Product Model - Lincoln Electric POWER MIG 215 MPi Operator's Manual

PRODUCT MODEL

The preflow option permits adjusting the time gas flows before
initiation of the arc (0-2 seconds).
The postflow option permits adjusting the time gas flows
after the arc is exstinguished (0-30 seconds).
The gas purge option permits the user to purge air through the
machine for a predetermined amount of time without output
becoming electrically live (10 seconds max).
The 2 Step/4 Step option permits adjusting how the machine
responds to a trigger pull. 2 step will make the machine
start the arc on trigger pull and extinguish the arc on trigger
release. 4 Step will allow the machine to start the arc on the
trigger pull, allow the trigger to be released for longer welds,
and then extinguish the arc on the release of the second
trigger pull.
A. Press and hold the TIG torch trigger to start the sequence. The
machine will open the gas valve to start the flow of shielding gas
according to the set preflow time. After the preflow, the output of
the machine is turned ON. The arc is started with a starting
current of 25 amps. The starting current will be held until the
torch trigger is released.
B. Releasing the trigger starts the initial slope function. This function
increases the output current to the preset operating current in .3
seconds. The operating current is held until the next trigger
interaction.
C. When the main weld is complete, push and hold the torch
trigger to start the final down slope. The machine will
decrease the operating current to the finishing current of
25 amps in .5 seconds.
D. The finished current will be maintained for as long as the
torch trigger is held. Upon releasing the torch trigger,
output will be switched OFF and the set post flow time
will start.
