2) This machine is not a professional high-frequency arc starting argon arc welding machine, it is only a LIFT TIG
contact arc starting or friction starting.
3) Need to use TIG, wp17v torch, this torch is not included, you need to buy it yourself
4) Support welding material material, carbon steel, stainless steel, alloy steel, aluminum can not be welded.
5) This welding mode requires the use of tungsten needles, which need to be purchased separately, and the size
of the tungsten needle must match the collet and collet body of the welding gun, otherwise it cannot be
installed
6) In this mode, argon welding must be used.
possible problems
1) There is no response when starting up, please check the plug connection.
2) There is no response when booting up, please open the cover and check whether the internal connection
wires are loose.
3) During the welding process, if the time exceeds 3 minutes, over-current protection may occur. You need to
stop working for a few minutes, let the machine cool for a period of time, and automatically recover. If the air
cools for more than 10 minutes, the machine does not automatically recover, please shut down and restart.
4) If you have any questions, please contact us at service@mirthtek.com.
5)Lift tig is different from professional high-frequency tig. Lift tig needs to be welded after contact with arcing.
High-frequency tig does not require contact with arcing. Lift tig is not suitable for spot welding.
Part 6: Internal diagram of the machine
1. 8 imported transistors, stable and powerful current output.
2. 4 high-power large capacitors, the machine is more stable.
3. Two cooling fans, greatly improving the machine load duration.
4. The main transformer of all copper is 18:3, the size of the magnetic core is: 56×28×28, the
power is larger.
5. In addition, an output reactance is added, the output welding current is more stable, the
