SECTION 7: OPERATION

7.01 Setting welding current and voltage

When the wire had been installed and gas had been set it is possible to start welding.
The appliance must be plugged into the mains, the main switch (Fig. 4, Page 16) in the
"I" position, and the green LED will illuminate.
To select the voltage use step switches (Fig. 4, Page 16).
To select the current (that is linked to the wire speed) use potentiometer encoder (Fig.
7, Page 16).

7.02 Welding modes

The Fabricator torch operator controls work in four modes:
• Continuous two stroke (2T)
• Continuous four stroke (4T)
• Spot welding
• Interval welding

7.03 Secondary parameters

If necessary, it is possible to change the secondary parameters:
Initial wire speed (soft start)
Pre gas time
Post gas time
Burn back time
Time of spots (tack or interval welding)
Time of intervals (interval welding)
Press buttons 3 and 5 at the same time for at least (3s)
On left display will appear ISP. On the right display will appear value of the chosen
parameter.
By means of the Encoder you can change the parameter.
Use the button 3
value of the previous parameter had been stored.
to select the next parameter. When you press the button 3, the
