Antra AH7-860-0000 Auto Darkening Welding Helmet Huge Viewing Size 3.86X3.5″ Wide Shade Range 4/5-13 Great for TIG MIG/MAG MMA Plasma, Grinding, Solar-Lithium Dual Power, 6+1 Extra lens covers

Bigger is all the time better

More covering area, better viewing angle, more flexible

• Luxury viewing size of 13.5 SQI provides comfort working zone, which is twice larger when compared to entry level lens
• Easier to see awkward spots than smaller viewing size helmets, more flexible to be used in different scenarios.

Clearer Lens with Blue Lights Suppression

Clearer welding puddles and pools, more sensitive and 4 premium sensors

• Blue light reduction lens (Optical Class 1/1/1/2) provides clear viewing and blue light protection, and helps to lay solid beads.
• 4 Redundant sensors ensures high reliability and durability.
• Quicker response time and more flexible when used in applications with partially blocked view.

One helmet , multiple processes

Versatility is another great asset of AH7-860 along with its reliable performance

This unit is working on most of ARC related applications including but not limited to:

• Gas Tungsten Arc Welding (GTAW), sometimes called Tungsten Inert Gas (TIG) welding, DC or AC
• Gas Metal Arc Welding (GMAW), on occasion referred to by its sub-types Metal Inert Gas (MIG) Welding or Metal Active Gas (MAG) welding
• Flux-cored Arc Welding (FCAW or FCA)
• Shielded Metal Arc Welding (SMAW), sometimes called Manual Metal Arc welding (MMA or MMAW), flux shielded arc welding (stick welding)
• Plasma Cutting (PAC)
• Plasma Arc Welding (PAW)
• Grinding

(Note: Different settings may be required for each application.)

Antra’s Interference Suppression Technologies enables AH7-860 to:

• Detects and response consistently on DC welding arc as little as 2 Amps
• Minimize false triggering in industrial Metal-halide lights, on higher sensitivity setting if not facing lights directly
• Minimize false triggering in sun lights, on higher sensitivity if not facing sun directly

Easy to adjust settings

Most of the time of thumb, start with a shade that is too dark to see the weld zone. Then, go to a lighter shade which gives a sufficient view of the weld zone without going below the minimum.

• Grinding Mode: Set the switch to Grind, the lens will stay on shade 4, will not be activated by any arc.

WARNING: Switch “Weld” mode to avoid accidental flashes.

• Shade Adjustment: First set the SHADE RANGE the use of the range selector switch, “5-9” or “9-13”, then use the Shade dial to set the desired shade numbers.

5-8 is great for some low amp application and small current plasma cutting jobs.

• Delay Regulate: Dark to Clear Delay, to avoid glow flashes from the hot bead. Turn clockwise, the delay time will be increased.
• Sensitivity Regulate: Controls how sensitive the sensors are responding to welding arc. Proper setting can avoid false triggering from adjacent arc whilst ensures auto darkening when needed. Turn clockwise, the sensitivity will be increased. Set the sensitivity highest, and decrease if there false triggering exists.
• All internal settings is great for people who want to work in limited spaces
