Specifications

Transtig 200Pi, 250Pi, 300Pi
26
WARNING 5
When the welder is connected to the Mains supply voltage, the internal electrical components maybe at
240V potential with respect to earth.
10.7 Input Cable ‡
The input cable connects the Mains supply voltage to the equipment.
10.8 Gas Inlet ˆ
The Gas Inlet connects the welding gas to the in-built solenoid valve. A 5/8 18UNF male nut &
nipple is supplied with the Transtig 200Pi, 250Pi, 300Pi to connect a 5mm ID gas hose to the Gas
Inlet fitting.
11. Set-up For MMAW (Stick) and GTAW (TIG)
Conventional operating procedures apply when using
the Welding Power Source, i.e. connect work lead
directly to workpiece and electrode lead is used to
hold electrode. Wide safety margins provided by the
coil design ensure that the Welding Power Source will
withstand short term overload without adverse
effects. The welding current range values should be
used as a guide only. Current delivered to the arc is
dependent on the welding arc voltage, and as welding
arc voltage varies between different classes of
electrodes, welding current at any one setting would
vary according to the type of electrode in use. The
operator should use the welding current range values as
a guide, then finally adjust the current setting to suit the
application.

WARNING 6
Before connecting the work clamp to the work and inserting the electrode in the
electrode holder make sure the Mains power supply is switched off.
CAUTION 2
Remove any packaging material prior to use. Do not block the air vents at the front or rear or sides of the Welding
Power Source.
CAUTION 3
DO NOT change the Weld Mode or Weld Process Mode until after POST-FLOW time has finished.
12. Sequence Of Operation
NOTE 4
The control panels shown operation are the same for all models. The Transtig 200Pi control panels are shown
throughout this section. To view each individual weld parameter value press the left or right arrow buttons or press
the control knob.
