Wire Reel Brake - Thermal Arc Fabricator 211i Operating Manual

FABRICATOR 211i

3.13 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. Correct adjustment will result in the wire reel circumference continuing no further
than 10-20mm after release of the trigger. The electrode wire should be slack without becoming dislodged from
wire spool.
Overtension of brake will cause rapid wear of mechanical WIREFEED parts, overheating of electrical
componentry and possibly an increased incidence of electrode wire Burnback into contact tip.
3.14 Setup for MIG (GMAW) Welding with Gas Shielded MIG Wire
A. Select MIG mode with the process selection control. (refer to Section 3.06.13 for further information)
B. Connect the MIG polarity lead to the positive welding terminal (+). If in doubt, consult the electrode wire 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.
C. Fit the MIG gun to the power source. (Refer to section 3.07 Attaching MIG gun).
D. Connect the work lead to the negative welding terminal (-). If in doubt, consult the electrode wire manufacturer.
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.
E. Fit the welding grade shielding gas regulator/flowmeter to the shielding gas cylinder, then connect the shielding
gas hose from the rear of the power source to the regulator/flowmeter outlet.
F. Refer to the Weld Guide located on the inside of the wirefeed compartment door for further information.
Before connecting the work clamp to the work make sure the mains power supply is switched off.
Secure the welding grade shielding gas cylinder in an upright position by chaining it to a suitable sta-
tionary support to prevent falling or tipping.
