Operating manual
• Fan performance: in MMA welding mode, the fan will work continuously. In TIG mode, the fan will only operate during the welding phase, then it will
stop after cooling.
• Warning: Increasing the length of the torch or return cables beyond the maximum length indicated by the manufacturer will increase the risk of
electric shocks.
• The arc-starting and stabilising features are designed for both manual and mechanically guided operations.
CONNECTING TO THE POWER SOURCE
These welding machines can be used with a battery-based power source provided that the auxiliary power meets the following requirements:
- The voltage must be alternating, set as stipulated and with a peak voltage of less than 700 V for the TIG 300 DC and 400 V for the PROTIG 221 DC FV.
- The frequency must be between 50 - 60 Hz.
It is imperative to check these conditions as many battery-based power sources produce high voltage spikes that can damage the welding unit.
USING EXTENSION LEADS
All extension leads should be the correct size and diameter for the equipment's voltage requirements. Use an extension lead that complies with na-
tional regulations.

GAS SUPPLY
This equipment is equipped with two connection points. A gas cylinder connection point to allow shielding gas to enter the machine and a gas torch
connection point allowing gas to escape through the end of the torch. In order to guarantee ideal connections, we recommend that you use the adap-
tors that come supplied with the machine.
REBOOTING THE WELDING MACHINE
It is possible to restore the welding unit's factory settings. You can access this advanced setting by pressing the 'JOB' button for longer than three
seconds. You must then select 'Ini'. The screen will then display the numbers '3', '2' and '1' before rebooting the device.

Comments
TIG welding with HF ignition
TIG welding with Lift-Arc ignition
Time taken to purge the torch and create a gas shield before
ignition.
Rising current ramp
Second welding current
In 4TLOG or pulsed-welding mode, the second current is called
the 'cold' welding current
The PULSED mode's pulse frequency (Hz)
Descent ramp to avoid crater cracks (S)
The amount of time the gas shielding is sustained after the arc
is extinguished. It protects the part and the electrode against
oxidation (S)
The overcurrent is fully adjustable at the start of the welding
process (%)
An overcurrent is delivered during the welding process to prevent
the electrode from sticking to the weld pool
