Auto Variable Welding Helmet Manufacturer,Supplier and Exporter in India

Product Code : EL-AELE-12927
Jlab Export is a leading Auto Variable Welding Helmet Manufacturer,and suppliers in India

This auto-darkening welding helmet watches for the arc with two sets of photo sensors. When they pick up arc light, the filter switches from shade 4 to the dark shade the welder has preselected. The choices are 9, 10, 11, 12 and 13. An integrated solar panel powers the filter, and its UV and IR protection is permanent.

Welding Practicals with an Auto-Darkening Helmet

Because the filter stays at shade 4 until the arc strikes, a trainee can see the joint and place the electrode with the helmet already down. This helps in the first arc-striking and bead-running exercises on an Arc Welding Machine. Beginners with a fixed dark lens often lose their start point as they nod the helmet down.

The same helmet serves later practicals on the TIG Welding Machine and the MIG Welding Machine. Before each job the trainee sets a dark shade to suit the process and current, and the instructor checks the setting.

Frequently Asked Questions

Which dark shade should I preselect?
Choose by process and welding current. Low-current work is usually done at the lighter end, shade 9 or 10, and heavy-current welding at 12 or 13. If the weld pool still looks too bright to watch in comfort, go one shade darker.

Does the helmet need a battery?
The filter takes its power from the integrated solar panel on the helmet. Keep the panel clean and do not cover it with tape or a cap, so it can pick up light whenever the helmet is in use.

Am I protected from UV and IR before the filter darkens?
Yes. The filter gives permanent UV and IR protection, so it is there at shade 4 as well as after the switch to the dark shade. Darkening cuts the visible glare of the arc to a level the eye can work with.

Why does it have two sets of sensors?
Two sets give the helmet more than one view of the arc. If a hand, the torch or the job blocks one set, the other can still pick up the arc light and switch the filter.

Can I use it for gas welding or brazing?
Torch work needs a much lighter filter than the dark range of shade 9 to 13. For oxy-acetylene welding and brazing use Gas Welding Goggles fitted with a suitable shade lens instead.
