will help to prevent risks and hazards.
1. Always be alert when using this product, so that
you can recognise and handle risks early. Fast
intervention can prevent serious injury and dam-
age to property.
2. Switch off and disconnect from the power sup-
ply if there are malfunctions. Have the product

if necessary, before you operate it again.
Residual risks
Even if you are operating this product in accordance with
all the safety requirements, potential risks of injury and
damage remain. The following dangers can arise in
connection with the structure and design of this product:
1. Damage of the eye's retina resulting from the ultra-
violet radiation of the arc or by sparks.
2. Burns caused by touching the hot workpiece or
electrode.
3. Risk of fire.
Welders Instructions
TIG 200S PULSE pulse inverter welder uses inert
gases (Argon) as the protection medium for the arc,
using high frequency or high pulse to do the gas ion-
ization and melt metals by the arc, made between
the tungsten electrode and work piece, to reach
the welding purpose. It can give fast good com-
pensation for power grids fluctuation, and can con-
trol accurately for various welding process. Thus, it
is smooth soft, little splash and easy appearance of
weld. In the welding of high strength steel and low
carbon steel, stainless steel, alloy steel materials can
easy get good appearance of weld.
The characteristics of the argon arc welding
machines is:
• The tungsten is not melting, arc is stable, easy to
control welding quality during welding.
• It can do wire filling, also without wire filling, is
suitable for welding sheet, also suitable for thick
plate.
• The arc heat concentration, the work piece de-
formation less than the mig machines and MMA
machines.
• Suitable for all position welding.
• Especially suitable for welding sheet below 3
mm, also can get good welding quality for less
than 1 mm thick sheet.
• Soft arc, arc concentricity is good, fillet welding is
easy, and reliable positioning welding.

TIG 200S PULSE series inverter dc pulse argon arc
welding machine adopts the advanced inverter tech-
nology, using international advanced IGBT as a con-
verter, supplemented by special development control
circuit, make the whole machine has high reliabil-
ity, fast dynamic response, stable arc characteris-
tics. This series welding machine has: dc pulse argon
arc welding, dc MMA arc welding, and many other
functions, can satisfy the requirement of all kinds of
welding process. Its widely used in pressure vessels,
construction, shipbuilding, petrochemical industries.
This manual as content has errors, or welding
machine function change, will change this manual at
any time, without prior notice.
Safety Operation
Operator's self protection
• Comply the work safety, sanitation rules, wear rel-
evant work protection equipments to avoid the
damage to eyes and skins.
• In welding time, cover head by the welding face
shield, watch the arc only through the observing
windows on the welding veil.
• Do not let any part of your body touch the two
output poles (Electrode pole and work pole) of
the welders at one time, before you are under the
insulated protection.
• Do not weld in water or high humidity places.
Operator's notices
• TIG 200S PULSE pulse inverter TIG welder is
electric equipment. Its spare parts are fragile. So
do not change or adjust with a rush otherwise the
switch will be damaged.
• Before every welding work, check carefully
whether the welder's correction & earth wire are
correct and reliable.
• Inflammable or explosive materials are prohibited
in the welding areas.
• To ensure the air flow in the welding areas, as the
welding smoke is bad for the health.
• Isolate the arc light to protect others
• Irrelevant persons are not allowed to enter into
the welding area. Forbid to adjust or move the
welders in the welding time.
• Welders have strong electromagnetism and elec-
tric frequency disturbs. Do not let near the per-
sons with heart pacemaker or easily affected by
electromagnetism and electric frequency.
• Do not press, pile or stress the welding wires by
any apparatus. Do not bend the welding wires
into very small angle, otherwise it would hurt the
inside wires to cause the hidden troubles.
