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.
CONNECT SHIELDING GAS
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. After connecting your flow regulator to both the argon tank and the back of your TIG welder, your
connections are complete. When initially opening the valve on your argon tank, take care to gently crack it open at first so as not
to shock the flow regulator. Once argon reaches the flow regulator you can proceed to open the argon tank valve fully.
SHARPEN TUNGSTEN ELECTRODE
Note
:
WARNING! Some Electrodes may have materials added to them that are hazardous to breat
he. Wear a respirator and ANSI-approved Safety goggles when grinding an Electrode.
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. The general rule of thumb for sharpening your tungsten is to sharpen it
twice to 2 ½ times the diameter of the tungsten you have chosen to use. One technique you may find useful is to place the
unshaped tungsten in your cordless drill while sharpening it. That can help produce a more uniform taper.
ASSEMBLE TIG TORCH
The TIG torch consists of the pink in color ceramic end called a “cup”, the white insulator on the torch body, the “collet body”
the “collet” the “back cap” (which comes in different lengths) and of course the tungsten. Screw your “collet body” into the
front of the TIG torch past the white insulator. Slide your “collet” into the back side of your torch head with the larger end
sticking out. From the back side, slide your shaped tungsten into the “collet” and allow it to protrude slightly out the front of the
torch. Then install your “back cap” and gently snug it. Screw your “cup” onto the front of your torch until it gently snugs
against the white insulator. Tungsten cups all have numbers on them. The numbers designate the diameter of the opening of
that “cup” in 1/16 ths of an inch. So a number 8 cup for example has a ½ inch opening. As a general rule of thumb, the
tungsten should protrude past the opening of the “cup” no more than the diameter of that cup.
