Tig Setup - Jasic EVOLVE 200 Operator's Manual

TIG SETUP

Before starting any welding activity ensure that you have suitable eye protection and
protective clothing. Also take the necessary steps to protect any persons within the welding
area.
TIG welding mode
Terms used: TIG – Tungsten Inert Gas, GTAW – Gas Tungsten Arc Welding.
TIG welding is an arc welding process that uses a non-consumable
tungsten electrode to produce the heat for welding.
The weld area is protected from atmospheric contamination by a
shielding gas (usually an inert gas such as argon or helium) and a filler
rod matching the base material is normally used, though some welds,
known as autogenous welds, are carried out without the
need for filler wire.
The TIG welding process with the Evolve 200
is DC mode only for welding:
•
Mild steel, stainless steel, copper etc.
Connect the TIG torch connector to the "-" quick
socket on the machine panel and tighten it clockwise.
Connect the switch plug on the TIG torch to the corresponding socket on
the machine panel, this is a quick connector so it is not necessary to turn the plug.
Insert the quick plug on the work return cable into the "+" quick socket on the machine front panel and
tighten it clockwise. Firmly fix the ground clamp to the work piece.
Connect the TIG torch gas hose to the quick connector on the machine front.
Connect the gas hose to the gas inlet on the back panel of the machine.
The other end of the supply gas hose connects to the gas regulator on the cylinder.
Please Note:
1. When connecting welding cables, ensure that the machines ON/OFF mains switch is turned off and
never connect the machine to the mains supply with the panels removed.
2. If you want to use long secondary cables (Electrode holder
cable and/or earth cable), you must ensure that the
cross-sectional area of the cable is increased appropriately
in order to reduce the voltage drop due to the cable length.
3. Check these power connections daily to ensure they have
not become loose otherwise arcing may occur when used
underload as shown right.
Switching Machine ON
When the power supply is first turned on after a short period before
welding starts, the fan will initially start and then stop. The fan will then
run automatically when welding begins or if the ambient temperature is
too high.
Please Note:
If the torch trigger is pressed, TIG mode will automatically be selected, if you
then access the Plug & Play and Accessories option in Machine Settings (page 17),
you will note for example 'UNKNOWN TORCH - TIG' will be shown as a fitted accessory.
