Electric Drill Complete 114.753: The Drive Unit That Keeps Your Weldy EX2/EX3 Feeding

Quick Answer: What Is Part 114.753?

The Electric Drill Complete (SKU 114.753) is the drive unit of the Weldy Booster EX2 and EX3 hand extruders — the motor assembly that drives the screw and keeps the rod feeding steadily through the barrel. Despite the name, it is not a handheld drilling tool: it is a replacement part inside the machine. When feed pressure drops, speed becomes uneven, or the motor shows its age, this is the component to check first.

How the Screw Drive Works Inside the EX2/EX3

The Booster EX2 and EX3 are 3000 W hand extruders for PE and PP. A welding rod of ø 3–4 mm enters from either side and is carried by the screw drive, which conveys the molten material continuously through the heated barrel and out through the welding shoe. Consistent screw-drive feed helps maintain a stable and uniform extrusion bead. Irregular drive performance can contribute to inconsistent material flow and bead formation.

5 Signs the Drive Unit Needs Attention

• Rod feed slips or jerks — the rod is pulled in unevenly instead of smoothly.
• Output drops below the rated figure (1.5–2.2 kg/h on the EX2; 2.5–3.6 kg/h on the EX3) with the same settings.
• Unusual noise from the drive area — grinding or clicking during feeding.
• Overheating or brush wear — visible sparking or a burning smell from the motor housing.
• Inconsistent weld beads — voids, thin sections or a wavy bead profile from unsteady feed.

If several of these appear together, check the carbon brushes and the feed path first. If the problem persists, the complete 114.753 drive unit may need further inspection or replacement.

Service & Replacement: Leave the Swap to a Technician

The drive unit sits inside the machine housing and is connected to the motor wiring, so replacement is a service task rather than a routine adjustment. We recommend having the exchange carried out by a qualified service technician, or contacting Weissenberg's technical support for guidance — correct installation matters for long-term feed reliability.

Keep the Drive Healthy: Maintenance Basics

• Carbon brushes — a spare set (115.069) is included with the EX2/EX3; inspect and replace them when worn.
• Keep the feed path and screw area free of dust and rod debris; a blocked channel makes the motor work harder than it should.
• Do not force the rod — the drive is designed to feed by itself; pushing can overload the mechanism.
• Store the extruder in its transport case, dry and dust-free.

Choosing the Right Replacement Part

An extruder is only as reliable as its drive. When replacing the drive unit, make sure the part matches the manufacturer's specification for the EX2/EX3 — rod diameter, feed rate and mounting all need to line up with the machine design. If you are unsure whether 114.753 fits your unit, send us your machine's serial or article number and our technical team will confirm compatibility before you order.
