Three-function Welding Machine
Controls and Indicators
1. Gas check function indicator: used to check and adjust the shielding gas flow on the regulator
of the gas reducer before starting the welding process.
2. Welding mode indicator 2T. In 2T mode, pressing the torch control button starts the welding
process, releasing it aborts.
3. 2T / 4T mode switch button
4. 4T welding mode indicator. In 4T mode, welding starts after a short press of the control button
on the torch and stops after a second press. This function allows you not to hold down the but-
ton on the torch when welding long seams.
5. Button for switching the mode of unified (automatic) / partial (manual) adjustment.
6. Mode indicator. Auto / Manual Tuning: The indicator lights up in manual tuning mode. Auto-
matic adjustment means that the welding current and welding voltage are adjusted synchro-
nously (automatically), and manual adjustment means that the welding current and voltage are
set manually (manual adjustment, for professional use)
7. Current regulator
8. Gas pre-purge mode indicator: gas first, then welding. Allows air to be expelled from the torch
and a protective atmosphere is created at the welding site before the arc is ignited.
9. VRD mode indicator: shock protection mode, when the indicator is on, it is in shock protection
mode, and the output voltage is reduced to safe.
10. Gas Purge Mode Indicator Light: Continues gas flow to cool the electrode and ensure proper
crystallization of the sheath weld.
11. Mode switch button. Button for activating / deactivating the VRD function
12. Mode switch button. Shielding gas supply timed before and after welding – to improve the
shielding gas environment
13. CO2 indicator light using 0.8mm welding wire
14. Mode indicator. Turn on the TIG function
15. Mixed gas indicator, using 0.8mm welding wire
16. Regulator. Welding voltage adjustment: (active in manual adjustment mode)
17. Mode indicator. Activating the manual MMA welding function
18. Mode indicator. For cored wire 1.0 mm
19. Mode switch button. Function switching MMA, MIG/MAG, TIG
20. Mode indicator. For 0.8mm flux cored wire
21. Control button. Switching on the wire feed mechanism
22. Voltmeter
