The calculations are based on the Grenke leasing price list, which does not include insurance. Insurance is compulsory and the customer can either purchase their own insurance or take it out with the same contract. Leasing financing is only granted to companies with a valid business ID.
Lease period 12-72 months.
Leasing prices VAT 0.
Option to redeem at the end for your own final delivery price, which will be shown under the product and in the summary. The minimum final delivery price is 70€ VAT 0.
After placing an order with leasing financing, you will receive within 1-2 days by email the contracts for electronic signature.
If you wish to use your own insurance, the leasing company will require a certificate of insurance showing the following:
xTool MetalFab · Gas guide for the operator
Which gas cylinders and valves the xTool MetalFab laser welder and CNC laser cutter actually need – for welding, laser cutting and cleaning metal. Pressures in bar, with the machine's MPa values included.
OXYGEN 0.6 · WELDING 1–2 · CUTTING 6–12
This guide covers the xTool MetalFab 1200 W laser welder and CNC laser cutter, which welds, cuts and cleans metal – stainless steel, carbon steel, aluminium, brass and titanium – with a single fibre-laser system. Below you'll find the exact gases, pressures (in bar), regulators and controls that laser welding and metal laser cutting require.
All at 99.99% purity. The colour runs through the whole guide, so you can see at a glance which cylinder each job needs.
All-round gas. Welding, cleaning and cutting most metals. The most affordable inert-gas option.
Like nitrogen – and the only option for titanium (TC4). Denser shielding for the weld pool.
Only for cutting thick (2–10 mm) carbon steel and galvanised sheet. Needs its own nozzle and a low pressure.
Pressure in bar, the machine's set value (MPa) in small print. Flow in l/min. For thicker cutting, the SaveGas nozzle halves the pressure requirement.
Every cylinder needs a regulator that drops the 200 bar cylinder pressure to the working pressure. For fine adjustment you also add a flow or pressure regulator – always before the laser welder.
Flow (l/min) is easier to control than pressure when welding. The recommended choice for shielding-gas coverage.
15–30 l/minThe standard regulator fitted to the cylinder. Suitable for welding when you set pressure instead of flow.
1–2 bar · 0.1–0.2 MPaFor nitrogen, argon and compressed air. The adjustment range must reach well above the cutting pressures.
range over 12 bar · 1.2 MPaOxygen cutting of thick steel needs a very low and precise pressure. Precision 0.01 MPa.
0.6–0.7 bar · 0.06–0.07 MPaFor installation: an adjustable wrench and thread-seal tape (PTFE). Oxygen is the exception – no ordinary PTFE tape and no oil/grease on oxygen threads.
When cutting 2–10 mm carbon steel or galvanised sheet, you use oxygen and a double-layer nozzle with an extension tube. The pressure is 0.6–0.7 bar – tens of times lower than in other cutting (6–12 bar). An ordinary regulator won't do this.
Plan A: proportional valve set to 0.6–0.7 bar + flow regulator fully open. (E.g. SMC ITV2050-312BL.)
Plan B: a precision pressure valve that adjusts to 0.01 MPa accuracy – no proportional valve needed.
Safety: oxygen accelerates combustion dramatically. No oil, no grease, only oxygen-rated parts. Open the valve slowly.
Connection tip: the welder's gas inlet is a 10 mm push-to-connect fitting. European cylinder valves differ, and each gas has its own standard – confirm the fitting with your gas supplier (in Finland e.g. Woikoski or Linde/AGA).
For laser welding the shielding gas is nitrogen (N?) or argon (Ar), purity 99.99%, flow 15–30 l/min (or pressure 1–2 bar). Argon is mandatory when welding titanium. The same gas also works for manual laser cleaning.
Thin 0.2–1 mm metal cuts at over 6 bar (nitrogen, argon or compressed air). Thicker stainless, aluminium and brass need over 12 bar – or just 6 bar with the SaveGas nozzle. Thick 2–10 mm carbon steel is cut with oxygen at a very low 0.6–0.7 bar.
Yes. Dried compressed air can replace nitrogen or argon as the cutting gas, saving on cylinder costs. It requires a compressor (rated over 10 bar, output over 200 l/min) and an air dryer. See the xTool MetalFab air compressor and dryer unit.
For welding and cleaning a flow regulator (15–30 l/min), for cutting a pressure regulator whose range reaches over 12 bar, and for oxygen cutting of thick carbon steel a proportional or precision pressure valve (accuracy 0.01 MPa) for the low 0.6–0.7 bar. Each cylinder also needs its own regulator.
The xTool MetalFab 1200 W is available in Finland from Nettiverstas with Finnish-language product support. Instalment and leasing are also available for companies. See the xTool MetalFab metal workshop in the online store.
The wire is chosen by material: ER308L for stainless, ER70S-6 for carbon steel and galvanised sheet, and 6061 for aluminium. The wire diameter is matched to the sheet thickness. See all welding wires and accessories.
The xTool MetalFab 1200 W welds, cuts and cleans metal with a single machine – Finnish-language product support, instalment and leasing. For a compressed-air setup, see also the air compressor and dryer.
