Flexible and multi-application roof welding machine LST-WP4

Short description:

➢ The new generation roof hot air welding machine WP4 provides more application diversity.

➢ The welding of high-quality thermoplastic waterproofing membranes (PVC, TPO, EPDM, ECB, EVA, etc.) can be quickly welded in roof gutters, gutter edges, parapet edges or other narrow spaces. The maintenance-free brushless motor and WP4 enhanced version give it high performance and durability, and the overall performance is far better than similar products.

➢ One machine for multi-scenario welding, wide application range and high welding efficiency.

➢ Adopt closed-loop control technology (digital display + main board control) to ensure the stability of parameters and the overall welding quality.

➢ Small and flexible, light weight and high power.

➢ The welding width is 40mm, which can meet the customized service of different widths in small batches.

➢ Accept small orders.

➢ Satisfy small batch customization services.

➢ Spare parts

➢ Including 1 additional 230v/4000w heating element, 5 fuses (for circuit board), 1 heat shield, 1 steel brush for cleaning the welding nozzle, 1 steel operating handle, 1 additional counterweight, 1 One screwdriver and four wrenches, one English manual.

➢ Inner packaging

➢ The machine is locked in a metal suitcase with screws.

➢ Use plastic blister packaging parts, such as parts bags, to avoid collisions during transportation.
