durable transport case protecting the extruder, welding shoes, and accessories from dust, debris, and mechanical damage during transport to and storage on active civil project sites and production facilities – maintaining accessories in clean, ready-to-use condition between welding sessions and protecting the extruder from the site environment that geomembrane installation and outdoor membrane welding work presents.
