Weldy Energy HT1600 (120 V) for US Buyers: Which Kit Should You Choose?
Quick answer
The Weldy Energy HT1600 ships as a bare gun and as three catalogued kit variants; in the 120 V / US plug line Weldy lists the bare gun, the plastic welding kit and the overlap welding kit — and the shrinkage kit is not currently catalogued as a 120 V / US plug version. One article lines up the gun, the catalogued kits and which one fits tarp covers, banners and small plastic welding jobs done on a 120 V US supply.
For a US buyer the question is rarely which gun — it is whether the kit ordered carries a US-plug 120 V article number, and whether the accessories that ship with it match the job. The HT1600’s bare gun plus its three catalogued kits share the same accessories; the kit choice is set by the work, the variant choice by the supply.
In a US shop the gun has to plug into the supply, and the kit has to match the work. The HT1600 line is wide enough that buyers often end up looking at the bare gun, the plastic kit, the overlap kit and the shrinkage kit — and not knowing which are catalogued for a 120 V US supply. This guide lines those options up, calls out the verified 120 V / US plug article numbers and leaves the choice to the application.
Voltage selection itself is covered in our 120 V vs 230 V version article. The focus here is the option question once the voltage has been decided.
What the Weldy Energy HT1600 Is
The Weldy Energy HT1600 is a 1,600 W hand-held hot air gun for plastic welding and shrinking. It runs stepless from 40 °C to 700 °C, weighs 0.99 kg, moves 240 l/min of air and produces 2,600 Pa of static pressure. It carries a brush motor with a ceramic heating element, accepts nozzles on a Ø 31.5 mm connection and ships in a cardboard pack with a manual in 28 languages.
The standard article is sold either as a bare gun or inside one of the factory kits built around the same gun. The kits change what is in the case; the bare gun ships the gun only.
Bare Gun + Verified Kit Options
| Option | Gun | Nozzles in the case | Roller | Case | Weldy article (120 V / US plug) |
|---|---|---|---|---|---|
| Bare gun | HT1600 | — | — | Cardboard pack | 123.898 (verified in Weldy 120 V / US plug catalog — store SKU 148.004) |
| Plastic welding kit | HT1600 | Ø 5 mm tube nozzle (147.250) and 4 mm speed welding nozzle (146.740) | — | Durable plastic case | 120.886 (verified in Weldy 120 V / US plug catalog — store SKU 120.989) |
| Overlap welding kit | HT1600 | 40 mm wide-slot nozzle (124.777) and 20 mm wide-slot nozzle (124.772) | 40 mm silicone pressure roller | Durable plastic case | 120.885 (verified in Weldy 120 V / US plug catalog — store SKU 120.889) |
| Shrinkage kit | HT1600 | 40 mm and 20 mm overlap nozzles, plus a reflector nozzle | — | Durable plastic case | Not catalogued as a 120 V / US plug version at the time of writing — availability to be checked on the product page or with our technical team |
The overlap kit and the plastic kit ship with a set of spare carbon brushes (125.810) for the blower motor. The bare gun ships in a cardboard pack rather than a case.
The bare gun and the three kits are listed in the same hot air gun collection and in the Weldy collection.
120 V vs 230 V: The Version Column
Three of the options above — the bare gun (123.898), the plastic welding kit (120.886) and the overlap welding kit (120.885) — are currently listed by Weldy as 120 V / US plug versions. Weldy previously offered 230 V shrinkage kits under articles 125.015 and 125.016, but those versions are currently marked discontinued. If shrinking is the primary application, check the current product range with the supplier before ordering.
The 120 V version is the one ordered for a 120 V US supply; the 230 V version is ordered for a 230 V grid. The two share the same temperature range and the same accessory line; they are not field-convertible.
| Item | What the 120 V / US plug column means |
|---|---|
| Supply | Listed for 120 V US supply (the specific receptacle and plug are set on the product page) |
| Frequency | 50/60 Hz, common to both versions |
| Plug | US plug as supplied — confirmed on the product page before the order ships |
| Generator / extension | Site-specific: sized to deliver the rated current at the gun — left to the user’s installation and the Weldy manual |
| Adapter use | Not part of the supplied configuration — a 230 V unit with a travel adapter is not the 120 V version |
The full reasoning for picking the 120 V version over a converted 230 V unit is in our 120 V vs 230 V article. The two articles are linked so US buyers land on the options view after they have decided the voltage.
The 120 V HT1600 is built and listed for 120 V US supply; the article number on the box identifies which voltage and plug is supplied.
Which Kit Fits Which Job
The catalogued kits cover three different jobs in a US shop. The kit choice is set by the job; the voltage is set by the supply.
- Tarps, truck covers, banners, vinyl membrane patches. The overlap welding kit (Weldy article 120.885, store SKU 120.889). Two wide-slot nozzles sit flat on the overlap, and the 40 mm silicone roller dresses the seam warm.
- Plastic tanks, pond liners, HDPE/PP/PVC fabrication and repair. The plastic welding kit (Weldy article 120.886, store SKU 120.989). The 4 mm speed welding nozzle feeds filler rod into a prepared joint; the 5 mm tube nozzle reaches into corners, fittings and tight details. Where the approved welding procedure calls for extrusion welding or greater material deposition, use a separate hand extruder.
- Heat-shrink film, packaging, labels and tube shrinking. Weldy previously offered an HT1600 shrinkage kit, but the 230 V versions currently shown by Weldy are marked discontinued and no 120 V / US plug version is currently listed.
- Owning just the gun, then picking nozzles as jobs come up. The bare gun (Weldy article 123.898, store SKU 148.004). The accessories range carries every nozzle and roller that fits the Ø 31.5 mm connection.
The kits are not interchangeable in use. The overlap kit ships the roller that the overlap welding job calls for; the plastic kit ships a tube nozzle and a speed nozzle that the plastic welding job calls for. Buying the wrong kit means buying the wrong tool for the seam.
Overlap Kit for Tarps, Covers and Banners
The overlap kit is the kit tarp-and-cover welders reach for first when they ask about the HT1600. In the 120 V / US plug catalog it carries Weldy article 120.885 (store SKU 120.889). It ships the gun, two wide-slot nozzles and a 40 mm silicone pressure roller.
The 40 mm wide-slot nozzle (124.777) sits over a wider overlap and covers more working area in a pass. The 20 mm wide-slot nozzle (124.772) reaches narrower overlaps, edge details and confined geometries where the wider nozzle does not sit flat. Both fit the Ø 31.5 mm connection on the HT1600. The seam geometry and the working width set which size is the better fit on the seam being welded; how that maps to a given material is set by the membrane or material manufacturer and the project procedure.
The 40 mm silicone pressure roller in the case presses the two warm surfaces together as the seam cools. Roller widths are compared in our 30 mm vs 40 mm silicone pressure rollers article.
Where a patch needs to be held in place before the welding pass, the tacking setup is a two-part arrangement. The Ø 8.0 mm tacking nozzle (147.248) mounts through the Ø 31.5 mm tubular nozzle (147.250), so both parts are ordered together. Compatibility in full is set out in our Weldy hot air gun nozzle compatibility guide.
The overlap kit ships the gun, both wide-slot nozzles, the 40 mm roller and spare brushes; the case arrives with the kit so the parts travel together.
Plastic Kit for HDPE, PP and PVC Fabrication
The HT1600 plastic welding kit carries Weldy article 120.886 in the 120 V / US plug catalog (store SKU 120.989). It ships the same gun plus the two nozzles a thermoplastic welder typically reaches for first. The 4 mm speed welding nozzle (146.740) feeds a filler rod into a prepared joint. The Ø 5 mm tube nozzle (147.250) reaches into corners, fittings and tight details where the speed nozzle does not fit. Spare carbon brushes (125.810) for the blower motor are in the case.
For manual filler-rod welding on tank, liner, boat and pipe details, the plastic welding kit is the relevant HT1600 setup. Where the approved welding procedure calls for extrusion welding or greater material deposition, move to a hand extruder; our hand extrusion welder collection covers those applications.
Other Hot Air Options Around the HT1600
Where the spec does not quite fit, the rest of the Weldy hot air line sits either side of the HT1600.
- HT1600D — the digital-display twin of the HT1600. 1,600 W, temperatures from 40 °C to 620 °C stepless on an LCD, an integrated cool-down cycle and a 1.2 kg weight. Where the project procedure calls for set-and-hold temperature, the D is the matching unit. The HT1600D overlap kit ships the same overlap kit layout with the digital gun.
- HT3400 — higher-output hand gun for heavier membrane work. Where the project demands more output than the HT1600 gives, the move is up the line rather than across.
All three are listed in the hot air gun collection and in the Weldy collection.
Service Parts and What to Keep in the Drawer
The HT1600’s brush motor has a wear part: the carbon brush. Keeping a spare set in the drawer stops a wear-out from stopping the job. The brushes in the kit (125.810) are sized to the gun. Wear signs and replacement steps are in our carbon brushes article.
Heating elements, brushes and other consumables live in the Weldy accessories collection. Going there rather than to a non-OEM source keeps the parts matched to the gun.
How to Confirm a Setup
- Match the gun to the supply. Order the 120 V version for a 120 V US supply, the 230 V version for a 230 V grid. The two are not interchanged by adapter.
- Match the kit to the job. Overlap kit for tarps, covers, banners; plastic kit for HDPE/PP/PVC fabrication; bare gun when only the gun is needed. For shrinking applications, check Weldy’s current product range rather than assuming an HT1600 shrinkage kit is still available.
- Match the nozzle to the seam. The Ø 31.5 mm connection fits the nozzles in the case; wider or narrower seats call for the matching nozzle in the accessories collection.
- Take the temperature from the material. Welding values come from the membrane or material manufacturer’s instructions for the sheet and the joint; trial weld a sample of the material before the production pass.
- Carry a 1-year warranty. The HT1600 and its kits are covered for 1 year; replacement parts and lifetime technical support are available from our technical team.
A field check does not replace the trial weld used to establish the setup; any production pass on a different roll or gauge is a reason to re-check the settings against the manufacturer’s instructions.
Where to Start
- Start from the supply. A 120 V US supply means the 120 V / US plug column on the product page is the one to order.
- Start from the job. Tarps and covers pull to the overlap kit; tank and liner work pulls to the plastic kit; for shrinking applications, check Weldy’s current product range rather than assuming an HT1600 shrinkage kit is still available.
- Start from the nozzle. The kit ships the nozzles its job calls for; anything outside the case comes from the accessories list.
- Start from the procedure. The material or project procedure, not the gun, sets the temperature and the weld sequence for the production pass.
The Weldy Energy HT1600 (120 V) and its kit options are collected on our hot air gun page and our Weldy collection.
