Welding Data Display; Welding Parameter Setting; Setting The Welding Current (Absolute/Percentage) - EWM Tetrix 451 AC/DC AW FW Operating Instructions Manual

Design and function

Welding data display

•
Insert the end of the hose package through the strain relief of the hose package and lock by turning to
the right.
•
Push the cable plug for the welding current (TIG) onto the connection socket (TIG) and lock by turning
to the right.
•
Insert cable plug on the control lead into the connection socket (28-pole) and secure with crown nut
(the plug can only be inserted into the connection socket in one position).
•
Lock connecting nipples of the cooling water tubes into the corresponding quick connect couplings:
Return line red to quick connect coupling, red (coolant return) and
supply line blue to quick connect coupling, blue (coolant supply).
•
Screw the crown nut on the shielding gas lead gastight to the connecting thread (G¼").
The current lead for preheating (35 mm
such a power source is used.
5.4 Welding data display
The following welding parameters can be displayed before (nominal values), during (actual values) or
after welding (hold values):
Parameter
Welding current
Parameter times
Parameter currents
Material thickness
Welding voltage
JOB number
Program number
When the settings are changed (e.g. welding current) after welding when the hold values are displayed,
the display will be switched to the relevant nominal values.
If the "Program number" signal light is on in addition to the "Material thickness" signal light, the user is in
program mode (programs 1-15, , > see 5.11 chapter).
If the "JOB-number" signal light is on in addition to the "Material thickness" light, the user is in a JOB in
the free memory (JOB 128 to 256, > see 5.10.2 chapter).

Welding parameter setting

During the welding parameter setting process, the parameter value being set is displayed on the left-hand
display. The right-hand display shows the "Factory setting" or a variation of it upwards or downwards.
Displays, e.g. when setting the ignition current, and their meanings:

5.4.2

Setting the welding current (absolute/percentage)

The welding current for the ignition, secondary, end and hot start current can be set as a percentage of
the main current AMP or as an absolute value. To select the display use the parameter
configuration menu <dg _ref_source_inline>Gerätekonfigurationsmenü</dg_ref_source_inline>.
