INSTALLATION
Component setup of this welding machine is a simple, straight forward process. This welder is fitted with a Power Voltage
Compensator that takes into consideration a + / - 15% of the rated voltage for this machine. However it is most important to be
sure your power supply to this welding is of the proper voltage and is in good condition with clean connections, proper wiring
and the correct circuit breakers. It is strongly suggested that if longer leads are used for grounding that larger wire gauge is
used to reduce the possibility of line loss due to resistance.
Be sure when you are setting up your welding machine that the vents and fans are not obstructed and are allowed to flow air
freely.
The required Argon gas cylinder should only be connected to the welder through a proper regulator / flowmeter. The working
range of the gas flow (depending on the work being done) is approximately 20 cubic feet per hour (CFH) or 9.5 litres per
minute (LPM). All press on connection hoses should be further secured with a clamp to prevent inadvertent disconnects.
Snug connections to both the regulator, argon tank and welding machine. Over tightening any of these connections can
damage the equipment.
The tungsten electrode needs to be properly shaped to a point. When doing so it is recommended you use a dedicated grinding
wheel. Preferably a diamond coated wheel inexpensive and effective. Also note that while grinding the tungsten to a point, the
grinding marks should run longitudinally with the length of the tungsten rather than across the width of the tungsten to avoid
arc wander while the arc is finding ground as it welds.
Connecting the electrode and work (also called ground) cables correctly to your welder. Lets take a moment here to clarify what
can be a confusing subject to new users. Generically, when welding, the user has a choice of polarity connections. What is
correct for one type of welding may be totally wrong for another type of welding. So, lets explain what is happening and which
way to connect for which type of welding.
Electric current flows from negative to positive. When TIG welding the polarity settings should be
Straight Polarity Electrode
Negative!
That means that the Work clamp (aka ground) is connected to the Plus (+) Dinse connector, and not the negative as
some consider normal. Of course with the TIG function, the TIG electrode cable is screwed into its own dedicated threaded
receptacle, but rest assured this receptacle is the negative connector. When connecting the TIG Torch, a gentle snug
connection is all that is needed.
DO NOT OVER TIGHTED THE BRASS CONNECTOR.
When using the ACDCTIG200 in the MMA or Stick mode, the connection to the front of the welding machine is just the
opposite! Stick or MMA welding is done with
Reverse Polarity Electrode Positive!
That means when you are going to stick
weld with the ACDCTIG200 you must connect your electrode holder ( the one that holds your welding rod) to the
Positive Dinse
Connector
and you connect your work clamp (aka ground) to the
Negative Dinse Connector
.
Connecting the foot pedal or the TIG trigger button to the face of the welder for TIG Mode. When using the foot pedal which is
the most common way to TIG weld, connect the foot pedal to the push pin connector on the front of the welder.
NOTE: Be sure
the 2T function is the active setting on the face of the welder when using the foot pedal.
Connecting the torch trigger switch to the welder requires disconnecting the foot pedal plug, and instead plugging in the round
small push connector plug which is attached to the TIG Torch cable in its place. When using the TIG Trigger, you can choose
between 2T or 4T function. While the 2T function is the most common choice for TIG Trigger button use, the 4T may be an
option you wish to explore.
