Weller 6970 Operating Instructions Manual
MODEL 6970 HEAT GUN OPERATING INSTRUCTIONS
HEAVY DUTY HEAT GUN
The Weller Model 6970 has been designed to handle jobs
far beyond the capabilities of a conventional-size heat
gun.
It has the power and capacity to master a wide range of
heavy-duty assignments, including molding and welding
plastics, softening and forming plastic laminates, paint
stripping, curing large volumes of epoxies, heat-shrinking
cables and softening floor tiles and putty.
Weighing only 28 ounces, the 6970 is surprisingly light for
a heavy-duty heat gun, yet is engineered and ruggedly
constructed to withstand the demands of long and
constant use. You will discover that its handle is
comfortable to hold, even over extended periods, and
remains cool at all times.

WARNING: This product, when used for soldering and similar applications, produces chemicals known to the State of
California to cause cancer and birth defects or other reproductive harm.
WARNING: To reduce the risk of fire or electric shock, connect to grounded outlet; do not expose to rain or
moisture, store indoors; read instructions before using.
IMPORTANT THINGS TO REMEMBER
The 6970 has a variable 3-position switch: up to 700°F/off/up to 1000°F. Make sure the switch is in the center (off) position
before plugging the gun into the required AC power outlet.
Correct heat/air speed setting is determined by the type of work and pace most comfortable for the operator.
Be aware that the amount of heat available for the job drops off sharply as the distance between the nozzle outlet and work
surface is increased. Consequently, for tougher jobs, and to accomplish work more rapidly, set the gun at 1000°F and move
it in closer. However, always maintain the minimum of 1/4" clearance between the nozzle and the work surface to prevent
possible damage.
Also, never direct the heat toward glass or other heat sensitive materials as cracking or breakage may occur.
NOTE: If air flow is blocked to nozzle, causing overheating, the gun will turn off and come back on when it has cooled. DO
NOT leave gun unattended when it has stopped, since it will restart and could cause fire or injury.
MAKE SURE ITS GROUNDED
This heat gun comes with a 3-conductor cord and a 3-prong plug for proper grounding to prevent possible electric shock.
Always plug the gun either directly into a ground outlet or into the correct size 3-wire extension cord (see chart).
If either the unit or the 3-wire extension cord is plugged into an ungrounded (2-prong) outlet, make certain that you use a
grounding adapter and follow the instructions supplied by its manufacturer. Observing these precautions will assure full
protection for the operator against possible electric shock.
CHECK YOUR EXTENSION CORD
Determine that its the proper length and that the wire size is marked WA for outdoor use (if so used) and that its U.L.
(Underwriter Laboratories) approved. If used in Canada, it should be CSA approved.

ALWAYS OBSERVE THESE SAFETY RULES
FOR A SAFE WORK AREA
Keep the work area clean and uncluttered.
Keep visitors, especially children, away from the work area.
Maintain proper lighting for maximum visibility.
FOR OPERATOR SAFETY
Wear safe clothing, avoid jewelry or other loose fitting items.
The 6970 produces up to 1000°F of flameless heat at the nozzle, so keep face, hair, hands, clothing, etc., out of
the air stream.
Connect to a grounded outlet to avoid the risk of fire or electric shock. Do not expose the unit to rain or moisture.
Never operate the gun on its side on a bench. Always hold it securely in the hand.
Wear safety glasses while operating the unit. Non-skid footwear and rubber gloves are also recommended for
outdoor use.
Never use a heat gun when overly tired or after taking any kind of drug.
Avoid using this tool in or near flammable liquids or explosive atmospheres of gas, vapor or dust.
Dont touch the nozzle while operating. Wait for cool-down period of 3-5 minutes after the unit is turned off.
Keep the nozzle at least 1/4" from the work surface to ensure unrestricted air flow.
Always make sure that the air gun is clean and free of moisture before operating.
Check to see that both intake and outlet openings are not clogged or restricted.
FOR PROTECTION OF THE HEAT GUN
After using, position the gun with the nozzle upward to allow residual heat to rise.
Give your heat gun the care you would any fine precision instrument. Dont carry it or swing it by the cord, or
unplug the cord by yanking or pulling on the heat gun.
Keep the cord away from sharp edges, heat, water, oil and solvents. Make it a habit to inspect it periodically.
FEATURES
The 6970 Heat Gun is operated by a 3-way low/off/high switch conveniently located at the trigger position. Heat flow is
1000°F and 700°F at the nozzle, deliverable in seconds. For additional operator convenience, the unit has a 6 ft. 3-wire
cord, plus a ring for suspending it over a work area.
SPECIFICATIONS
750 watts (max.), 120 Volts AC (only).
High setting - 1000°F at air flow of 3000 FPM*/7.7 CFM**
Low setting - 700°F at air flow of 2700FPM/6.9 CFM
*FPM (feet per minute)
**CFM (cubic feet per minute)
Hidden areas such as behind walls, ceilings, floors, soffit boards and other panels may contain flammable materials
that could be ignited by the heat gun when working in these locations. The ignition of these materials may not be
readily apparent and could result in property damage and injury to persons.
When working in these locations , keep the heat gun moving in a back-and-forth motion. Lingering or pausing in one
spot could ignite the panel or the material behind it.
