Welding Helmet

Model: Gt 2000227/201

Introduction

Auto-darkening Welding Helmets are designed to protect the eyes and faces from spark, spatter, and harmful radiation under normal welding conditions.
The auto-darkening filters automatically change from dark to light state when welding arc disappears.
WARNING!
PLEASE READ THIS MANUAL CAREFULLY BEFORE USING

Product Features

1. Dark to clear delay adjustment, Operator can vary the time for the filter to return to clear state.
2. Sensitivity adjustable can make the operators more convenient while operating.
3. WELDING/GRINDING can be selective
4. The helmet utilizes high performance solar cell as power supply and has  1 replaceable 3V lithium batteries as power back-up. And the battery life is raisedto a new limit. Under normal welding conditions, users can expect a battery has a lifetime of more than 5000 hours.
5. Variable shade from DIN 5 to 13 is adjusted at the turn of a shade knob.
6. The ultra high performance of UV/IR Auto-Darkening filters provide full protection for the user’s eye & face a against UV/IR radiation during the entire welding process, even in the light state. The UV/IR protection level is up to Shade16(DIN) at all times. It makes welders feel comfortable in welding working.

OPERATING INSTRUCTION

1. Before Welding 1.1 Ensure that the internal and external protective films are removed from the lenses.
   1.2 Check that the batteries have sufficient power to operate the helmet. The filter cartridge can last for 5,000 working hours powered by the lithium batteries and solar cells. When the battery power is low, the Low Battery LED indicator will light up. The filter cartridge lens may not work correctly. Recharge or Replace the batteries (see Maintenance Battery Charge or Replacement).
   1.3 Check that the arc sensors are clean and not blocked by dust or debris.
   1.4 Check for headband tightness before each use. 1.5 Inspect all operating parts before use for signs of wear or damage. Any scratched, cracked, or pitted parts should be replaced immediately before using again to avoid severe personal injury.
   1.6 Select the shade number you require at the turn of a shade knob (Seeing the Shade Guide Table). Finally, be sure that the shade number is the correct setting for your application.
   Shade Guide Table Note: SMAW-Shielded Metal Arc Welding.
   MIG(Heavy)-MIG on heavy metals.
   . MIG(Light)-MIG on light alloys.
   TIG GTAW-Gas Turgten Arc (GTAW)(T1G).
   SAM Shielded Semi-Automatic Arc Welding.
   PAC-Plasma Arc Cutting

2. Sensitivity The sensitivity control is set according to the welding process and ambient light.
   2.1 Low Setting- suitable for high amperage welding and welding in areas with high levels of natural sunlight.
   2.2 Medium Setting – suitable for most indoors and outdoors welding.
   2.3 High Setting- suitable for low amperage welding and welding in areas with low light conditions, especially for low amperage argon-arc welding.

3.  Self-Check
   3.1 Set the filter shading number anywhere between DIN9-13.
   3.2 Press the TEST button to see if it switches to the dark state.
   3.3 Release the Test button to check that the filter returns to the bright state.

4. Grinding Mode The welding helmet can also be used to protect the face during grinding. Push the Grind button, Switching to Grind mode will prevent the filter cartridge from darkening when bright sparks are created.

5. Delay Time Delay time refers to the time the cartridge filter is set to change from the dark to bright state after welding stops. The delay can be adjusted up to a one second delay.
   5.1 The minimum delay is set between 0.1 to 0.2 seconds, suitable for spot or short welds.
   5.2 The maximum delay time is set between 0.85 to 1.0 second, suitable for heavy current welding or when visible light is produced.
   5.3 Selections between minimum and maximum are suitable to most indoor and outdoor welding operations.

Adjust the headband

6.1 Adjusts headband for proper depth on the head to ensure correct balance and stability. (See No.1).
6.2 Adjusts the distance between the face and the lens.To adjust, Press down the looker to unlock, adjust the positioning looker moved to another location slot,forward or backward. (Both sides must be equally positioned for proper vision, (See No.2)
6.3 Turn the adjusting knob located on the back of the headband left or right to desired tightness.(See No.3)
6.4 Shift the segmental plate with different positioning hole to adjust the window angle for clear view. (See No.4)
Numbers on the adjustment slides indicate set position so both sides can be adjusted equally.

Recharge or Replace battery

When the battery power is low, the Low Battery LED indicator will light up. The filter cartridge lens may not work correctly. First please Recharge the battery. If the charge function not working or battery is dead, Replace the batteries (see Maintenance Battery Charge or Replacement.)
Noted: Toughened mineral filter oculars/ADF shall only be used in conjunction with a suitable backing ocular.
Begin and continue your welding work
After all is ready and finish the test now you can do your welding work.

Maintenance

8.1 Cleaning and disinfection: Clean filters’ surfaces regularly; do not use strang cleaning solutions. Always keep sensors and solar cells clean using a clean lint-free tissue/cloth. You can use of alcohol and cotton to wipe.
8.2 Use neutral detergent to clean the welding shell and headband. Replace outer and inner protection plates periodically.
8.3 Don’t immerse the lens in water or any other liquid. Never use abrasives,sol- vents or oil based cleaners.
8.4 Don’t remove the auto-darkening filter from the helmet. Never try to open the filter.
8.5 when low battery light is on, the filter cartridge lens may not work correctly, please charge it immediately.
—-you can connect to a USB DC power supply via type C wire to get a fast charge.
— you can put it in a sun light to get it charged slowly.
— you can replace the old cell battery CR2450 by a new one to use it immedi- ately, refer to Fig on page. Warning! always make sure the polar connection “+” & “-“; always keep the battery out of reach by children.
