1. THE TM SERIES
The MIG/MAG welding machine consists of a direct current source (generator),
wire feeder (only for models TM 320W, TM 360W, TM 420W, TM 500W, TM
650W), torch, ground terminal and a cable bundle (only for models TM 320W, TM
360W, TM 420W, TM 500W, TM 650W). Each welding machine has two swit-
ches (16 and 17 in Fig. 1) for adjusting the welding current (models TM 230 e
TM 260 only use switch 16 for this purpose) and two potentiometers (1 and 5 in
Fig. 1) for adjusting the welding duration (timer) and wire speed respectively.
The welding current and wire speed must be adjusted according to the thickness
of the piece to be welded and the wire diameter.
Thicker pieces require a higher welding current and faster wire speed. To obtain
the best results, the speed of the wire must be adjusted each time the thickness
of the material and type of wire to be welded is changed.
IMPORTANT: The welding machine must only be used by qualified and trained
personnel.
All the equipment of the TM series are wire welding machines, produced with an
advanced technique that makes them extremely reliable and sturdy and suitable
for heavy-duty use. Their immediacy in terms of use and ease of learning allows
for quick interchangeability of operators.
