Rear Panel Controls
1) On-Off Switch
This switch controls the input power to your Invertig 130DC/HF
Welder. 0 is off and 1 is on.
When you turn the machine on, the power indicator lamp (#4)
will be illuminated green on the front panel of the welder. This
is an indication your Invertig 130DC/HF is on and ready for
use. If both the yellow thermo switch light (#3) and the green
power indicator light are on when you first turn the machine on,
it is a good indication that you have lost a leg of your 220.
2) Gas Connection
Connect the gas hose which is supplied with the machine to
the barbed gas connection fitting using the crimp type clamp
supplied with your welder. Connect the other end of the hose
to the regulator or flowmeter.
3) Remote Amperage Connection
This is where you will connect the foot pedal or the hand
amperage control. This will allow you to remotely control the
amperage of the welder
Shield Gas
TIG welding requires a shield gas of 100% Argon. A shield gas
is used to keep the surrounding atmosphere from coming in
contact with the molten weld puddle. The correct flow rate is
enough gas to shield the molten weld puddle and protect the
tungsten electrode. Any greater flow rate is a waste of shield
gas. Usually, the flow rate will be set anywhere between 15 and
30 cubic feet per hour (cfh).
Use a flow gauge such as HTP Part #12020 or a flow meter
such as the HTP Part #12020F which is compatible with
Argon cylinders and has a barbed fitting for the delivery hose.
Connect the gas hose to the gas fitting at the rear of the machine
and to the barbed fitting on the regulator.
HTP also has available small 60 cubic foot gas bottles
(Part #99900), which are ideal for use with your welder. These
bottles stand approximately 30" high and weigh less than 40
pounds, making your welder very easy to move around the shop.
Be sure to check with your local gas supplier about filling these
tanks before ordering.
If you already have a large cylinder, you can fill the small
cylinder from the large cylinder using the transfer manifold
(HTP Part #99905).
