(170A) for 3.0 minutes, i.e. arc welding time, out of every 10 minute period (30% of 10 minutes is 3.0 minutes). During the other 7.0 minutes of the 10 minute period the Welding Power Source must idle and be allowed to cool. A-11712 Figure 2-1: Transarc 170i Duty Cycle Manual 0-5280 Safety and Installation...
130A @ 60%, 15.2V 100A @ 100%, 14.0V Protection Class IP23S Table 2-1: Transarc 170i Specifications NOTE 1 Due to variations that can occur in manufactured products, claimed performance, voltages, ratings, all capacities, measurements, dimensions and weights quoted are approximate only. Achievable capacities and ratings in use and operation will depend upon correct installation, use, applications, maintenance and service.
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.
TRANSARC 170i 3. Radiation from Welding Leads: Radiated interference • Precautions must be taken against the power from welding leads, although pronounced in the vicinity source toppling over. The power source must be of the leads, diminishes rapidly with distance. Keeping located on a suitable horizontal surface in the leads as short as possible will minimise this type of upright position when in use.

TRANSARC 170i B. Assessment of Area Before installing welding equipment, the user shall make an assessment of potential electromagnetic problems in the surrounding area. The following shall be taken into account. 1. Other supply cables, control cables, signaling and telephone cables; above, below and adjacent to the welding equipment.

TRANSARC 170i A-11690 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.

TRANSARC 170i A-11714 Figure 4-3: Programming Mode STICK Programming Mode Programming Parameter Control Panel Display Hot Start This parameter operates in STICK mode to improve the start characteristics for stick electrodes HOT START current is on top of the BASE current.
Page 28
TRANSARC 170i Programming Parameter Control Panel Display Base Current This parameter sets the STICK weld current. Range is 5 to 170A. Factory default is 120A. Arc Force Arc Force is effective when in STICK mode only. Arc Force control provides an adjustable amount of Arc Force (or "dig") control.
Page 29
TRANSARC 170i Up Slope This parameter operates in TIG mode 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.
Page 30
TRANSARC 170i Crater Current This parameter operates in TIG mode 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 31
TRANSARC 170i 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.
Page 32
A-11725 STICK Dead Man Switch Mode (Transarc 170i Mines Spec Model) A special trigger mode called “Dead Man Switch” mode is available on the 170i when welding with STICK electrodes. In this mode, there will be no output voltage at all from the Power Source until the trigger is pressed.
Page 33
Note that if the Dead Man Switch function is disabled, 2T and 4T are not available in STICK mode. Information on how to disable the Dead Man Switch function is available from Cigweld Technical Customer Care on +61 3 9474 7400...
Page 34
TRANSARC 170i WARNING The Power Source must be turned off and unplugged from the mains supply before the Dead Man Switch function is changed. WARNING If 4T operation is selected when using the Dead man Switch mode, the use of and observer is recommended.
TRANSARC 170i 3.07 Shielding Gas Regulator Operating Instructions (where supplied) 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 36
TRANSARC 170i 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.
TRANSARC 170i 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.

Table 4-2 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.
TRANSARC 170i 3.10 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.
TRANSARC 170i 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.
