CONSTRUC TION AND USE

The welding machine is a device with insulation class I and it 
is used for MMA welding. MMA welding uses coated electrodes 
installed in MMA welding cable clamp. These electrodes are 
melted with the welded material. Welders have constant current 
characteristics.

Before connecting the tool to mains network make sure that 
the supply voltage and current are matched with values shown 
on the rating plate. Power cord must be protected with fuses 
or circuit breakers, their operating range must be appropriate 
for the tool operating power. Connect the welding machine to 
power supply and make sure the control indicator is on. 

CAUTION: Electric system should be equipped with residual 
current circuit breaker appropriate for the rated current of 
the welding machine. The system should be professionally 
set and provide correct functioning at the rated load of the 
residual current circuit breaker.

OPERATION / SET TINGS

CAUTION: Always connect the welding machine to power 
supply in the end, after preparing the material and making 
sure that all the connections are done correctly.

MMA WELDING

To star t MMA welding:

•

Connect the ear th cable (

B

) to the socket (

1

).

•

Connect the MMA welding cable (

A

) to the socket (

2

). 

•

Only when the device is correctly connected you can connect 
power supply and turn the device on with the switch located 
on the rear wall of the device. 

•

Use the welding current setting knob (

12

) to set required 

welding current, depending on welding electrode used and 
thickness of processed piece. 

INDICATION

The device features two indicating diodes (4, 5). Device power 
indicator diode (4) shows when the device is connected to 
electric power supply. Winding overheat indicator diode (5) turns 
on when the device works too long at high load and the winding 
temperature exceeds allowed value. When the diode (5) turns 
on, stop operation immediately. Wait until winding temperature 
drops down and the diode (5) turns off. Only when the diode 
(5) turns off it is possible to continue device operation. When 
the indicator diode (5) turns on immediately after connecting to 
power supply, then the power supply voltage is different from 
the rated voltage. In such case disconnect the device and check 
the power supply. 

CAUTION: 

When you exceed rated operation time when 

welding, the device temperature increases above allowed value. 
This may cause damage and/or faster wear of the device. 

IMPORTANT: 

Provide good connection between welded object 

and the welder clamp. Use the dial to set current intensity 
adequate for material thickness and type of the weld. High 
intensity of welding current may inter fere with operation of 
other electrical devices.

Duty cycle X(%) 

defines rated load time related to 10 minute 

working cycle at a given load. For example, marking of 60% 
means 6 minutes of operation at a given load (specified in the 
table along with rated data and in the table on the device), and 4 
minutes rest before star ting the device again. 

OPERATION AND MAINTENANCE

CAUTION! Unplug the power cord from mains socket before 
commencing any activities related to installation, adjustment, 
repair or maintenance.
