PATON ProMIG DC MMA/TIG/MIG/MAG
- 102 -
The wire feeder is not required in this welding mode.
Procedure for preparing the unit for operation:
- insert the torch cable into the socket of the source B "-" ;
- insert the ground cable into the socket of the source A "+" ;
- connect the grounding cable to the product;
- install the reducing valve on the gas cylinder;
- connect the torch gas hose to the gas cylinder reducing valve;
- open the gas cylinder valve, check for air-tightness;
- connect the mains cable to the power supply;
- put the automatic switch 12 on the rear panel to the ON position;
- use button 4 to set the TIG welding mode (the modes are switched in a circle);
- use buttons 2 to set the current main parameter, this is the welding current;
- if necessary, you can adjust additional functions of the welding process, see paragraph 6.1
for the order of switching.
Caution! The TIG torch must be of valve type, with a Ø13mm bayonet connector.
Choose the maximum torch current according to your operating requirements.
Caution! A common mistake is to sharpen the electrode to a "needle", while the arc
can “wag” from side to side. The correct sharpening is a slightly blunted tip, and the fewer
are the “needle butts” that can withstand the set current, the better. Keep in mind that at
high welding currents, a very sharpened electrode is easily melted due to low heat transfer.
Also,
the “stripes” from sharpening should be located along the axis of the electrode.
