work arc start.
The S60.17L, PROGRESS1700L and POTENZA 200 CEL series,
show an improved starting system by Lift Arc. This system allows
a minimum electrode contamination.
To start the TIG welding, the user has to move the commuter 7 to
the TIG position, open the gas output valve and place the torch
tip in contact with the welding piece. Then, wait for 2 seconds and
softly lift the torch for the arc not to automatically start.
Once the arc is started, the user now must proceed to execute
the welding according to its needs. As a general orientation, you
should continue in a conversely way to the electrode welding so
that, instead of pulling it back, the focus will be on pushing forward
as if it was helping the gas flow on the welding coating. Tilt the
torch in order to focus it on a very close vertical position (70º to
80º) with respect to the horizontal and central one, regarding to
the welding coating.
Slowly deposit the filling rod material, successively approaching it
to the fluxed material coating. To end, simply calmly separate the
torch until the arc is interrupted and close the manual gas gate
valve.
Lastly, close the inert gas cylinder general gate valve.
POTENZA TIG 170 HF GE model incorporates two completion
welding adjustment
1. "Down Time" 11 control establishes an intensity drop ramp
when welding is stopped. The ramp starts with the selected work
intensity and ends in zero amperes. Its duration time (from 0
to 5 secs) gets adjusted with the control. The aim is to have a
mild arc stop and a precise control of the cord finalization crater.
As a general rule, the time should be increased as the welding
amperage increases.
2. "Post Time" 12 control establishes the additional gas (argon)
output time (from 0.5 to 7 secs) after finalizing the welding arc.
The aim is to get a non-contaminated weld coating by the air
when it is still liquid or too hot. As a general rule, the time should
be increased as the welding amperage increases.
5.- MAINTENANCE AND SERVICE
INSTRUCTIONS
CLEANING, MAINTENANCE, LUBRICATION
AND SHARPENING
Always turn off the equipment before cleaning and wait for, at
least, 10 minutes for a safe discharge of the power capacitors.
Clean the chassis with a lightly-wet cloth. Depending on the
pollution in the working area air, or at least every 1000 hours,
clean the inside with dry compressed air, removing the casing
and cleaning the dust, metallic pollution and fluffs, always
putting special attention to the fan and the dissipaters.
The equipment does not need a specific maintenance from the
user, but a careful usage in between the environmental limits
that will provide the best guarantee for years of a perfectly safe
service. It is recommendable to send the equipment to the
technical service every 3000 working-hours or every 3 years to
be verified and recalibrated.

User's replaceable pieces list
Due to the complexity and risk potential, it is necessary the
qualified intervention for minor reparations as connection
inspection, standard supply plug replacement and welding
cables revision. Therefore, they are not considered replaceable
pieces by the user but by a qualified person.
