S
Protect your eyes and body. Use the correct welding screen and filter lens and wear protective
clothing.
S
Protect bystanders with suitable screens or curtains.
FIRE HAZARD
S
Sparks (spatter) can cause fire. Make sure therefore that there are no inflammable materials nearby.

INTRODUCTION
Tradesmig 141 are step controlled power sources in a compact design, intended for welding with
solid steel, stainless steel or aluminium wire as well as tubular wire with or without shielding gas.The
possibility of welding with homogeneous wire/shielding gas and welding with gasless tubular wire is
obtained by switching the + and -- connections on the switching terminal by the wire feed unit.
ESAB’s accessories for the product can be found on page 15.

Inspection and cleaning
Check regularly that the power source is free from dirt.
The power source should be regularly blown clean using dry compressed air at reduced
pressure. More frequently in dirty environments. Otherwise the air inlet/outlet may become blocked and cause overheating.
-- 10 -T141e
Welding gun
Cleaning and replacement of the welding gun’s wear parts should take place at
regular intervals in order to achieve trouble--free wire feed. Blow the wire guide
clean regularly and clean the contact tip.
