Welding consumables

Welding wires and shielding gases

Choosing the right wire and gas has a key influence on weld quality.

Welding wires

The automatic wire feeder handles diameters from 0.6 mm to 1.6 mm.

ER70S-6 Carbon steel (copper-coated)
ER308L Stainless steel
ER5356 Aluminium and aluminium alloys
ERCuSi-A Copper and copper alloys

Shielding gases

Shielding gas protects the weld pool from oxygen and nitrogen in the air.

Argon All-round - steel, aluminium, copper
Nitrogen Stainless steel - prevents discolouration
Helium Thick aluminium - deeper penetration
Ar+He Mixtures - optimum performance

Welding torch

Ergonomic laser torch

Laser welding torch

Torch parameters

An ergonomic torch designed for many hours of work. The lightweight design minimises operator fatigue.

  • Weight: 0.8 kg - comfortable for the whole shift
  • Fibre optic cable: 10 m (option 15 m)
  • Built-in wire feeder - automatic, 0.6-1.6 mm
  • Dual safety button - prevents accidental start-up
  • Replaceable nozzle - quick tool-free change
  • Anti-slip housing - secure grip with gloves
Safety

Operator personal protection

Laser welding requires proper PPE. A Class 4 laser means protective equipment is mandatory.

PPE - Eye protection

OD6+ safety glasses

Dedicated safety goggles for work with 1064/1070 nm fibre lasers.

  • Optical density: OD6+ @ 1064 nm
  • Visible light transmission: >50%
  • Standard: EN 207 / EN 208
  • 3 pairs supplied with the welder
PPE - Hearing protection

Ear defenders

Hearing protection when working with high-power lasers.

  • Attenuation: SNR 25-32 dB
  • Adjustable headband
  • Soft ear cushions
  • Standard: EN 352-1
PPE - Hand protection

Welding gloves

Heat-resistant gloves for laser welding. Protect against UV/IR, spatter and heat.

  • Material: cowhide leather / Kevlar
  • Heat resistance up to 250°C
  • UV/IR protection
  • Standard: EN 12477
Safety systems

Laser welder safety features

Multi-level protection

Every welder is equipped with a complete safety system compliant with European standards.

  • Emergency stop button (E-STOP) - switches the laser off immediately
  • Contact sensor - laser active only in contact with the material
  • Two-hand interlock - both hands required to fire the beam
  • Lens temperature sensor - alarm and automatic shutdown on overheating
  • Open housing alarm - interlock when the service cover is removed
E-STOP emergency button

FAQ

Frequently asked questions

How often should protective lenses be replaced?
We replace protective lenses (windows) every 200-500 hours of operation, depending on welding conditions. If you notice a drop in laser power, burn marks or spots - replace them immediately.
Which wire should I choose for welding stainless steel?
For stainless steel we use ER308L wire (austenitic 304 steel) or ER316L (acid-resistant 316 steel). Diameter 0.8-1.0 mm for sheet up to 2 mm. Gas: argon 100%, flow 15-20 l/min.
Can I weld without wire?
Yes. The laser welder supports welding without filler material (autogenous). Ideal for thin sheet up to 1 mm with accurate edge fit-up.
Which shielding gas is best?
Argon 100% is the all-round choice. For aluminium thicker than 3 mm it is worth considering an argon+helium mixture. For stainless steel without discolouration - nitrogen as a backing (purging) gas on the root side.
Are the accessories compatible with all models?
Yes, the accessories are fully compatible with all WELDERSTAL laser welders (1500W, 2000W, 3000W). Please contact us before ordering focusing lenses.
