Page 3: Description
Description New Masterweld inverter MIG welding machines MW2050 / 2070 / 3050 MIG are designed as small and light high performance digital three-phase inverters. New generation digital controls ensure not only optimal setting of the welding characteristics, but its dynamic adaptation during the welding process as well. -

Sparks can cause an ignition many hours after the welding has been finished, especially in unapproach- TTENTION able places. After welding has been finished, let the machine cool down for at least ten minutes. If the machine has not been cooled down, there is a high increase of temperature inside, which can damage power elements.
- Page 6 During welding a wide radiation spectrum is created, out of which the ultraviolet radiation is the most dangerous. Therefore protect your whole body with protective equipment designated for welders. Try to reduce the radiation during welding to a minimum (protective screens, black coating of the welding box, etc.).

While manipulating with the shift, never use protection gloves, there is a danger of catching in the gearing MATERIALS AND DISPOSAL These machines are built with materials that do not contain substances that are toxic or poisonous to the operator. ... -
Page 8: Placement Of The Machine
CONNECTION OF THE MACHINE TO ELECTRICAL SUPPLY The MW2050, MW2070 and MW3050 MIG machines comply with safety class I requirements. This means that all metal parts, which are accessible without the necessity to take off the cover, are connected to protective ground- ing of the electrical supply. -

Always properly secure the gas bottle in a vertical position in a special holder on the wall or in the cart. After you finish welding, do not forget to close the gas tank valve. Picture 2 The following installation instructions apply for most reduction valve types: Step aside and open the gas tank valve (A) for a moment. -

ing of parameters by potentiometer 8 (pic. 5). By pressing SET again or after a few second without any activity the setting mod is leaved. NOTE: Functions and its parameters cannot be changed during welding process. During welding only welding current and speed of wire feed can be changed. - Page 15 Current and speed of feed – change the current and wire feed speed in % in comparison with value adjusted on display. Time – period for which the function is active. The function can be completely turned off by choosing OFF. CRATER FILL This function is used at welding termination.
- Page 16 This function prevents welding wire sticking to melt or the contact tip if properly set. Setting of this function influences the “ball” at the end of the welding wire and subsequently the quality of the next arc ignition. POST GAS TIME This function assures the protective gas presence after welding termination, which prevents the weld end oxida- tion.

The hardness is set by selector 8 (Pic. 5). Confirm the settings by pushing the Dynamics button again or by waiting until the time limit runs out. -
Page 18: Trouble Shooting
Some error messages can be deleted only by turning the machine on and off with the main switch. TROUBLE SHOOTING Display is not on - no voltage is entering the machine. Check the main fuses, replace burned fuses. Check the main supply cable and replace faulty parts. The machine is not welding properly. -
Page 19: Mig/Mag Welding Method
MIG/MAG welding method PRINCIPLE OF MIG/MAG WELDING Welding wire is lead from the roller into the flow drawing tie with the use of the feed. Arc joins thawing wire electrode with welding material. Welding wire functions as a carrier of the arc and as the source of additional material at the same time. -

for welding of thinner sheet metal and welding in forced positions. The switch from the short to the shower arc depends on the welding voltage, the wire diameter and gas mixture (pic. 9). b/ Transient welding arc If the dimensions of the welded material allow it, welding should be done with a higher flashing output (for eco- nomical reasons) without exceeding the long or the shower arc. -

Welding by pushing and pulling A gentle “pushing” move is used during vertical welding in the upward direction and during horizontal welding above the head (pic. 11). Only when welding a descending weld in the downward direction, the torch is held in neutral or slightly “pulling”... - Page 22 Picture 14 SPOT TIME WELDING It is used for welding by individual short spots, whose length can be continuously adjusted. By pressing the switch on the torch, the time circuit is started, which starts the welding process and after the set time it turns off. After further pressing the button, the whole process is repeated.
