ELECTRODE GRINDING
To optimise the welding process, it is recommended to grind the electrode prior to welding as described below:
USAGE WARNING
Warning : EXATIG is not suitable for spot weld application with power over 200A as this might increase the wear of the product.
The contactor might get damaged in the process and will not be covered by the warranty.
Contactor 250A SU280 12V : Ref.51081.
USING THE FLOWMETER
TIG welding requires the protection of inert gas (Argon) A flowmeter is integrated into EXATIG giving the operator the possibility to adjust the gas
debit (argon) directly.
Debit adjustment possibility: 5-25 LPM (litre/min)
Precision: ± 5%
DEBIT GAS ADJUSTMENT :
The ball flowmeter must be located in a vertical position To use it, open the scroll wheel (FIG 1) and adjust the position of the ball based on the
debit required. The adjustment of the flow has to be when the torch trigger is pushed in.
WARNING, do not unscrew the wheel entirely when gas is open.
Increase flow :
Turn anticlockwise
Decrease the flow :
Turn clockwise
FLOW GAS READING :
Each scale matches with a flow, the top float (ball) must be at the level of the line in order to get the indicated flow.
Reading plan :
MAINTENANCE :
Clean outside the machine using soapy water. Clean and dry If using detergent products make sure they can be used on plastic Do not immerse
Inspect between 1 and 3 years according the use.
