&Brief Introduction

TIG 200E AC/DC PULSE welding machine adopts the latest pulse width modulation (PWM) technology and insulated gate bipolar transistor (IGBT) power module, which can change work frequency to medium frequency so as to replace the traditional hulking work frequency transformer with the cabinet medium frequency transformer. Thus, it is characterized with portable, small size, light weight, low consumption and etc.
The parameters of TIG 200E AC/DC PULSE on the front panel all can be adjusted continuously and steplessly, such as start current, crater arc current, welding current, base current, duty ratio, upslope time, downslope time, pre-gas, post-gas, pulse frequency, AC frequency, balance, hot start, arc force and arc length etc. When welding, it takes high frequency and high voltage for arc igniting to ensure the success ratio of igniting arc.

TIG 200E AC/DC PULSE Characteristics:
>MCU control system, responds immediately to any changes.
>High frequency and high voltage for arc igniting to ensure the success ratio of igniting arc, the reverse polarity ignition ensures good ignition behavior in TIG-AC welding.
>Avoid AC arc-break with special means, even if arc-break occurs the HF will keep the arc stable.
>Pedal control the welding current.
>TIG/DC operation, If the tungesten electrode touches the workpiece when welding, the current will drop to short-circuit current to protect tungsten.
>Intelligent protection: over-voltage, over-current, over-heat, when the problems listed before occurred, the alarm lamp on the front panel will be on and the output current will be cut off. It can self-protect and prolong the using life.
> Double purposes: AC inverter TIG/MMA and DC inverter TIG/MMA, excellent performance on Al-alloy, carbon steel, stainless steel, titanium.
According to choosing the front panel functions, the following six welding ways can be realized.

DC Pulse TIG
AC Pulse TIG


&Module Explanation

The module explanation of arc welding machine must accord with the correlativeprescripts of National Standard GB10249. It is explained as the following.


&Optional shells


&Polarity Connection (MMA)
MMA (DC): Choosing the connection of DCEN or DCEP according to the different
electrodes. Please refer to the electrode manual.
MMA (AC): No requirements for polarity connection


&Assembling the equipment (TIG)
♦ Workpiece is connected to the positive electrode of welding machine, and welding
torch is connected to the negative electrode, which is called DC POSITIVE
CONNECTION; otherwise, that is called DC NEGATIVE CONNECTION. Generally, it
is usually operated in DC POSITIVE CONNECTION in TIG welding mode.
 The control cable of torch switch consists of 2 wires, pedal control of 3 wires and the
aero socket has 14 leads.
Consumable parts for TIG torch, such as tungsten electrode, tip, gas nozzle,
electrode shield(short/long), please enquire us by mail or phone according to the
accessory codes.
When TIG 200E AC/DC PULSE welding machines are operated in HF ignition
method, the ignition spark can cause interferences in equipment near the welding
machine. Be sure to take specially safety precautions or shielding measures.


&Layout for the panel


1 Aero socket: Is connected to torch switch control wire. (It has 14 leads and lead  - lead 9 are connected to torch switch control wire)
2 Negative output: The welder’s negative polarity output.
3 Shield gas connector: Is connected to the gas input pipe of torch.
4 Positive output: The welder’s positive polarity output.
5 Power source switch: Switch to “ON”, the welder is turned on, while switch to
“OFF”, the welder is turned off.
6 Power source input: To connect power source.
7 Shield gas input joint: To connect one head of the gas hose while the other head of which is connected to argon gas cylinder.
8 Fan: Take away heat to heat the machine.

&Control panel




&Pedal switch control
When plug the fourteen-lead aero-socket of pedal switch in it. Welder will identify the
pedal switch, the welding current knob on the front panel will can’t use, and only 2T can
be selected.
 When use the adjustment knob of max-welding current beside the pedal ,can set the
max-current you want.
 The eighth and ninth of the fourteen-lead aero-socket is gun switch; The first and
second of the fourteen-lead aero-socket is short circuit; The third, fourth and fifth of the
fourteen-lead aero-socket is pedal adjustable resistance.


&Gun switch control current


&TIG welding (4T operation)
The start current and crater current can be pre-set. This function can compensate the
possible crater that appears at the beginning and end of the welding. Thus, 4T is suitable
for the welding of medium thickness plates

♦ 0: Press and hold the gun switch, Electromagnetic gas valve is turned on. The
shielding gas stars to flow;
♦ 0~t1: Pre-gas time (0~2S);
♦ t1~t2: Arc is ignited at t1 and then output the setting value of start current;
♦ t2: Loosen the gun switch, the output current slopes up from the start current;
♦ t2~t3: The output current rises to the setting value (Iw or Ib), the upslope time can
be adjusted;
♦ t3~t4: Welding process. During this period, the gun switch is loosen;
Note: Select the pulsed output, the base current and welding current will be outputted
alternately; otherwise, output the setting value of welding current;
♦ t4: Press the torch switch again, the welding current will drop in accordance with the
selected down-slope time.
♦ t4~ t5: The output current slopes down to the crater current. The downslope time
can be adjusted;
♦ t5~t6: The crater current time;
♦ t6: Loosen the gun switch, stop arc and keep on argon flowing;
♦ t6~t7: Post-gas time can be set by the post-gas time adjustment knob on the front
panel (0~10S);
♦ t7: Electromagnetic valve is closed and stop argon flowing. Welding is finished.

&TIG welding (2T operation)
This function without the adjustment of start current and crater current is suitable for the
Re-tack welding, transient welding, thin plate welding and so on.

♦ 0: Press the gun switch and hold it. Electromagnetic gas valve is turned on. The
shielding gas stars to flow.
♦ 0~t1: Pre-gas time (0~2s).
♦ t1~t2: Arc is ignited and the output current rises to the setting welding current (Iw or
Ib) from the min welding current.
♦ t2 ~ t3: During the whole welding process, the gun switch is pressed and held
without releasing.
Note: Select the pulsed output, the base current and welding current will be outputted
alternately; otherwise, output the setting value of welding current;
♦ t3: Release the gun switch, the welding current will drop in accordance with the
selected down-slope time.
♦ t3~t4: The current drops to the minimum welding current from the setting current (Iw
or Ib), and then arc is turned off.
♦ t4~ t5: Post-gas time, after the arc is turned off. You can adjust it (0~10s) through
turnning the knob on the front panel.
♦ t5: electromagnetic gas valve turned off, the shield gas stops to flow, and welding is
