Technology Update
requires minimal operating training.
Overcoming the objectives of price
and complexity allows more industries
to benefit from the precision and
repeatability of orbital welding.
MAGNATECH had added a new, larger
model to its 800 series of orbital weld
heads. The new Model 860 fusion welds
tube from 50 to 150mm (2" to 6").
The company recently introduced
the 800 series, a line of enclosed
autogenous orbital weld heads that
utilise digital technology. Digital encoder
drive motors eliminate the need for
calibration. QC can quickly verify the
accuracy, but calibration will never
change over time.
The 860 is a compact and lightweight
150mm (6") head. Only 19mm (0.75") of
straight length is required – tungsten to
collet face. The 860 head is only 43mm
(1.7") wide, allowing its use in tight
clearance applications, welding fitting-
to-fitting or fitting-to-valve.
According to the company, new
construction techniques make the series
cost-effective, durable, and easy to
service in the field. A unique design,
over-close collet clamping system, and
an exclusive full exchange water cooling
system allow for true 100 per cent duty
cycle. Five models handle tube sizes
from 3 to 150mm (0.125" to 6") OD.
Magnatech also manufactures
the Tubemaster 517 model, which
integrates a controller and orbital head
with standard GTAW power supplies.
