START‐UP ATTENTION: Before start‐up, read the chapter "Safety rules", paragraph 15. 2.1 INTENDED USE The welding machine is designed solely for manual metal arc welding with a stick electrode, tungsten arc inert gas welding, as well as semiautomatic metal inert/active gas welding. PATON PRO-series DC MMA/TIG/MIG/MAG ‐ 5 ‐ ...
ATTENTION: The machine may be life‐threatening after a hard fall. So place it on stable solid surface. 2.3 POWER CONNECTION The welding machine of series design is rated for mains voltage of 220 V (‐27% +18%) or three‐phase mains voltage of 3х400 V (±20%). ATTENTION: All manufacturer's warranty liabilities become void if the machine is connected to mains voltage exceeding 270 V! Such a situation may occur due to large imbalance of line‐to‐line voltage in standard mains or due to use of non‐standard connection. In addition, manufacturer's warranty liabilities become void if mains line has been connected by mistake to the neutral wire or to the source earthing wire during connection of a three‐phase machine. Mains connector, cross‐sections of power supply cables and supply‐line fuses must be selected on the basis of technical specifications of the machine. PATON PRO-series DC MMA/TIG/MIG/MAG ‐ 6 ‐...
ATTENTION: Mains switch 9 is a signal button, which only isolates power current of the welding machine, but does not provide complete de‐energization of internal electronic parts of the machine. Therefore, in accordance with safety rules, remember to remove the plug from the socket when reconnecting the machine. 3. MANUAL METAL ARC WELDING (MMA WELDING) Procedure for machine preparation to operation: ‐ insert the electrode cable into the source socket А "+"; ‐ insert the "earth" cable into the source socket B "–"; ‐ connect the "earth" cable to the work piece; ‐ connect the mains plug to the supply mains; ‐ set the power switch 9 on the rear panel to position "I"; ‐ set the MMA welding mode by pressing the button 7 – the modes switch over end‐around; ‐ use buttons 3 to set the main parameter, which is arc current; ‐ if necessary, additional functions of welding process can be adjusted – see changeover sequence in paragraph 6.1. ATTENTION: Once the power switch is set to position "I" in the MMA welding mode, the stick electrode becomes energized. Do not touch conductive or earthed objects, such as, for example, welding machine frame etc., with the electrode, since the machine will take this as a signal to start the welding process.

(if the machine is operated from good power mains). However, keep in mind that boosted current of this function can burn through the work piece when welding thin metal pieces, so it is recommended to reduce the Hot Start value in such a case. The result is achieved by the following means: In the moment of arc striking, arc current increases by the default value of +40% for a short time. Example: welding with a Ф3 mm electrode, set base value of arc current is 90 A. Result: hot start current is 90 A + 40% = 126 A. In the additional settings, you can change both Hot Start magnitude [H.St] and Hot Start time [t.HS]. Do not set Hot Start magnitude and time to unnecessarily high values, since large limit values required for very strong power supply mains, and if good mains is not available, striking process can even abort. See paragraph 6.1 for sequence of changing the value of any function in the current welding mode. PATON PRO-series DC MMA/TIG/MIG/MAG ‐ 8 ‐...
The result is achieved by the following means: Due to reduction of arc voltage below the minimum permissible voltage of stable arc burning, arc current increases by the default value of +40%. In the additional settings you can change both Arc Force magnitude [Ar.F] and trigger level of this function [u.AF]. Do not set Arc Force magnitude and trigger level to unnecessarily high value, because at high limit values, especially during welding with thin electrodes less than Ф3.2 mm in diameter, affects actuation of Anti‐Stick function, which will be explained in the next paragraph. See paragraph 6.1 for sequence of changing the value of any function in the current welding mode. PATON PRO-series DC MMA/TIG/MIG/MAG ‐ 9 ‐ ...
In 0.1 s after the electrode is detached from the work piece, voltage on the source terminals drops to safe level below 12 V. To enable this function, an open‐circuit voltage reduction unit [BSn] is required. This unit is envisaged in this equipment model, but is set to "OFF" position by default, i.e. disabled, since it is known, that enabling of any function of this kind PATON PRO-series DC MMA/TIG/MIG/MAG ‐ 10 ‐...
60 A, but stability of the welding process and dilution in the welding pool will change. This is a very important condition for the user when he/she needs to estimate the exact change of heat input into the weld pool, for example, when he/she compares this current with another base current without the pulsed welding mode.

EXCLUDE usage of combustible gases! Other gases can only be used upon approval of the equipment manufacturer. Procedure for machine preparation to operation: ‐ insert the torch cable into the source socket B "‐"; ‐ insert the "earth" cable into the source socket A "+"; ‐ connect the "earth" cable to the work piece; ‐ install pressure reducer on the gas bottle; ‐ connect gas hose of the torch to pressure reducer of the gas bottle; ‐ open the cock of the gas bottle and check it for tightness; ‐ connect the mains plug to the supply mains; ‐ set power switch 9 on the rear panel to position "I"; ‐ set the MMA welding mode by pressing the button 7 – the modes switch over end‐around; ‐ use buttons 3 to set the main parameter, which is arc current; ‐ if necessary, additional functions of welding process can be adjusted – see changeover sequence in paragraph 6.1. ATTENTION: Argon torch shall be a valve torch, with a bayonet connector of Ф9 mm (PRO‐160) or Ф13 mm (PRO‐200/250). Select maximum torch current depending on your operating requirements. ATTENTION: A common mistake is "needle‐like" electrode sharpening; in this case, arc may wag from side to side. A correctly sharpened electrode has slightly blunted PATON PRO-series DC MMA/TIG/MIG/MAG ‐ 12 ‐...
You shall get used to the optimum electrode detachment speed. Time of current fade‐in [t.uP] up to the set value will be reviewed in the next paragraph. 4.3 ARC CURRENT FADE‐IN FUNCTION Except for saving operating life of the electrode and, to some extent, of the torch itself, this function is also requires for convenient use of the torch. It eliminates initial splashing of weld pool. In addition, one can guide the torch exactly to the PATON PRO-series DC MMA/TIG/MIG/MAG ‐ 13 ‐ ...

Accordingly, heat input into the weld will remain at the level of 100 A, but stability of the welding process and dilution in the welding pool will PATON PRO-series DC MMA/TIG/MIG/MAG ‐ 14 ‐...
"Ar" and sometimes expensive helium "He". For stainless and high‐alloy steels, mixtures with different ratios are often used, such as "80%Ar+20%CO2". Other gases can only be used upon approval of the equipment manufacturer. Procedure for preparation to welding with solid wire: ‐ insert the "earth" cable into the source socket B "‐"; ‐ connect the "earth" cable to the work piece; ‐ connect one end the premanufactured power jumper with cable cross‐section of at least 16 mm to the source socket А "+", and the other end to power terminal of the wire‐feeding machine, which is case‐specific, so there is no point in listing all possible options; ‐ connect the semiautomatic welding torch to the wire‐feeding machine; PATON PRO-series DC MMA/TIG/MIG/MAG ‐ 15 ‐ ...

‐ if necessary, additional functions of welding process can be adjusted – see changeover sequence in paragraph 6.1. Control slot 8 on the rear panel provides control over switching the source on and off. Connection diagram: Contacts 1 and 2 are the only used contacts, which are closed at the required time. When the source must operate, close the contacts, and when it must be switched off, open them. ATTENTION: Connection diagram and its configuration in wire‐feeding units is individual for each particular case, so it is not provided in this operation manual for the source. You can find it in the operation manual of the feeding unit. The new‐generation independent wire‐feeding units produced by PATON have everything prearranged, so they can be adapted with a minimum of effort. The only thing that takes some time is securing the plug in the socket 8. Remember to supply shielding gas. If you are new to welding and do not have experience in establishing optimum pressure for welding of a specific work piece, you can for the first time set gas pressure above the optimum value ~0.2 MPa: this will have minor effect on the process, only increase consumption of shielding gas. However, follow general recommendations on semiautomatic welding in the future PATON PRO-series DC MMA/TIG/MIG/MAG ‐ 16 ‐...
Remember that these parameters are different for each specific application. 5.1 WELDING CYCLE – MIG/MAG t, s t, s t, s See paragraph 6.1 for sequence of changing parameters of functions. Time of pre‐purging ( ) and post‐purging ( ) with shielding gas is set on the wire‐feeding machine. 5.2 FUNCTION OF VOLTAGE FADE‐OUT IN THE END OF WELDING This function is designed for smooth filling of a crater, which is formed in the weld pool by the action of electromagnetic draft of the electric arc and subsequently becomes a source of weld defects. Release of the torch button in the end of welding becomes the signal to start the function. Once this happens, stop moving the torch and weld the pothole (which is a crater) in the weld with fading‐out voltage. Smoothness of this process can be controlled through voltage fade‐out time [t.dn] both in the source and in the wire feeding speed control unit. These values must be PATON PRO-series DC MMA/TIG/MIG/MAG ‐ 17 ‐ ...
18 V, and pulsing power [Po.P] = 20%, while pulsing frequency [Fr.P] = 20 Hz and duty ratio [dut] = 50% by default. Result: current will pulse in the range from 14.4 V A to 21.6 V with frequency of 20 Hz, pulses will be of the same shape in terms of both magnitude and time. The duty ratio parameter is set to 50% by default. If this parameter is changed to a value other than 50%, voltage pulse time and voltage pause time become asymmetric: by default duty ratio [dut] = 50% duty ratio [dut] = 20% duty ratio [dut] = 70% t, s t, s t, s In this case, the machine will calculate the mode in such a way, that average voltage level of the welding process will be at the level of the set base arc voltage of 18 V (as it was set). Accordingly, heat input into the weld will remain at the level of 18 V, but stability of the welding process and dilution in the welding pool will change. This is a very important condition for the user when he/she needs to estimate the PATON PRO-series DC MMA/TIG/MIG/MAG ‐ 18 ‐...
After the button is released, the display shows current value of this function, which can be increased or decreased with buttons 3. By quickly pressing and releasing button 5, one can switch to the next function end‐around. ATTENTION: If button 5 is being held for a long time while the user views the function name, then in about 10 s the digital board will display countdown 333…222…111 warning about reset of all settings of the current mode. This option will be considered in the paragraph below. PATON PRO-series DC MMA/TIG/MIG/MAG ‐ 19 ‐ ...
