PWH1000 Auto-Darkening Solar Powered Four Sensor Welding Helmet
Instructions For Use
• The helmet comes fully assembled. Before starting to weld, adjust the helmet to fit the user properly and set for
delay time, sensitivity and shade level.
• Adjusting The Fit Of The Helmet
The overall circumference of the headband can be made larger or smaller by rotating the knob on the back of
the headband. ( See adjustment "Y" in fig. 1) This can be done while wearing the helmet and allows just the right
tension to be set to keep the helmet firmly on the head without it being to tight.
• If the headband is riding too high or too low on your head, adjust the strap which passes over the top of your
head. To do this, release the end of the band by pushing the locking pin out of the hole in the band. Slide the two
portions of the band to a greater or lesser width as required and push the locking pin through the nearest hole (See
adjustment "W" in fig. 1)
• Test the fit of the headband by lifting up and closing down the helmet a few times while wearing it. If the
headband moves while tilting, readjust it until it is stable.
• Adjusting Distance Between Helmet And Face
Step 1: Undo the block nut (See"T" in fig. 1) to adjust the distance
between the helmet and your face in the down position. It is important
that your eyes are each the same distance from the lens. Otherwise
the darkening effect may appear uneven.
Step 2: Retighten the block nut when adjustment is complete.
• Adjusting The Viewing Angle Position

• Selecting Shade Level
Select the shade level that your process requires by referring to the
"Guide For Shade Numbers" for settings. Turn the shade control knob on
the inside of the helmet (fig. 3) to the shade number required.
• Selecting Delay Time
When welding ceases, the viewing window automatically changes
from dark back to light but with a pre-set delay to compensate for
any bright afterglow on the work piece. The delay time/response can
be set to long (0.1 secs) or short (1.0 secs) as you require, using
the delay control knob on the back of the shade cartridge. (See fig. 3)
• Sensitivity
The sensitivity can be set to "high" or "low" using the sensitivity dial
knob on the back of the shade cartridge. The "high" setting is the
normal setting for everyday use. When the operation of the mask
is disturbed by excess ambient light or another welder is close by,
use the "low" setting. (see fig. 3)
