Adjustment Of Welding Parameters - Elettro 205 STANDARD Bedienungsanleitung

• plug in the cable of heating into the socket (pic. 2, pos. 9) on the machine
and into the connector at the cylinder pressure regulator, polarity is not
important
• press GAS TEST button - for STANDARD on torch, for PROC./SYN. on the
control panel. Turn adjustment screw on the bottom side of pressure val-
ve until flow indicator shows required flow, then release the button
• if the machine was not used for a longer time, or after entire change of
welding torch, it is recommended to blow ways by fresh gas before you
start welding

Adjustment of welding parameters

Adjustment of welding parameters of voltage and speed wire
You shall always allocate speed of wire shift to adjusted voltage (switch po-
sition 1 - 10). Adjusted parameters depend on used protective gas, wire dia-
meter, applied wire type, size and position of a weld etc.
Reference setting of wire speed and switch positions can be found in page
52 - 53.
Machines STANDARD
Adjustment of main welding parameters of welding voltage and speed of
wire shift is carried out with a potentiometer of wire speed (pic. 1A/B, pos.
6) and a voltage switch (pic. 1A/B, pos. 1). You shall always allocate speed of
wire shift to adjusted voltage (switch position 1-10).

Setting speed of wire shift
Press button SET until you switch on LED marked in the picture.
Use the potentiometer to set up required value of shift speed within range
0.5-20 m/min.
NOTE 1: Speed of wire shift can also be adjusted and changed during wel-
ding. Either a potentiometer or a remote control UP/DOWN can be used
during welding (turning the potentiometer).

Adjustment of other welding parameters
Controlling electronics of machines PROCESSOR and SYNERGIC enables ad-
justment of the following welding parameters:
• Time duration of pre-gas (time of protective gas blow before the begi-
nning of welding process).
• Time of start of wire shift speed - function SOFT START (time of start from
minimum shift speed up to value of adjusted welding wire speed, only
PROCESSOR).
• Approaching wire speed (table 4).
• Speed of wire shift m/min (speed of wire shift during welding).
• Time of switching off interval of welding voltage on arc opposite wire
shift: „burning out" of wire towards the torch top.
• Time of post-gas after finishing welding process.
Setting PRE-GAS
Press button SET until you switch on LED marked in the picture.
Use the potentiometer to set up required value of pre-gas time within se-
conds.
Adjustment of wire burning out
Press button SET until you switch on LED marked in the picture.
Use the potentiometer to set up required value of wire burning out within
seconds.
