The Smootharc MMA170 is a remarkablycapable
andexceptionallyportable machine
Introducing the Smootharc MMA170 With excellent arc stability
suitable for both MMA and lift arc TIG welding, the Smootharc
MMA170 is the ideal choice for a portable welding machine and
particularly suited to the repair and construction sectors. In
addition, the Smootharc MMA 170 comes complete with an operating
manual packed with safety tips and useful welding information.
The Smootharc MMA170 is designed to give you years of
trouble-free welding.
Compact and robust design is extremely portable with a tough
plastic outer case. The lightweight MMA170 is an ideal on-site
welding tool
Welding and earth cable are all included in the package Cooling
air flows forward from the rear of the machine which reduces
the
amount of dust and metal particles from entering the machines
interior High build quality is manufactured to IEC60974-1 and
ISO9001 quality
control system Fast changeover from MMA to TIG*

TIG Welding
Lift Arc TIG Welding
The BOC Smootharc MMA170 is easily adaptable for lift arc TIG
welding. Combining your TIG torch and BOC Smootharc MMA170 makes
high quality welding easy, wherever you need to go.
Lift arc TIG function enables easy arc starting.
Automatic hot start function for low risk of start defects.
* Optional items required for TIG weldingTIG Torch:
INVERWELD-TIG Regulator/Flowmeter: 105206
Note This machine is DC operation only and as such is not
suitable for the TIG welding of aluminium.
