This demonstrates that where the upper limit of current is limited by machine capacity and duty cycle, higher deposition rates and
therefore greater productivity will be achieved by using smaller electrode wire. The TRANSMIG is a particularly efficient MIG
welder with the 0.9mm steel wire in spray transfer mode. The savings from decreased welding time will more than cover the
small cost penalty of the smaller electrode wire sizes. (0.9mm wire cost approximately 10% more than 1.2mm, but is deposited
approximately 15% faster).
Higher current density (or smaller diameter wire) also gives deeper penetration
SECTION 13: Routine Maintenance & Inspection
The only routine maintenance required for the TRANSMIG 225, 255 MIG Power Source and TRANSMIG 255 2R Wirefeeder is a
thorough cleaning and inspection, with the frequency depending on the usage and the operating environment.
WARNING 10
There are dangerous voltage and power levels present inside this product. Do not attempt to open or repair unless you
are a qualified electrical tradesperson. Disconnect the Welding Power Source from the Mains Supply Voltage before
disassembling.
Special maintenance is not necessary for the control unit parts in the Power Source. If these parts are damaged for any reason,
replacement is recommended.
CAUTION 4
Do not blow air into the Power Source during cleaning. Blowing air into the Power Source can cause metal particles to
interfere with sensitive electronic components and cause damage to the Power Source.
To clean the Power Source, disconnect it from the Mains Supply then open the enclosure and use a vacuum cleaner to remove any
accumulated dirt and dust. The Power Source should also be wiped clean. If necessary, solvents that are recommended for cleaning
electrical apparatus may be used.
Troubleshooting and repairing the TRANSMIG 225, 255 MIG Power Source and TRANSMIG 255 2R Wirefeeder should be carried out
only by those who are familiar with electrical equipment.
13.01 Cleaning the Feed Rolls
Clean the grooves in the drive rolls frequently. This can be done by using a small wire brush. Also wipe off, or clean the grooves on the
upper feed roll. After cleaning, tighten the feed roll retaining knobs.
