Model S60.17L, PROGRESS1700L y POTENZA 200 CEL
GE, has the improved feature of a lift arc starting system
(LiftArc). To initiate the TIG weld, move switch 7 to position
TIG, open the gas outlet valve and bring the tip of the torch
into contact with the piece to be welded. Wait about 2 seconds
and slowly lift the torch so that the arc initiates automatically.
Once the arc has initiated, the weld is made in accordance
with the needs thereof. As a general orientation, it must
advance in a manner inverse to electrode welding so that,
instead of pulling backwards, it is started by pushing forward
as if the gas flow were helped to impact on the weld coating.
Incline the torch such that it is incident in a position near (70º
to 80º) to the vertical line with respect to the horizontal line
and centered with respect to the weld coating.
Slowly deposit the filler material of the rod by bringing the
latter near the coating of successively fused material.
To finish, simply slightly separate the torch until the arc is
interrupted, and close the manual shutoff valve of the inert
gas cylinder.
POTENZA TIG 170 HF GE model includes two welding
adjustments ending:
1. "Down Time" 11 control establishes a decrease amperage
ramp when the welding stops. The ramp starts in the
selected working amperage and it finishes in 0 amps. The
ramp duration (from 0 to 5 seconds) is what it is adjusted with
the control. The purpose is to implement very soft arc stop
for improving finishing and crater quality. As a general rule,
increase the time at the same time you increase the welding
amperage.
2. "Post Time" 12 control established the time (from 0,5 to 7
seconds) of additional gas´s output (argon) after finishing the
welding bow. The aim is that the weld is not polluted by the
air when it is liquid or too hot. As a general rule, increase the
time at the same time you increase the welding amperage.
5.- MAINTENANCE INSTRUCTIONS AND
SERVICE
CLEANING, MAINTENANCE, LUBRICATION,
SHARPENING
For cleaning operations, always disconnect the equipment
and wait for at least 10 minutes for securing that capacitors
are discharged. Clean the housing with a slightly wetted
cloth.
Depending on the pollution of the working environment or at
least every 1000 hours, clean the inside with dry compressed
air, removing the upper housing and eliminating dust, metal
pollution and fluffs, paying special attention to dissipaters
and to the fan.

List of parts that may be replaced by the user.
Due to the sophistication and potential danger, qualified
intervention is required except for minor repairs such as
inspection of connections and replacement of the standard
power supply plug and revision of the welding cable; they
are therefore not considered as parts that are replaceable
by the user.
