INTRODUCTION

DTE 255 is a compact welding power source for two different welding methods.
It can be used for:
S welding with tungsten electrodes (TIG), using direct or alternating current.
S manual metal arc welding with coated electrodes (MMA), using direct or
alternating current.
DTE 255 is available in two designs:
S with OKC connection for the TIG torch
with central connection for the TIG torch
S
Note: Remove the TIG torch when using the MMA method.
