FUNCTIONALITY: In general, the MHR WELD SHIELD is ideal and intended to perform tac-and-stitch welds and some continuous welding utilizing FCAW (Flux Cored Arc Welding) & GMAW (MIG) welding machines. The MHR WELD SHIELD can perform flat, vertical, and horizontal welds. Do to safety and design The MHR WELD SHIELD must not be used for overhead welding.
The MHR WELD SHIELD is both a protective device and a weld viewer. The MHR WELD SHIELD protects and directs sparks away from the welder and utilizes standard protective lenses and shaded weld lenses to protect the welder from harmful light emissions. The MHR WELD SHIELD is used solely for protecting the welder and DOES NOT provide any protection for the area surrounding the welder and any person or thing that is near the welder.
Additional protection to the surrounding area and any person’s near the area shall be provided to protect others from sparks, light emissions etc.; using the standard precautions and individual safety protection equipment necessary to safeguard anybody in the area, and the area where the welding is performed. Disclaimer: The MHR WELD SHIELD is not intended to replace or substitute any safety equipment that is still necessary to protect your face, hands and other parts of the body before you perform any welding. Please read carefully and follow all the Safety & Precaution Tips included with each MHR WELD SHIELD so you can perform welds safely and protect yourself from mishaps that commonly are known during the welding process. When used wisely and with caution The MHR WELD SHIELD can cut your helmet time in half.
STEP 1: SETTING UP YOUR WELD GUN INTO THE MHR WELD SHIELD:
Provided with your MHR WELD SHIELD is a separate Base Plate. This separate Base Plate is attachable and removable to the MHR WELD SHIELD. Its primary use is to help you set up the weld gun to the MHR WELD SHIELD. The Base Plate allows you to secure your weld gun to the weld shield and insures that the tip of your weld gun is sitting at the proper distance in relation to the bottom of the MHR WELD SHIELD. Also, you can store the MHR WELD SHIELD and the weld gun into the Base Plate when not in use. You can also hang the assembly from the convenient hang hole located on the Base Plate.
Assemble and attach the MHR WELD SHIELD to the Base Plate. Carefully align and insert the 3 sides of the MHR WELD SHIELD into the 3 gripping holders on the Base Plate. Push down until the MHR WELD SHIELD seats completely into the grips and is flat to the bottom of the Base Plate.
Set the MHR WELD SHIELD and Base Plate assembly on top of a steady table or hard surface.
Insert your weld gun tip and neck thru the clamp and hole in the back of the MHR WELD SHIELD. (Make sure the clamp is open enough for the weld gun tip and neck to pass thru. If not back off on the clamp screws to open the clamp until you have the necessary clearance.)
After your weld gun is inserted, feed the weld gun all the way into the weld shield until the weld gun tip makes contact to the bottom of the Base Plate. There is a step channel in the Base Plate and this is where the tip of the weld gun should make contact.
While holding the weld gun firmly, straight and steady keep the weld tip against the Base Plate step channel. Use your other hand to tighten the screws on the clamp. Tighten the clamp screws firmly and securely until there is no more movement of the weld gun neck. If this procedure is followed correctly the weld gun is straight and there is no movement in the clamp and the weld tip is in contact with the Base Plate step channel. (If not repeat steps d & e)
You can now carefully remove the Base Plate from the MHR WELD SHIELD by slowly lifting the back of the MHR WELD SHIELD from the back grip first, and then lift the rest of the MHR WELD SHIELD from the side grips separating it from the Base Plate. Put Base Plate aside.
At this point your weld gun has been setup and mounted to the MHR WELD SHIELD with the correct distance in relation to your weld gun tip.
GO TO STEP 2. Setting up the MHR WELD SHIELD to weld.
STEP 2: Setting up the MHR WELD SHIELD to weld.
The MHR WELD SHIELD comes with 3 weld lenses. The 3 weld lenses are stacked together and assembled in this order: a clear protective lens with one laminated side placed at the bottom, a shaded filter lens and/or auto darkening lens placed in the middle and a clear protective lens placed on the top of the stack (non-laminated). The 3 stacked lenses assembly are inserted into the open cavity located in the front of the MHR WELD SHIELD. Carefully slide the lenses assembly into the front cavity and feed the assembly all the way into this cavity until the assembly rests against the back stop and cannot go in anymore.
Locate the Black Pin fastener. Insert Black Pin fastener into the hole located on the top front of the MHR WELD SHIELD. Carefully, push down on Black Pin fastener into the hole until a snug fit is felt. Do not push the Black Pin Fastener all the ways down. Leave some of the pin and the head exposed so it can be grabbed and removed easily as necessary. The black pin fastener is meant to be removable and its purpose is to hold the lenses assembly in place and keep them from falling out of the cavity of the MHR WELD SHIELD.
Only, if you have performed both STEP 1 & STEP 2 completely & successfully you will be ready to weld with the MHR WELD SHIELD. If you did not follow or have missed any portion of the steps please do not attempt to weld! You could put yourself or others at risk of danger and injury. Go back and make sure all is complete.
GO TOSTEP 3: Welding with your MHR WELD SHIELD.
STEP 3: Welding with your MHR WELD SHIELD
Please read the SAFETY & PRECAUTIONS TIPS guide that came with your MHR WELD SHIELD before performing any welding! This will guide you to taking the correct steps and what precautions and safety equipment you will need in addition to using the MHR WELD SHIELD. Not reading and following the SAFETY & PRECAUTIONS TIPS guide can result in serious harm and injury to yourself and others around you.
Your MHR WELD SHIELD has a Weld Viewer Area located at the top. This viewer is for the welder to see the weld area and the weld being deposited at the work area. The welders’ eyes are protected from harmful light emissions by either a “Passive Shaded Filter Lens” such as a Shade #10 colored lens or an “Auto Darkening Lens” located within the viewer of the MHR WELD SHIELD.
When the welder is ready he/she locates the area to be welded and holds the MHR WELD SHIELD over that area with the tip of the weld gun ready to strike the area. Looking into the viewer the welder strikes the first arc and the welding process has started. The welder’s eyes focus on the viewer and continues to weld with a dragor pull technique. The MHR WELD SHIELD has very good visibility when welding and you can see the actual weld wire coming out of the nozzle as it deposits the media. The MHR WELD SHIELD is designed to direct sparks and gases away from the welder. Sparks and gases will emit out and exit at the front and bottom of the MHR WELD SHIELD. Remember the MHR WELD SHIELD is used solely for protecting the welder and DOES NOTprovide any protection for the area surrounding the welder and any person or thing that is near the welder. Additional protection to the surrounding area and any person’s near the area shall be provided to protect others from sparks, light emissions etc.; using the standard precautions and individual safety protection equipment necessary to safeguard anybody in the area, and the area where the welding is performed.
When maintaining your MHR WELD SHIELD, be sure to check all its parts thoroughly on a regular basis. Wipe out the dust and any debris from the inside of your MHR WELD SHIELD after each use. Use water, lens solution or wipes to clean its surfaces. Try to use a soft tissue or micro fiber cloth to dry it. When lenses get too dirty and compromise your ability to see, remove lenses from the MHR WELD SHIELD to clean them. First, remove the Black Pin fastener and then tilt down slightly and carefully pull the lenses out thru the front cavity.
Step 1: Cleaning Lenses- Lenses usually may be clogged with particles of any kind or dusts. Clean lenses thoroughly so that you can see clearly while using them. Use a soft brush to dust off the lens at first. Use water, lens solution or wipes to clean its surfaces. Try to use a soft tissue or micro fiber cloth to dry it.
Take note that the MHR WELD SHIELD protective lens layers, particularly those that function to protect you against the IR and UV rays, are quite delicate that you must clean them in a more delicate manner. Basically, the lenses should be wiped out right after using it. Use water, lens solution and a micro fiber cloth to clean its surfaces. Try to use a soft tissue or micro fiber cloth to dry it.
Step 2: After examining and cleaning the lenses, check for any cracks or chips on the lenses as they can break and might hurt you. Inspect all parts of the MHR WELD SHIELD. Try to see if there are a few or several parts that are defective or not working at all because you have to replace them at once, otherwise it will compromise your safety.
Step 3: Check your MHR WELD SHIELD for dents or cracks. Find out if there are any screws that are missing, and try to replace them at once. Loose screws can also cause harm eventually. Use a screwdriver to tighten the screws. Step 4: Store your MHR WELD SHIELD in a proper way. Choose a good storage spot as this can help prolong its lifespan. Pick out a stable, solid and covered area where the MHR WELD SHIELD can be stored very securely without any possibility of falling or getting any dents or bruises. The lens must be taken into careful consideration as it is very sensitive, so place your MHR WELD SHIELD in such as a way that the lens is well protected and does not touch any surfaces to prevent it from getting scratched. Moreover, avoid keeping the MHR WELD SHIELD in a place where the temperature is very humid as this will encourage the growth of bacteria.

SAFETY & PRECAUTIONS TIPS: (FCAW & GMAW)
Safety Glasses - Always wear Z87.1 approved safety glasses with side shields, or goggles, to protect your eyes from flying particles
Clothing - Protective clothing needed for welding includes general fire resistant clothing, safety glasses, shoes, gloves, and leathers. Burns are the most common injury to welders due to sparks landing on the skin. Welding arcs are very intense and can cause burns to skin and eyes with just a few minutes of exposure. Because of its durability and resistance to fire, wool clothing is suggested over synthetics. Synthetics should never be worn because it melts when exposed to extreme heat. Cotton can be worn if it is specially treated for fire retardation. Avoid rolling up your sleeves or pant cuffs, because sparks or hot metal could deposit in the folds. Also, wear your pants outside your work boots, not tucked in, to keep particles from falling into your boots.
Shoes - Leather boots with six- to eight-inch ankle coverage are the best foot protection. Where heavy work is done, safety-toe protection boots should be worn. Metatarsal guards over the shoe laces can protect them from falling objects and sparks
Gloves - Heavy, flame-resistant gloves (from materials such as leather) should always be worn to protect your hands and wrists from burns, cuts and scratches. As long as they are dry and in good condition, they will offer some insulation against electric shock.
MHR Weld Shield and Arc Rays - It is essential that your eyes are protected from radiation exposure. IR radiation can cause retinal burning and cataracts. IR can usually be felt as heat. UV radiation, which cannot be felt, can cause an eye burn known as "Welder's Flash." This condition may not be apparent until several hours after exposure. It can cause extreme discomfort and can result in swelling, fluid excretion and temporary blindness. Normally, "Welder's Flash" is temporary, but repeated or prolonged exposure can lead to permanent injury of the eyes. The general rule of thumb is to choose a filter too dark to see the arc and then move to the next lighter setting without dropping to below the minimum recommended rating. The chart below serves as a guide on the minimum required shade protection. UV radiation can also burn exposed skin. This process is similar to getting sunburn from overexposure to the sun. Long exposure to arc rays without protection can lead to second and third degree skin burns. Repeated overexposure to ultraviolet radiation is a known cause of skin cancer.
Noise and Hearing Protection - Earplugs and earmuffs keep metal sparks and airborne particles from entering your ear canal and protect your hearing from the effects of excessive noise.
