should be 6-10mm (as shown), see the
technological parameter
table behind for the values‘ choice.
▲Tungsten
electrode‘s
grinding
requirements
1: the diameter D of discharge tipped
platform is 0.2~0.8mm according to
different welding current (see process
table), equally, see process table for the
taper A.
2:Grinding marks on the cone is
required to array in radial order as shown.
3:G85E allows the tungsten electrode‘s
maximum cut-off length of 85mm, so the
purchased tungsten electrode of standard
length of 150mm can cut off 2 (75mm
each), maximumly reduce the loss of
tungsten electrode cut-off.
●
Adjustment of welding torch head‘s
obliquity
Loosen two M4 × 16 screws, we can make welding torch head‘s axis and the axis of welded
tube of 1~30 degrees angle. In principle, it can achieve making welding torch head‘s axis and
the axis of welded tube parallel and achieve vertical welding of weld plate. The angle of 1~30
degrees is defined as angle adjustment range here. Refer to the table of processing technical for
the angle value of specific welding process values.
●
Position adjustment of the wire nozzle
▲Releasing the flat head setting screw M5 × 8 can make the whole wire feeding joints rotate
around the ceramic nozzle axis through the insulation clip, to adjust the deflection angle of wire
into the weld crater. That is generally only used in the first coarse adjustment. The product is
adjusted well when out of the factory.
▲Releasing M4 × 10 inner hexagon fillister head screw can adjust the shaft to do
fore-and-aft displacement adjustment. The adjustment shaft has been done non-skid treatment.
So you need not tighten the screws with too much preload to avoid the clip‘s crack.
▲Loosen the inner hexagon fillister head screw M4 × 8 of adjustment shaft, you can adjust
the angle between output wire rod and the ceramic nozzle axis (that is the angle between
tungsten electrode‗s axis and the wire axis, Refer to the table of processing technical for the
angle value)
▲Release the M4 × 8 inner hexagon fillister head screw of the lower part of the figure; you
can adjust the distance between the wire nozzle and the weld crater.
