Electrical Connection
• ARC 161 is designed to operate on a 10A 230V AC power
supply
• ARC 201 is designed to operate on a 15A 230V AC power
supply
The DURALLOY Multivoltage technology allows the machine to
operate on a very wide range input voltages down as low as
90V. This means that limited capacity power supplies and long
extension leads may be used without damaging the welder.
However, as the supply voltage decreases, the maximum output
current and duty cycle will also decrease. To utilise the full output
capacity of the machine using an extension cord, it should be a
heavy duty version with a minimum cable core size of 2.5mm

Operating Environment
Adequate ventilation is required to provide proper cooling for the
DURALLOY ARC 161/201. Ensure that the machine is placed on a
stable level surface where clean cool air can easily flow through
the unit. The DURALLOY ARC 161/201 has electrical components
and control circuit boards which may be damaged by excessive
dust and dirt, so a clean operating environment is important.
BASIC OPERATION
1. ARC/ MMA Welding Operation
1.1 Connect the earth cable quick connector to the negative
welding power output socket (5) Connect the earth clamp
to the work piece. Contact with the work piece must be firm.
Contact with clean, bare metal, with no corrosion, paint or
scale at the contact point.
1.2 Insert an electrode into the electrode holder and connect the
electrode holder and work lead to the positive welding power
output socket (4).
Note: This polarity connection configuration is valid for most GP (General Purpose)
MMA electrodes. There are variances to this. If in doubt, check the electrode
specifications or consult the electrode manufacturer.
1.3 Connect the machine to suitable mains power using the mains
input power lead. Switch the mains power switch to ‘on’ to
power up the machine. Select MMA welding mode (7) using
the button (8).
1.4 Select the required output current using the current control
knob (3). You are now ready to weld!

2. Lift TIG Operation
Note: Lift TIG operation requires an optional valve control TIG torch, and argon gas
cylinder.
2.1 Connect the earth cable quick connector to the positive
welding power output socket (4). Connect the earth clamp
to the work piece. Contact with the work piece must be firm
contact with clean, bare metal, with no corrosion, paint or
scale at the contact point.
2.2 Insert TIG torch power connection into the negative welding
power output socket (4). Connect valve TIG torch gas line to
the regulator, ensuring all connections are tight.
2.3 Open gas cylinder valve and adjust regulator, flow should
be between 5-10 l/min depending on application. Re-check
regulator flow pressure with torch valve open as static gas
flow setting may drop once gas is flowing.
2.4 Connect the machine to suitable mains power using the mains
input power lead. Switch the mains power switch to ‘on’ to
power up the machine. Select Lift TIG welding mode (6) using
the button (8).
2.5 Select the required output current using the current control
knob (3). You are now ready to weld!
