Lincoln Electric SAF-RPO PRESTOMIG 185MP Manual De Instrucciones página 11

The Burnback Time is the amount of time that the weld
output continues after the wire stops feeding. It prevents
the wire from sticking in the puddle and prepares the end
of the wire for the next arc start.
Run-in WFS sets the wire feed speed from the time the
trigger is pulled until an arc is established.
Spot Timer adjusts the time welding will continue even if
the trigger is still pulled. This option has no effect in 4-
Step Trigger Mode.
WARNING
Spot Timer has no effect in 4-Step Trigger Mode.
Preflow Time adjusts the time that shielding gas flows
after the trigger is pulled and prior to feeding.
Postflow Time adjusts the time that shielding gas flows
after the welding output turns off.
Welding GMAW in Synergic Mode (only
PRESTOMIG 210MP)
In synergic mode, the welding load voltage is not set by
user. The correct welding load voltage will set by the
machine's software. This value was recalled on the basis
of data (input data) had been loaded:

The 2-Step - 4-Step changes the function of the gun's
trigger.

2 Step trigger operation turns welding on and off in
direct response to the trigger. Welding process is
performed when the gun's trigger is pulled.

4-Step mode allows to continue welding, when the
gun's trigger is released. To stop welding, the gun's
trigger is pulled again. 4-step mode facilitates to
making long welds.

Spot Timer has no effect in 4-Step Trigger Mode.
Preflow Time adjusts the time that shielding gas flows
after the trigger is pulled and prior to feeding.
Postflow Time adjusts the time that shielding gas flows
after the welding output turns off.
Welding SMAW (MMA) Process
PRESTOMIG 185MP and PRESTOMIG 210MP does
not include the electrode holder with lead necessary for
SMAW welding, but the one can be purchased
separately.
Procedure of begin welding of SMAW process:

First turn the machine off.

Determine the electrode polarity for the electrode to
be used. Consult the electrode data for this
information.

Depending on the polarity of using electrode,
connect the work lead [19] and the electrode holder
with lead to output socket [8] or [9] and lock them.
See the Table 3.


Connect the work lead to the welding piece with the
work clamp.

Install the proper electrode in the electrode holder.

Turn the welding machine on.

Set the welding parameters.

The welding machine is now ready to weld.

By applying the principle of occupational health and
safety at welding, welding can be begun.
