SAFETY PRECAUTIONS
Follow these precautions carefully. Improper use of any welder can
result in injury or death.
1. ONLY CONNECT WELDER TO A POWER SOURCE FOR WHICH IT WAS
DESIGEND. The specification plate on the welder lists this information. When welding outdoors
only use an extension cord intended for such use.
2. ONLY OPERATE WELDER IN DRY LOCATIONS and on cement or masonry floor. Keep
area clean and uncluttered.
3. KEEP ALL COMBUSTIBLES AWAY FROM WORK SITE.
4. DO NOT WEAR CLOTHING THAT HAS BEEN CONTAMINATED with grease or oil.
5. KEEP CABLES DRY AND FREE FROM OIL AND GREASE and never coil around
shoulders.
6. SECURE WORK WITH CLAMPS or other means; don't over reach when working.
7. NEVER STRIKE AN ARC ON A COMPRESSED GAS CYLINDER
8. DON'T ALLOW THE INSULATED PORTION OF THE ELECTRODE HOLDER TO
TOUCH THE WELDING GROUND WHILE CURRENT IS FLOWING.
9. SHUT OFF POWER AND UNPLUG MACHINE WHEN REPAIRING OR ADJUSTING.
Inspect before every use. Only use identical replacement parl.
10. FOLLOW ALL MANUFACTURER'S RULES on operating switches and making
adjustments.
11. ALWAYS WEAR PROTECTIVE CLOTHING when welding . This includes: long sleeved
shirt(leather sleeves), protective apron without pockets, long protective pants and boots. When
handing hot materials, wear asbestos gloves.
12. ALWAYS WEAR A WELDER'S HELMET WITH PROTECTIVE EYE PIECE when
welding. Arcs may cause blindness. Wear a protective cap underneath the helmet.
13. WHEN WELDING OVERHEAD, BEWARE OF HOT METAL DROPPINGS. Always
protect the head, hand, feet and body.
14. KEEP A FIRE EXTINGUISHER CLOSE BY AT ALL TIMES.
15. DO NOT EXCEED THE DUTY CYCLE OF THE MACHINE. The rated cycle of a welding
machine is the percentage of a ten minute period that the machine can operate safely at a given
output setting.
16. KEEP ALL CHILDREN AWAY FROM WORK AREA. When storing equipment, make
sure it is out of reach of children.
17. GUARD AGAINST ELECTRIC SHOCK. DO not work when tired. Do not let body come
In'contact with grounded surfaces.

Ip and Ib and their continuous time tp and tb can be regulated according to requirements of the
process. The amplitude value of electric current changes periodically with certain frequency in
case of the pulse current , molten bath will be formed in the workpiece and the molten bath
will be solidified in case of base current. The welding seam is formed by reciprocal overlaps .
Welding heat input can be controlled by regulating pulse frequency, pulse current amplitude,
size of base current, continuous time of pulse current and base current and therefore the
welding seam, size and quality of the zone influenced from heat can be controlled.
(2) Advantages and application scope of pulse argon gas tungsten arc welding
a. Precisely control the size of the bath inputting heat to workpiece to increase penetration
resistance of molten seam and preservation of bath. It is easy to obtain even fusing deepness.
This process is specially applicable to omni - bearing welding of sheet and formation to be
done with both sides through one side welding.
b. Heating and cooling of each welding point is very fast . Therefore, the process is applicable
for the workpiece with great difference of heat conductivity and thickness.
c. Pulse arc can obtain greater fusing deepness with lower heat input. Therefore, under the same
condition, the zone influenced from welding heat and deformation from welding
can be reduced. This is very important for sheet and ultra -thin sheet welding.
d. Fast cooling of the bath metal and short duration time of high temperature during welding can
reduce cracks caused to the thermo-sensitive materials during welding.
(3) Selection of welding parameters
Except for pulse current and the width time(width ratio) as well as pulse frequency,welding
parameters of pulse argon gas tungsten arc welding are same as general tungsten DC argon
arc welding. Pulse current increasing means electric arc can obtain greater penetration ability.
But too much current can cause local melting of tungsten electrode. Generally, welding

current required for DC tungsten argon arc welding or greater current is used. Arc holding current
( ie base current) influences cooling and crystallizing of the metal in the bath. The range is
determined by performance of the welding materials.When sheet is welding, smaller arc
holding current (base current) is usually used in order to reduce welding through and
deformation. When pulse width ratio (holding time of pulse current and base current) is
selected, both the heat input and features of pulse welding should be considered. Usually, it can
be selected between 30 -60%. Selection of pulse frequency(periodical change time of pulse
current) mainly depends on thickness of sheet and welding speed and operation custom of the
operator should be also considered.
