    MIG/MAG welding of butt and fillet welds. All other uses are prohibited. The automatic welding machines are used in conjunction with ESABÕs control box A2--A6 Process Controller (PEH). The supply voltage to the control box and to the welding machine motors is provided by ESAB’s welding power sources LAF and TAF.

  • Page 9: Welding Method

    Each contact tip has a maximum rated load of 1500 A. MIG/MAG welding For MIG/MAG welding, an A6 Mastertrac A6 TGE1 is used, which has a maximum rated load of 600 A. The welding head is water cooled, with the cooling water supplied by hoses from connections intended for the purpose.

  • Page 10: Equipment

    Equipment Included in a complete welding head are a feed motor (A6 VEC) to feed in the wire and contact equipment which supplies current to the wire and provides a good contact. Contact equipment is available in several different versions. A6 TF is used for submerged--arc welding.

Slide (motor driven). 4. Motor and gearbox (A6 VEC). 5. Flux hopper (1 l). For connection instructions for submerged--arc and MIG/MAG welding, see page 80.

  • Page 12: Installation

    INSTALLATION General The installation must be executed by a professional. WARNING Rotating parts can cause injury, take great care. Connections 3.2.1 General Connection of the control box A2--A6 Process Controller (PEH) to the automatic welding machine is carried out prior to delivery. For further information, see instruction manual for the A2--A6 Process Controller (PEH).
  • Page 13 3.2.3 Gas Metal Arc Welding (MIG/MAG) Connect the control cable (7) between the welding power source (8) and the control box A2--A6 Process Controller (PEH) (2). Connect the return cable (11) between the welding power source (8) and the work piece (9). Connect the welding cable (10) between the welding power source (8) and the automatic welding machine (1).

  • Page 14: Operation

    OPERATION General General safety regulations for the handling of the equipment can be found on page 74. Read through before you start using the equipment! Select wire type and flux powder or shielding gas so that the weld material is as close as possible to the analysis of the base metal.
  • Page 15 MIG/MAG Check that the feed roller (1) and contact jaw or contact tip (3) are of the correct dimension for the selected wire size. Pull the end of the wire through the straightener (2). For a wire diameter greater than 2 mm; straighten out 0.5 m of wire and feed it by hand down through the straightener.
  • Page 16 Changing the feed roller Single wire Release the knobs (3) and (4). Release the hand wheel (2). Change the feed roller (1). They are marked with their respective wire sizes. Twin wire (Twin- -arc) Change the feed roller (1) with twin grooves in the same way as for single wire.
  • Page 17 For single wire 3.0 - - 6.0 mm. Heavy duty (D35) Use the straightener (3), connector (1) D35 with contact jaws (2). Assemble one contact jaw with the M5 bolts provided, in the fixed contact tip (a). Assemble the other contact jaw in the free half of the two--piece connector (b) under the bolt (8) and tighten down hard to ensure that a good contact is achieved between the contact jaws and the wire.
  • Page 18 For twin wires 2 x 1.2 - - 2.0 mm, Light Twin (D35) (Accessories) Use the straightener (3), connector (1) D35 with twin adapter (9) and 2 contact tips (2) (M6 threads) and separate fine wire straightener (4) with two guide tubes (6). For twin wires < 1.6 mm, a guide spiral, inserted into each guide tube, is used.

  • Page 19: Refilling With Flux Powder (Submerged--Arc Welding)

    For single wire < 1.6 mm (D35) Use the straightener (3), connector (1) D35 with contact tip (2) (M12 thread), fine wire straightener (4) with guide tube (6) and guide spiral, which is inserted in the guide tube (6). Assemble the clamp (7) with guide tube (6) in the M12 hole on the standard straightener (3).
