TRANSTIG 170Pi 1.05 EMF Information Considerations About Welding And The Effects Of Low Frequency Electric And Magnetic Fields Welding current, as it flows through welding cables, will cause electromagnetic fields. There has been and still is some concern about such fields. However, after examining more than 500 studies spanning 17 years of research, a special blue ribbon committee of the National Research Council concluded that: “The body of evidence, in the committee’s judgment, has not demonstrated that exposure to power-frequency electric and magnetic fields is a human-health hazard.”...

Due to large variations in performance and specifications of different brands and types of generators, Cigweld cannot guarantee full welding output power or duty cycle on every brand or type of generator. Some small generators incorporate low cost circuit breakers on their outputs. These circuit breakers usually will have a small reset button, and will trip much faster than a switchboard type circuit breaker.

TRANSTIG 170Pi 2. Digital Meter (Amps and Volts) The digital meter is used to display the pre-set parameter values (when not welding) and actual output current or voltage (when welding) of the power source. A long press (>2s) on the Multi Function Control toggles between the display of amps and volts.

Page 30
TRANSTIG 170Pi Programming Parameter Control Panel Display Arc Force Arc Force is effective when in STICK mode only. Arc Force control provides an adjustable amount of Arc Force (or "dig") control. This feature can be particularly beneficial in providing the operator the ability to compensate for variability in joint fit-up in certain situations with particular electrodes.
Page 31
TRANSTIG 170Pi Up Slope This parameter operates in TIG modes only and is used to set the time for the weld current to ramp up from INITIAL current to BASE current. Range is 0.0 to 15.0 seconds. Factory default is 1.0 second. Base Current In DC TIG mode, this parameter sets the TIG welding current.
Page 32
TRANSTIG 170Pi Pulse Mode / Direct DC mode This parameter selects PULSE operating mode or DIRECT DC (-) operating mode. Range is DC or Pulse Mode. Factory default is DC. Trough Current This parameter sets the TIG TROUGH current. The lowest point in the pulse is called the Trough.
Page 33
TRANSTIG 170Pi Pulse Width This parameter sets the percentage “on” time of the PULSE FREQUENCY for BASE weld current when in PULSE operating mode. Range is 15 to 80%. Factory default is 50%. Pulse Frequency This parameter sets the PULSE FREQUENCY when in PULSE operating mode.
Page 34
TRANSTIG 170Pi Crater Current This parameter operates in TIG modes only. In 2T mode this is the current at the end of the down slope current ramp. When the welding current reaches the Crater Current value, the welding current will cease and the unit will enter Post Flow mode.
Page 35
TRANSTIG 170Pi CAUTION Loose welding terminal connections can cause overheating and result in the male plug being fused in the bayonet terminal. 7. Remote Control Socket The 8 pin Remote Control Socket is used to connect remote control devices to the welding power source. To make connections, align keyway, insert plug, and rotate threaded collar fully clockwise.
Page 36
TRANSTIG 170Pi A-11663 4T Latch Mode This mode of welding is mainly used for long welding runs to reduce operator fatigue. In this mode the operator can press and release the torch trigger and the output will remain active. To deactivate the power source, the trigger switch must again be depressed and released, thus eliminating the need for the operator to hold the torch trigger.
Page 37
TRANSTIG 170Pi Note that when the unit is powered on the mode selection control will automatically default to LIFT TIG/HF TIG mode. This is necessary so as to prevent inadvertent arcing should an electrode holder be connected to the unit and mistakenly be in contact with the work piece during power up. 11.
TRANSTIG 170Pi 4.02 Shielding Gas Regulator Operating Instructions WARNING This equipment is designed for use with welding grade (Inert) shielding gases only. Shielding Gas Regulator Safety This regulator is designed to reduce and control high pressure gas from a cylinder or pipeline to the working pressure required for the equipment using it.
Page 39
TRANSTIG 170Pi Installation 1. Remove cylinder valve plastic dust seal. Clean the cylinder valve outlet of impurities that may clog orifices and damage seats before connecting the regulator. Crack the valve (open then close) momentarily, pointing the outlet away from people and sources of ignition.
TRANSTIG 170Pi Shutdown Close cylinder valve whenever the regulator is not in use. To shut down for extended periods (more than 30 minutes). 1. Close cylinder or upstream valve tightly. 2. Open downstream equipment valves to drain the lines. Bleed gas into a well ventilated area and away from any ignition source.

TRANSTIG 170Pi Description The CIGWELD Foot Control is a foot operated switch and potentiometer which starts and stops the welding process and controls welding current through operation of the foot pedal. Refer to list below for compatible Cigweld power sources.
TRANSTIG 170Pi 4.05 Setup for Manual Arc (MMAW) Welding A. Connect the Electrode Holder lead to the positive welding terminal (+). If in doubt, consult the electrode manufacturer. Welding current flows from the Power Source via heavy duty bayonet type terminals. It is essential, however, that the male plug is inserted and turned securely to achieve a sound electrical connection.
TRANSTIG 170Pi SECTION 5: ThEORY OF OPERATION 5.01 Inverter Design What does the word inverter mean? The term inverter refers to the ability to change DC power into AC. Inverter power supplies immediately rectify the incoming AC to DC, and then the transistors create a higher frequency AC. The higher frequency AC then goes on to a much smaller main transformer than in a conventional power supply.
