6.3 Overheating protection
The welding power source has a thermal overload trip which operates if the
temperature becomes too high, interrupting the welding current and lighting a
yellow indicating lamp on the front of the power source. The thermal overload trip
resets automatically when the temperature has fallen.
7 WELDING
7.1 TIG welding
During TIG welding, the return cable must be connected to (+) and the TIG torch to
(--). If they are connected in reverse, the tungsten electrode will melt.

7.1.1 2--stroke
Gas pre--flow Slope
up Slope down Gas post--flow
Functions when using 2--stroke control of the welding torch.
In the 2--stroke control mode, pressing the trigger switch starts gas pre--flow (if
used) and strikes the arc (1). The current rises to the set value (as controlled by the
slope up function, if in operation). Releasing the trigger switch (2) reduces the
current (or starts slope down if in operation) and extinguishes the arc. Gas
post--flow follows if it is in operation.
7.1.2 4--stroke
Gas pre--flow Slope
up Slope down Gas post--flow
Functions when using 4--stroke control of the welding torch.
In the 4--stroke control mode, pressing the trigger switch starts gas pre--flow (if
used) (1). At the end of the gas pre--flow time, the current rises to the pilot level (a
few ampere), and the arc is struck. Releasing the trigger switch (2) increases the
current to the set value (with slope up, if in use). At the end of welding, the welder
presses the trigger switch again (3), which reduces the current to pilot level again
(with slope down, if in use). Releasing the switch again (4) extinguishes the arc and
starts gas post--flow.
7.1.3 HF
The HF function strikes the arc by means of a spark from the tungsten electrode to
the workpiece as the electrode is brought closer to the workpiece.
