Welding; Selecting The Correct Welding Current - Honda EW171 Owner's Manual

Welding
m Welding is potentially a very hazardous activity. It should

A -
only be attempted by a trained welder with a thorough knowledge of
proper welding techniques and safety procedures. Be sure to read and
follow the safety rules on pages 3,4 and 5 of this manual.
1. Put the Engine Switch in the OFF position. Turn the AC circuit breaker off
and remove any plugs from the AC receptacles.
(1 Voltage is present at the welding terminals whenever the
engine is running regardless of the position of the AC/DC (WELD)
selector.
2. Connect the welding cables to the welder's DC terminals (See page 18 and
19).
I] Failure to use the proper gauge cable may lead to painful
burns and/or damage to equipment. See table on page 18.
3. Start the engine and when it has warmed up fully, turn the Auto-Throttle
Switch to the AUTO position.
4. Turn the AC/DC (WELD) selector to the DC (WELD) position.
5. Set the current adjustment knob to the proper current level for the job being
done (See page 18).
Selecting the Correct Welding Current
Measure the thickness of the metal you are welding and then refer to the table
below to select the proper electrode size and current setting
PLATE THICKNESS ELECTRODE DIAMETER CURRENT
IN INCHES IN INCHES SETTING
UP TO 3/16
l/16 50-100
UPTO l/4 3132 loo- 150
ABOVE l/8 l/8 125- 175
ABOVE l/4 5132 150-200
-1 Always make a sample weld on a piece of scrap material to be
sure you have chosen the correct electrode and current setting.
