Function and setting
1. Operating in synergic mode
During semi-automatic MIG welding, "operating in
synergic mode" means that with a single control knob
(on the torch), the wire feed and the welding voltage
are adjusted AT THE SAME TIME and synchronized.
All the combinations (wire feed speed & voltage) have
been stored in the microprocessor's memory.
A) Turn the knob ont the torch to increase or decrease
the wire feed and the power according to the thickness
of the metal being welded.
NOTE: It’s better to set a low output at the start and
increase it gradually. This will avoid damaging thework
piece.
B) The wire feed may be fine tuned by using the knob
(- or +) on the front control panel. This fine tuning of
the wire speed is possible regardless of wire size or
type. Once fine tuned, the synergic control on the torch
continues to synchronize the feed and voltage. This
allows the operator to adjust the unit while welding in
any position (e.g. upside down or vertical) without
returning to the panel.
2. Operating in manual mode
In MANUAL welding mode, the control knob on the
torch will control only the welding wire speed while the
knob on the front control panel will be used only to
control the welding voltage. This is means that the
operator will be able to control the welding power and
the welding wire speed separately.
3. Thermal safety
The YELLOW indicator on the front control panel will
light up if the transformer overheats. Once it has
cooled, the indicator light goes off and the transformer
will start up with the same set-up as before the thermal
safety shut it down.
4. Wire drive roller pressure
adjustment
Pressure on the drive roller system is adjusted by
turning the bolt of the upper roller. The pressure
setting is correct when:
A. The wire feeds out smoothly.
B. The rollers slip on the wire if the wire jams or
freezes at the nozzle without the wire "birdnesting"
between the rollers and the wire outlet guide.
5. Sheilding gas flow
The major function of the gas flow during the welding
process, is to protect the melting point from the
contamination. To obtain the optimum of that
protection, there is a delay of one seconde between
the shut off of the welding arc and the end of the gas
flow protection. That over flow will permit an
additionnal protection of the melting point again the
oxydation and a better cooling of the welding tip and
nozzle. That post flow will help us to do stitch welding
under continius gas protection.
