GAS BOTTLE
ATTENTION! - CHECK FOR GAS LEAKS
At initial set up and at regular intervals we recommend to check for gas leakage
Recommended procedure is as follows:
1. Connect the regulator and gas hose assembly and tighten all connectors and clamps.
2. Slowly open the cylinder valve.
3. Set the flow rate on the regulator to approximately 10-15 l/min.
4. Close the cylinder valve and pay attention to the needle indicator of the contents pressure gauge on
the regulator, if the needle drops away towards zero there is a gas leak. Sometimes a gas leak can be
slow and to identify it will require leaving the gas pressure in the regulator and line for an extended time
period. In this situation it is recommended to open the cylinder valve, set the flow rate to 8-10 l/min,
close the cylinder valve and check after a minimum of 15 minutes. Ensuring adequate ventilation fore
small spaces.
5. If there is a gas loss then check all connectors and clamps for leakage by brushing or spraying with
soapy water, bubbles will appear at the leakage point.
6. Tighten clamps or fittings to eliminate gas leakage.
IMPORTANT! -
We strongly recommend that you check for gas leakage prior to operation of your
machine. We recommend that you close the cylinder valve when the machine is not in use.
BOSSWELD, authorised representatives or agents of BOSSWELD will not be liable or responsible for
the loss of any gas.
DUTY CYCLE:
Special note:
If this welders duty cycle is exceeded the welder will enter “thermal overload” which will
automatically stop the welding output in order to protect, both the user and the welder. You will know
the welder has gone into thermal overload when the overload error indicator light is illuminated.
The welder will then cool itself down, and once the overload error indicator light is no longer
illuminated, welding can then re-commence.
Please note. Exceeding the machine’s duty cycle, cannot be considered grounds for warranty or
return.
The term duty cycle indicates the percentage welding time available at the output current for each 10 min
period over 4 hours,
The specification plate on the machine list three given ratings at a given current and voltage.
NOTE: Amps refer to the Current setting - TIG DC setting duty cycle shown

170 - Amps

16.8 Volts

14.4 Volts
For example this means when the machine is set at a current of 170 Amps in TIG-AC it can only weld for
Two an a half minutes in a Ten minute period.
The power source is protected by a built in temperature protection device,
This will activate if the machine is operated in excess of its amperage and duty cycle rating.
