accidents. Wear a safety harness if working above ground.
-Do not drape cables over or around your body.
-Wear a full coverage helmet with appropriate shade (see ANSI Z87.1 safety standard) and safety glasses
while welding.
-Wear proper gloves and protective clothing to prevent your skin from being exposed to hot metals, UV and
IR rays.
-Do not overuse or overheat your welder. Allow proper cooling time between duty cycles.
-Keep hands and fingers away from moving parts.
-Do not point torch at any body part of yourself or anyone else.
-Always use this welder in the rated duty cycle to prevent excessive heat and failure.
1.4 Specific Areas of Danger, Caution or Warning
Electrical Shock
Electric arc welders can produce a shock that can cause injury or death. Touching
electrically live parts can cause fatal shocks and severe burns. While welding, all metal
components connected to the wire are electrically hot. Poor ground connections are a hazard, so secure
the ground lead before welding.
-Wear dry protective apparel: coat, shirt, gloves and insulated footwear.
-Insulate yourself from the work piece. Avoid contacting the work piece or ground.
- Do not attempt to repair or maintain the welder while the power is on.
-Inspect all cables and cords for any exposed wire and replace immediately if found.
-Use only recommended replacement cables and cords.
-Always attach ground clamp to the work piece or work table as close to the weld area as possible.
-Do not touch the welding wire and the ground or grounded work piece at the same time.
-Do not use a welder to thaw frozen pipes.
Fumes and Gases
-Fumes emitted from the welding process displace clean air and can result in injury or death.
-Do not breathe in fumes emitted by the welding process. Make sure your breathing air is clean and safe.
-Work only in a well-ventilated area or use a ventilation device to remove welding fumes from the
environment where you will be working.
-Do not weld on coated materials (galvanized, cadmium plated or containing zinc, mercury or barium).
They will emit harmful fumes that are dangerous to breathe. If necessary use a ventilator, respirator with air
supply or remove the coating from the material in the weld area.
-The fumes emitted from some metals when heated are extremely toxic. Refer to the material safety data
sheet for the manufacturer’s instructions.
-Do not weld near materials that will emit toxic fumes when heated. Vapors from cleaners, sprays and
degreasers can be highly toxic when heated.
UV and IR Arc Rays

- 3 -
The welding arc produces ultraviolet (UV) and infrared (IR) rays that can cause injury to your eyes and skin.
Do not look at the welding arc without proper eye protection.
-Always use a helmet that covers your full face from the neck to top of head and to the back of each ear.
-Use a lens that meets ANSI standards and safety glasses. For welders under 160 Amps output, use a
shade 10 lens; for above 160 Amps, use a shade 12. Refer to the ANSI standard Z87.1 for more
information.
-Cover all bare skin areas exposed to the arc with protective clothing and shoes. Flame-retardant cloth or
leather shirts, coats, pants or coveralls are available for protection.
-Use screens or other barriers to protect other people from the arc rays emitted from your welding.
-Warn people in your welding area when you are going to strike an arc so they can protect themselves.
Fire Hazards
Do not weld on containers or pipes that contain or have had flammable, gaseous or liquid
combustibles in them. Welding creates sparks and heat that can ignite flammable and
explosive materials.
-Do not operate any electric arc welder in areas where flammable or explosive materials are present.
-Remove all flammable materials within 35 feet of the welding arc. If removal is not possible, tightly cover
them with fireproof covers.
-Take precautions to ensure that flying sparks do not cause fires or explosions in hidden areas, cracks or
areas you cannot see.
-Keep a fire extinguisher close in the case of fire.
-Wear garments that are oil-free with no pockets or cuffs that will collect sparks.
-Do not have on your person any items that are combustible, such as lighters or matches.
-Keep work lead connected as close to the weld area as possible to prevent any unknown, unintended
paths of electrical current from causing electrical shock and fire hazards.
-To prevent any unintended arcs, cut wire back to ¼" stick out after welding.
Hot Materials
Welded materials are hot and can cause severe burns if handled improperly.
-Do not touch welded materials with bare hands.
-Do not touch TIG gun nozzle after welding until it has had time to cool down.
Sparks/Flying Debris
Welding creates hot sparks that can cause injury. Chipping slag off welds creates flying
debris.
-Wear protective apparel at all times: ANSI-approved safety glasses or shield, welder’s hat and ear plugs
to keep sparks out of ears and hair.
Electromagnetic Field
-Electromagnetic fields can interfere with various electrical and electronic devices such as
pacemakers.

- 4 -
-Consult your doctor before using any electric arc welder or cutting device
-Keep people with pacemakers away from your welding area when welding.
-Do not wrap cable around your body while welding.
-Wrap TIG gun and ground cable together whenever possible.
-Keep TIG gun and ground cables on the same side of your body.
Shielding Gas Cylinders Can Explode
High pressure cylinders can explode if damaged, so treat them carefully.
-Never expose cylinders to high heat, sparks, open flames, mechanical shocks or arcs.
-Do not touch cylinder with TIG gun.
-Do not weld on the cylinder
-Always secure cylinder upright to a cart or stationary object.
-Keep cylinders away from welding or electrical circuits.
-Use the proper regulators, gas hose and fittings for the specific application.
-Do not look into the valve when opening it.
-Use protective cylinder cap whenever possible
1.5 Proper Care, Maintenance and Repair
-Always have power disconnected when working on internal components.
- Do not touch or handle PC board without being properly grounded with a wrist strap. Put PC board in
static proof bag to move or ship.
-Do not put hands or fingers near moving parts such as drive rolls of fan
WAVE 315KD SERIES USE AND CARE
Do not modify the WAVE 315KD SERIES in any way. Unauthorized modification may impair the
function and/or safety and could affect the life of the equipment. There are specific applications for
which the WAVE 315KD SERIES was designed.
Always check of damaged or worn out parts before using the WAVE 315KD SERIES. Broken
parts will affect the WAVE 315KD operation. Replace or repair damaged or worn parts immediately.
Store idle WAVE 315KD. When WAVE 315KD SERIES is not in use, store it in a secure place out of
the reach of children. Inspect it for good working condition prior to storage and before re-use.
Notice: * If the welder continues to work too long time, the Heat Protection Indicator on the panel
would be on, indicating that the inner temperature rise inside the welder had exceed the
designed permitted temperature. At this time, stop the welding work, wait until the welder cooled inside and
the Heat Protection Indicator turned off, then continue to work again;
* Cut off the power switch and Argon valve, before leaving the welding place temporarily or after the
welding worked finished;
* Welders should wear canvas work clothes and welding face shield to prevent arc light and heat radiation;
* Put light-proof screen around the work area to prevent others influenced by the arc lights.
* Flammable, explosive items could not be put near the welding area;
* Every outlet of the welder should be connected and earthed correctly.

person suffocate, so please welding in a
well-ventilated environment
If you don't use, please close the cylinder
valve.
Electrical Shock
Do not check gas toward anyone.
Inspect all cables and cords for any exposed
wire and replace immediately if found.

S
hielding Gas Cylinders Can plode
Never expose cylinders to high heat
Keep cylinders away from welding
or electrical circuits and fixed good.
Keep people with pacemakers away from
your welding area when welding. Consult
your doctor before using any electric arc
welder or cutting device
It maybe interfere with radio, computers,
communications equipment and other
electronic equipment

Adjust gas pre flow time
Gas pre flow is to release the air in the gun
before welding, it can ensure gas purity.
Gas pre flow time according to the gas
hose length, normally less than 1s.
If continue welding, start the next welding before
gas valve stop, gas pre flow time will
automatically be ignored.

When you asjust, the digital
display show base current, unit
is A.
Base current
Base current adjust range is: minimum
value is min welding current. maximum
value is the same to current peak current,
if adjust peak current, base current will
proportional change.
Please according to the actual situation to
adjust base current.
When you asjust, the digital display
show pulse frequwncy parameter. Unit
is Hz.
Pulse frequency
Pulse frequency range is related to AC or DC.
When DC pulse welding, pulse frequency from 0.3Hz to
200Hz.
When AC pulse welding, pulse frequency from 0.3Hz to
5.0Hz.
When you adjust, the digital display
show pulse ratio, unit is %.
Pulse ratio
Pulse ratio means when pulse welding peak current time
percentage rates of the whole pulse period.
Pulse ratio related to frequency, When frequency more than
100Hz, pulse ratio fix on 50%, other from 10%-90%.
Open the cylinder valve, adjust the suitable gas flow, welding.
