IP21S: Case protection degree. IP means Interna-
tional Protection. 2 means to prevent peo-
ple use their fingers to reach the danger-
ous parts; Prevent solid eyewinker, diameter
less than 12.5mm, to enter into the case; 1
means to prevent upright drip; Upright drip
should have no bad influence. S means that
the water protection test was made when the
moving parts (such as the rotor of the rotary
motor) was stopped.
F: Class F Insulation Degree
Functions
Manual metal-arc welding
This mode is equivalent to the function of the dc arc
welding machine, the manual welding electrode
welding function.
Argon arc welding
Widely used in a variety of carbon steel, alloy steel,
stainless steel, copper and copper alloys, nickel and
nickel alloy welding, especially suitable for thin plate
welding (3 mm or less) and plate (> 3 mm) in the
opening of one side welding groove butt weld, dou-
ble-sided molding, backing welding process, espe-
cially suitable for argon arc welding backing, dc
manual arc welding more than cover the welding
process.
DC pulse argon arc welding
Panel Settings "hand arc/argon arc" the argon arc
position, "steps 2/4" set "step 2" position. Panel Set-
tings "hand arc/argon arc" the argon arc position,
"steps 2/4" set "step 2" position.
Is suitable for thin plate welding, and is suitable for
any position of continuous welding, do not need to
adjust the welding specification for welding position
change. In addition to get the big melt in both deep,
and expect to reduce the welding heat affected
zone, pulse welding current, base value current,
pulse width of the reasonable choice will be good
to meet specific needs. Pulse welding current is to
strengthen the mixing of molten pool, to minimize the
pores. Under the same line energy, dc pulse arc than
dc constant current arc penetration is big, pulse
current of coagulation, form and normal form is dif-
ferent, it can improve the mechanical properties of a
particular joint. Properly adjusting the parameters of
the pulse and the welding speed, smooth dc pulse
argon arc welding can form uniform and controllable
fusion zone (scales).
Pulse frequency (TIG 200S PULSE series)
Pulse: Is in a state of current (dc), to the current surge
in the form of a pattern. The current supply in pulse
way, set up the welding current and base current, set
the pulse frequency and pulse width parameter.
"2step/4step" option
Under argon arc welding method, the "steps" 2/4
"" set in step [4], press the torch switch, arc is estab-
lished and began to burn, the arc work in" striking
current ", At this time you can put away the torch
switch, electric arc by the striking current phase
shifted to the current slow rise stage, after the current
slow appreciation set current into the welding current
stage; Again press the gun switch, electric arc by the
welding current into the "current slow down" phase,
when the current drop to crater arc current stage in
"crater arc current, the loosen rob switch, arc extin-
guishing, welding process is over. Without this fea-
ture when 2 step.
Current Adjustment Instruction
Welding current
Arc welding current refers to the "hand/argon arc"
function mode Settings of the welding current size,
at the same time refers to the pulse argon arc weld-
ing of pulse peak electric current. At this time of the
arc heat is big, the workpiece heated, it is used to
welding.
Base Current
Base current means the minimum current in the pulse
current welding. In the base current time, the arc has
the smallest quantity of heat, so the work piece has
the ability to transfer away the quantity of heat in the
melted bath, got in the peak time.
Pulse frequency
Pulse frequency refers to the pulse argon arc welding
state, the current adjust speed rate between welding
current and base value current.
Duty ratio
Duty ratio is welding peak current's ratio during one
cycle time under pulse argon arc welding condition.
Duty ratio in the range of 15-85% is adjustable.
Such as: the frequency of 5 hz (its pulse cycle is 200
ms) of pulse current in each cycle of welding current
peak time is 80 ms, so, the duty ratio of pulse are as
follows: 80÷200×100% = 40%.
The current slow rise time
Current slow rise time refers to the time of from
