«MANUAL» MODE
To set your device, proceed as follow:
- Choose the welding voltage using the 10 positions switch
- Adjust the wire speed with the potentiometer
.
Advice
The wire speed adjustment is often determinated « with the noise »: the arc must be stable and have a
low crackling.
If the speed is too low, the arc is not continuous.
If the speed is too high, the arc crackles and the wire pushes back the torch.
« SYNERGIC » MODE
This function will set the wire speed automatically.
For this:
Position the wire speed potentiometer
in the middle of the« Optimal synergic » zone.
-
Select:
The wire type
The wire diameter
The power mode (10 position switch), to select the right position in accordance with the thickness
of the part to weld, please refer to the table ⑧
From this combination, the Trimig 255-4 determines the optimal wire speed and the device is ready to weld.
It is also possible to adjust the wire speed if necessary by adjusting potentiometer
+ or – manually.
A memory of the last welding configuration is done (wire diameter, wire type, mode).
GAS choice (only for steel welding) :
In synergic mode, the trimig 255-4S determines the welding settings in accordance with the gas used. By
default, in steel welding the machine is set in « Argon + CO2 ».
To change the gas and set the machine in C02 mode or come back in Argon + CO2 mode, process as
explained:
1-
Press « Type » for 5 seconds until the keyboard switches off the release.
2-
Within 5 seconds, choose the required setting with the key « choose mode ».
Normal (2T) =>
Argon + CO2 (default setting)
Delay
=>
CO2 100%
3-
The confirmation is done either by the « Type » key, or by waiting for 5 seconds.
4-
Once confirmed, the machine reverts to the normal functioning mode but the modification is
registered even when the machines is switched off.
SPOT MODE
This function allows spot welding.
To adjust the length of each spot, use the potentiometer
.
DELAY MODE
Allows intermittent welding, the delay can be adjusted through the potentiometer
.
This function allows welding very thin steel or aluminium metal sheet, limiting the risk of piercing and
distortion (especially for aluminium welding).
