OPERATION FABRICATOR 211i CAUTION Loose welding terminal connections can cause overheating and result in the male plug being fused in the bayonet terminal. 8. Negative Welding Output Terminal The negative welding terminal is used to connect the welding output of the power source to the appropriate welding accessory such as the MIG gun (via the MIG polarity lead), TIG torch or work lead.
Page 28
FABRICATOR 211i OPERATION 10. Multifunction Control - Voltage, Down Slope & Arc Force The multifunction control knob is used to adjust Voltage (MIG Mode), Down slope (LIFT TIG Mode) and Arc Force (STICK Mode) depending on the welding mode selected.
Page 29
OPERATION FABRICATOR 211i 4T Latch Mode This mode of welding is mainly used for long welding runs to reduce operator fatigue. In this mode the opera- tor can press and release the torch trigger and the output will remain active. To deactivate the power source, the trigger switch must again be depressed and realised, thus eliminating the need for the operator to hold the torch trigger.
Page 30
FABRICATOR 211i OPERATION 16. On / Off Switch This Single Phase circuit breaker performs a dual function. It is used to turn the unit on/off and it will also trip in the event of a fault. WARNING When the front digital displays are lit, the machine is connected to the Mains supply voltage and the internal electrical components are at Mains voltage potential.
21. Cooling Fan The Fabricator 211i is fitted with a fan as needed feature. Fan as needed automatically switches the cooling fan off when it is not required. This has two main advantages; (1) to minimize power consumption, and (2) to minimise the amount of contaminants such as dust that are drawn into the power source.
FABRICATOR 211i OPERATION 4.03 Installing 15kg Spool (300mm diameter) As delivered from the factory, the unit is fitted with a Wire Spool Hub which accepts a Spool of 300mm diameter. Remove the locking pin from the spool hub. Install the wire spool over the spool hub, locating the hole in the spool, with the alignment pin on the spool hub.Insert the locking pin back into the spool hub.
OPERATION FABRICATOR 211i 4.05 Inserting Wire into the Wire Feed Mechanism Release the tension from the pressure roller by turning the adjustable wire drive tension screw in an anti-clockwise direction. Then to release the pressure roller arm push the tension screw toward the front of the machine which releases the pressure roller arm (Figure 4-8).
FABRICATOR 211i OPERATION 4.06 Feed Roller Pressure Adjustment The pressure (top) roller applies pressure to the grooved feed roller via an adjustable pressure screw. These devices should be adjusted to a minimum pressure that will provide satisfactory WIREFEED without slippage. If slipping occurs, and inspection of the wire contact tip reveals no wear, distortion or burn back jam, the conduit liner should be checked for kinks and clogging by metal flakes and swarf.
OPERATION FABRICATOR 211i 4.08 Wire Reel Brake The wire reel hub incorporates a friction brake which is adjusted during manufacture for optimum braking. If it is considered necessary, adjustment can be made by turning the Thumb Screw inside the open end of the hub clockwise to tighten the brake.
Page 36
FABRICATOR 211i OPERATION CAUTION Loose welding terminal connections can cause overheating and result in the male plug being fused in the terminal. Remove any packaging material prior to use. Do not block the air vents at the front or rear of the Weld- ing Power Source.
OPERATION FABRICATOR 211i 4.10 Setup for MIG (FCAW) Welding with Gasless MIG Wire A. Select MIG mode with the process selection control (refer to Section 4.01.13 for further information). B. Connect the MIG polarity lead to the negative welding terminal (-). If in doubt, consult the electrode wire manu- facturer.
FABRICATOR 211i OPERATION 4.11 Setup for SPOOL GUN MIG (GMAW) Welding with Gas Shielded MIG Wire A. Select MIG mode with the process selection control (refer to Section 4.01.13 for further information). B. Connect the MIG polarity lead to the positive welding terminal (+). If in doubt, consult the electrode wire manu- facturer.
OPERATION FABRICATOR 211i 4.12 Setup for TIG (GTAW) Welding A. Select LIFT TIG mode with the process selection control (refer to Section 4.01.13 for further information). B. Connect the TIG Torch to the negative welding terminal (-). Welding current flows from the power source via heavy duty bayonet type terminals.

OPERATION FABRICATOR 211i 4.13 Setup for STICK (MMA) Welding A. Connect the Electrode Holder lead to the positive welding terminal (+). If in doubt, consult the electrode manu- facturer. Welding current flows from the Power Source via heavy duty bayonet type terminals. It is essential, however, that the male plug is inserted and turned securely to achieve a sound electrical connection.
FABRICATOR 211i OPERATION 4.14 Leak Testing the System Leak test the system before putting into operation. 1. Be sure that there is a valve in the downstream equipment to turn off the gas flow. 2. With the cylinder valve open, adjust the regulator to deliver the maximum required delivery flow rate.
