MIG S 

(3-phase)

 + SWF 2

1. Introduction

In case of MIG/MAG welding method the arc is generated between the automatically fed 

welding wire

 and the 

working piece

, shielding in CO

2

 gas or gas mixture.

The machine is able to weld unalloyed  and low alloyed  

steel plates

. When welding thin car  chassis, the 

application of 

gas mixture

 is recommended, whilst in other cases, when deep penetration is required, 

pure CO

renders better solution.

Important  advantages   of  this  technology  are  high  

heat   concentration

  and  

current  density

  so  warp  of  the 

material is very low.

Additional advantages:

 high welding speed, quick melting,

 wide range of welding parameters,

 deep penetration, high melting rate,

 easy automation,

 ability to weld of thin plates, roots, etc.,

 no slag on the welded seam.

The   equipment   consists   of  two,  

separated

  units:   the  

Power   Source

  and   the  

Wire   Feeder

,  and   they  are 

connected with cables and hoses of 10 m long. The 

power source

 is designed to constitute a compact unit with 

the 

gas bottle

 and the 

undercarriage

 fixed to it.

Main parts of these units:

 Metal housing with wheels and fan

 Metal housing with central torch adaptor

 Main transformer (of flat static characteristic)

 Wire feeding unit with motor

 Rectifier bridge

 Solenoid (gas) valve

 Choke for smoothing the current

 Electronic control unit

 Auxiliary transformer and contactor

 Connecting cables and hoses (10 m)

3. Transport and storage

The   manufacturer   delivers   the   equipment   with   standard  

accessories

  and  

undercarriage

  mounted.   Before 

transport, the machine has to be secured against tipping over and protected against adverse effects of the weather.

It must be stored at dry, covered places.
It shall be loaded and unloaded by 

lift trucks

.

Protect it against moisture and mechanical shock carefully!
