Ross RXT200EX, Instructions Manual

Page: 14 / 20

To commence the welding process proceed as follows.
• Make sure that the earth clamp is firmly connected to the Work piece.
WARNING!
Ensure that you have your protective clothes, gloves and welding helmet cor-
rectly fitted before welding. Do not start welding before your eyes are properly protected
by the welding helmet.
You are now ready to execute the weld.
• Bring the wire into close proximity of the required weld start position. Keep the tip approximately 10-15 mm
away from the work piece and squeeze the trigger on the torch to commence welding.
• Adjust the wire feed rate for the job at hand see [18].
• Note: Adjustment of the welding voltage control [5] will override the automatic setting if required. The auto-
matic welding voltage setting will be restored if any adjustment to the wire feed speed control [18] is made.
Release the trigger to stop welding.
• When finished welding turn the welder off and the welding gas if applicable.
• Allow the weld to cool, clean the weld a wire brush. Always wear safety glasses when brushing or chipping slag
from a weld.
• Make sure the MIG gun has been set up correctly for Aluminium wire
- Teflon Liner, Correct tip for 1.0mm aluminium.
• Check pure argon welding gas is being used, is connected and is turned on.
• Fit 1.0mm U grove roller to the wire feed motor [F]
• Connect the welder to the mains supply and then turn the weld ON [I].
• Set the welding mode to MIG using the Welding mode switch [16]
• Set to 2 STEP mode see [14]
• Set the welding material type (AL) see [9]
• Set the type of welding gas to Co2+Argon mix see [5] (use Co2+Argon setting for Pure Argon)
• The size of the welding wire will automatically be set to 1.0mm see [7]
The welder will then automatically set the appropriate welding voltage.
• Clean the surfaces to be welded with a wire brush, make sure there is no oxidation or oil /grease.
ALUMINIUM
Note: Only 1.0 mm Aluminium welding wire can be used with this welder.
Aluminium MIG welding requires a much higher skill level that mild steel etc. It is best to seek ad-
ditional information and or training before attempting this type of welding.
Note: Before you start make sure that the quality and type of the aluminium material be welded
is suitable for this type of welding. Some aluminium alloys contain other metals and impurities
which will make them almost impossible to weld even for a skilled operator.
