1. Description 1.1. Machine construction The welding machine TT 350MIG/MAG (hereinafter referred to as the source) is constructed as a power frequency converter (inverter). Modern principles and knowledge in the field of semi-conductor technology and controlling electronics have been used when constructing the source. Due to that the source is characterized by: - high power at small dimensions and low weight - high efficiency... -

Provider and operator duties The provider may allow the work with the source only to the persons, who are informed about the safety regulations, trained in the source manipulation and informed about the source operating instructions. The person authorized to work with the source is obligated to follow all basic regulations about safety of operation, with special regard to warnings given in these operating instructions.
- Page 5 safety equipments, health of persons in vicinity, e.g. at the cardiac stimulators use etc. The source must be disconnected from mains by unplugging the fork of the supply cable at any manipulation with the source (change of the standing place, removing of the covers at a regular inspection ).
- Page 6 Using a suitable regulator, ensure that alternate current 10A flows through the created circuit. measure a voltage drop between “the outside protective-conductor terminal” and various parts of the cover where danger voltage may occur. Value of this voltage must not exceed 2.6 V. All found defects must be removed before putting into operation again!! 3.10.

3.11. Placing and installation Due to the stability ensuring it is necessary to place the source on a flat and solid base. Overturning of the source in operation can cause accident of the operator or life hazard. In the area with fire and explosion risk it is necessary to follow the special regulations. - Page 8 5.1.1. Source placing The source must be placed on a solid and flat base to ensure sufficient space for the cooling air supply and outlet in front of the both faces (ca. 500mm). The metal fall-out (e.g. at the grinding) must not be sucked into the machine directly. The welding source is made with the cover IP 21, which means: -protection against penetration of foreign matters with diameter bigger than 12 -protection against vertically dripping water...
- Page 9 This function is not recommended when welding of thin materials. Due to increase of the current, the material can be burnt up. 5.2.2. Use of the remote control If it is necessary to set amount of the welding current directly at the welding workplace, it is possible to connect the remote control “DO1”...

Application of the wire coil and installation of the wire electrode lift off the side plate of the source assemble feeding pulleys for the required diameter of the wire (assembly and change of the pulleys is described in point.5.3.5.) unscrew the plastic backnut of the coil carrier put the coil with the reduction carrier on the driver so that the arresting pin of the driver would lock into the opening of the carrier reduction (keep the correct...
- Page 11 5.3.5. Assembly and change of the feeding pulleys The feeding pulleys must be adjusted to the diameter and composition of the wire used for welding to ensure the optimal feeding of the wire electrode. The pulleys for welding with a steel wire of diameter 0.6 to 1.2 mm are supplied with the source.
- Page 12 5.3.7. After-blow of protective gas This function enables to set a delayed valve switching off after finishing the welding process. The regulation range is 1s-20s. This function is used when it is necessary to protect the weld from oxidation or when cooling the place of the weld finish.
- Page 13 after finishing – press the torch button for longer period (about 1s) and then release 5.3.12. Entering of the welding parameters MIG/MAG into memory This function is good in case that welding of a few same products is repeated. The welding parameters are optimised on the given product and then they are entered into the machine memory.

5.4.2. Welding - press the button “5“ – the segment “A“ of the display “6“ flashes - set the required welding current with the control “8“ - start the protective gas with the control on the torch - start welding by touching W-electrode to the weldment - welding is finished by taking away the electrode from the weldment Note: in this case it is convenient to use the remote control (see Chapter 5.2.2.).
