The W200 is a DC welder and generator in one machine: 40 to 200 amps of welding current plus 3.6kVA of auxiliary power, driven by a Honda GX390. Welding current is regulated mechanically through an 8x2 position selector rather than electronically, which is a deliberate choice — fewer components to fail, no electronics to damage on site, and a machine that keeps working in conditions that would stop an inverter welder. At 170A on a 60% duty cycle it will run a 4mm electrode continuously rather than in short bursts.
Emissions Compliance
Stage V certified. Every model in this range meets the Stage V non-road mobile machinery emissions standard, which is a condition of entry on many local authority, London and principal contractor sites.

Key Features
- Welder and generator in one — 200A of welding plus 3.6kVA auxiliary, so lights, grinders and tools run from the same machine.
- Mechanical current regulation — an 8x2 position selector rather than electronics — fewer things to fail and nothing to damage in wet or dusty conditions.
- 170A at 60% duty cycle — sustained welding rather than short bursts, which is what separates a working welder from a hobby machine.
- Honda GX390 — air cooled, recoil start, and serviceable anywhere.
- 110V and 230V auxiliary outlets — 1x110V 32A for site tools and 1x230V 16A for everything else, both IP44 protected.
- 80kg dry weight — portable by two people or a van tail lift, without needing plant to move it.
Suitable Applications
The W200 is bought for welding where there is no mains supply: agricultural and estate repair, pipeline and fabrication work, site repairs, fencing and gates, plant and vehicle maintenance, and rural and remote work generally. The auxiliary outlets make it a working power source between welds, which for a mobile repair operation means one machine instead of two. Mechanical regulation suits exposed conditions where an inverter welder would be at risk.
How to Use
- Site the machine in the open air on firm level ground, clear of flammable material.
- Check engine oil and fuel, and inspect the welding leads and electrode holder.
- Select the welding current range on the 8x2 selector to suit the electrode and material.
- Start the engine and let it stabilise before striking an arc.
- Weld, observing the duty cycle — 170A at 60% means six minutes welding in every ten.
- Allow the machine to run unloaded to cool before shutting down.
Warning: Never operate a generator indoors, in a partially enclosed space, or anywhere exhaust can reach an occupied area. Exhaust contains carbon monoxide, which is colourless, odourless and fatal. Welding also produces fume and intense ultraviolet radiation: use proper eye protection, screening and ventilation.
Safety Information
- Operate only in the open air, well clear of doors, windows and air intakes.
- Never refuel a hot or running engine.
- Do not connect to a building's fixed wiring without a correctly specified changeover arrangement.
- Use only leads and connectors rated for the outlet, inspected before each use.
- Keep fuel and flammables away from the exhaust and hot surfaces.
- Earth the set in accordance with the site electrical arrangement.
- Use a welding mask of the correct shade, and screen the arc from other people.
- Ensure adequate ventilation for welding fume, which is a health hazard in confined spaces.
- Check the work return clamp is connected directly to the workpiece, not through bearings or machinery.
Inspection and Maintenance
Check oil, fuel and the air filter daily, and inspect the socket panel, leads and residual current protection before each use. Service intervals follow the engine manufacturer's schedule by running hours. Generators used as work equipment fall under PUWER, and the outlets and any supplied leads fall within the site inspection and test regime. Inspect welding leads, the electrode holder and the return clamp before each use — damaged insulation on a welding lead is both an electrical and a fire risk.

Frequently Asked Questions
Q: What thickness can it weld?
40 to 200A covers general fabrication and repair with common electrode sizes. The 170A at 60% duty cycle figure is the one that matters for sustained work.
Q: What does 60% duty cycle mean?
At 170A you can weld for six minutes in every ten, with four minutes for the machine to cool. Exceeding that repeatedly will trip the thermal protection.
Q: Can I run tools from it at the same time as welding?
It has 3.6kVA of auxiliary power, but drawing heavily on the auxiliary outlets while welding at high current will affect both. Use them alternately where possible.
Q: Does it come with welding gear?
No. The welding kit (LY000A00007) with mask, lens, gloves, brushes, hammer and 5m cables is ordered separately.
