CHAPTER 3. START-UP. ADJUSTMENT AND OPERATION CONTROLS.
In principle, the connection of the system and the preliminary operations must be carried out as indicated
in CHAPTERS 2 and 3 of the GALA INDUSTRIAL power source instructions manual.
A- Wire speed control.
B- Welding voltage control (Electronic power sources).
C- On/Off luminous indicator.
D- Fuse-holder.
General protection system for wire-feed. It contains a 10A DIN 6x32 fuse.
E- Female connector for gun.
F- 2S- 4S working mode switch.
- 2S working mode.
The gun pushbutton must be kept pressed down to carry out the welding operation.
- 4S working mode.
In this mode the finger can be removed from the torch pushbutton when carrying out the welding
operation. To conclude the welding process, the torch pushbutton must be pressed again, releasing it
straightaway.
G- Gas and motor bleed-switch.
With the switch in its end positions we will achieve the exclusive operation of the driving motor or of the gas
passage solenoid valve.
H- Initial acceleration ramp control of driving motor.
The abruptness of the start of the arc can be decreased with this, creating a progression of the motor
speed.
J.- Final wire length control.
It adjusts the final wire length at the outlet from the torch.
I- Hot water connector. (OPTIONAL KIT FOR WIRE-FEED UNITS D-12 A / D-20 A).
For rapid connection of (RED) cooling pipe of gun.
O- Cold-water outlet connector. (OPTIONAL KIT FOR WIRE-FEED UNITS D-12 A / D-20 A).
For rapid connection of (BLUE) cooling pipe of gun.
